Description

Technical Field

[0001] This application relates to the field of beauty care technology, and in particular to a method and apparatus for promoting the penetration of hair care compositions. Background Technology

[0002] In related technologies, the penetration effect of hair styling compositions such as hair dyes and conditioners directly affects hair quality and user experience. For plant-based dyes (such as henna powder and indigo), their pigment molecules are large, lacking chemical openers, resulting in extremely slow natural penetration, typically requiring 3-4 hours for color development, and the color is light and easily fades. While synthetic chemical dyes have some penetration ability, they are still limited by the high viscosity of the dye and mainly rely on natural diffusion, leading to long color development times and poor uniformity.

[0003] Traditional heating caps use convection or conduction heating, which provides some heat but easily leads to moisture loss, drying, and crusting of the hair dye, thus blocking the diffusion channels. Furthermore, uncontrollable temperature can easily cause scalp burns and hair damage (keratin denaturation). In addition, many existing vibration devices use mechanical rotary motors to generate vibration, whose energy attenuates significantly in the air, making it difficult to effectively act on the thick hair dyeing medium; simultaneously, mechanical vibration can easily cause user discomfort (such as tinnitus and headache) through skull conduction. Existing equipment generally lacks systematic and coordinated control of humidity, temperature, and multi-physical field energy during the hair dyeing process, resulting in poor repeatability of penetration enhancement effects and difficulties in cleaning and maintenance.

[0004] Therefore, how to safely, efficiently, and comfortably promote the penetration of hair care compositions onto the hair surface without relying on chemical penetrants has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0005] The main objective of this application is to provide a method and apparatus for promoting the penetration of hair care compositions, aiming to solve the technical problem of low penetration efficiency of hair care compositions in the prior art.

[0006] To achieve the above objectives, this application proposes a method for enhancing the penetration of a hair-dyeing composition, the method comprising:

[0011] In one embodiment, the step of applying the hair-care composition to the target hair surface further includes: Obtain the user's hair texture characteristics; The output parameters of the far-infrared radiation energy and the acoustic energy are dynamically adjusted based on the hair quality characteristics to achieve personalized penetration enhancement for users with different hair quality characteristics.

[0012] Furthermore, to achieve the above objectives, this application also proposes a penetration-enhancing device for a hair styling composition, the penetration-enhancing device comprising: A housing assembly for forming a receiving space that can cover the user's head area; A flexible interface layer is provided to construct a permeation-promoting reaction chamber between the outer shell assembly and the user's head area and to maintain the humidity balance within the permeation-promoting reaction chamber. The flexible interface layer is provided with several positioning through holes, and the edge of the flexible interface layer is provided with an elastic fastening ring. The elastic fastening ring is sleeved on the fixing interface structure of the outer shell assembly to tension and fix the flexible interface layer to the outer shell assembly. An adaptive suspension support mechanism includes a plurality of support units disposed inside the outer shell assembly, the plurality of support units passing through the plurality of positioning through holes and abutting against the user's head area; A far-infrared heating component is disposed inside the outer shell component. The far-infrared heating component is used to radiate far-infrared energy into the permeation-enhancing reaction chamber to adjust the rheological properties of the hair-care composition. An acoustic excitation component is disposed on the housing assembly and is used to directly apply acoustic energy to the permeation-enhancing reaction chamber through electro-deformation; A control component is electrically connected to the far-infrared heating component and the acoustic excitation component, and the control component is used to coordinately control the far-infrared energy and the acoustic energy.

[0013] Optionally, the far-infrared heating component of the penetration-enhancing device of the hair styling composition emits a far-infrared wavelength in the range of 8μm to 14μm, and the far-infrared heating component is used to maintain the working temperature of the containing space within a preset working temperature range of 38°C to 45°C; the acoustic energy frequency output by the acoustic excitation component is in a first frequency range of 2kHz to 5kHz and / or in a second frequency range of 25kHz to 50kHz.

[0014] Optionally, the acoustic energy applied by the acoustic excitation component at 2 kHz to 5 kHz is used to generate macroscopic disturbances in the hair styling composition, and the acoustic energy applied by the acoustic excitation component at 25 kHz to 50 kHz is used to generate microscale acoustic flow in the hair styling composition.

[0015] Optionally, the support unit of the penetration-enhancing device of the hair styling composition includes a vibration decoupling structure having nonlinear damping characteristics to absorb residual mechanical vibrations generated by the acoustic excitation component, thereby limiting vibration energy transmission to the user through the solid.

[0016] Optionally, the inner wall of the outer shell assembly of the hair-dyeing composition's penetration-enhancing device is provided with an energy-reflecting layer, which is a nano-silver coating or a vacuum-plated aluminum coating, for secondary focusing of the far-infrared energy and the acoustic energy.

[0017] Optionally, the penetration-enhancing device of the hair-care composition further includes: A red light array, located inside the housing assembly, is used to radiate visible red light energy into the permeation-enhancing reaction chamber to improve the user's wearing comfort during device operation.

[0018] Optionally, the flexible interface layer is connected to the housing assembly or the user's head via a fixed interface structure, wherein the fixed interface structure is selected from one or more of elastic fasteners, mechanical locking components, adhesive components, or magnetic components.

[0019] Optionally, the support unit of the adaptive suspension support mechanism is provided with a sealing skirt. The sealing skirt presses against the edge of the positioning through hole of the flexible interface layer in the supported state, so that the flexible interface layer is stretched by the support unit and divided into a number of stretched and tensioned sub-interfaces. The stretched and tensioned sub-interfaces are used to reduce the energy loss of the acoustic energy sent by the acoustic excitation component into the permeation reaction chamber.

[0020] One or more technical solutions proposed in this application have at least the following technical effects: Compared to related technologies that rely solely on natural diffusion or a single heating method, this application promotes the penetration of the hair-care composition within a safe temperature range by constructing a penetration-enhancing reaction chamber and applying the synergistic effect of far-infrared radiation energy and acoustic energy. Specifically, this application involves coating the target hair surface with the hair-care composition; forming a penetration-enhancing reaction chamber on the target hair surface through a flexible interface layer; applying far-infrared radiation energy within the penetration-enhancing reaction chamber to adjust the rheological properties of the hair-care composition; applying acoustic energy within the penetration-enhancing reaction chamber to generate acoustic flow within the hair-care composition; and maintaining the penetration-enhancing reaction chamber and the synergistic effect of the far-infrared radiation energy and the acoustic energy for a preset time to promote the diffusion and penetration of the hair-care composition on the target hair surface. After the hair dye composition is applied to the hair surface, the penetration-enhancing reaction chamber formed by the flexible interface layer effectively locks in moisture, preventing the dye from drying and forming a crust, and ensuring that the diffusion channels remain unobstructed during subsequent energy application. Far-infrared radiation energy is applied to the penetration-enhancing reaction chamber, adjusting the rheological properties of the hair dye composition to reduce its viscosity, making the active ingredients easier to move on the hair surface. Simultaneously, acoustic energy is applied, generating acoustic flow within the hair dye composition. This acoustic flow effect physically presses the pigments and other active ingredients into the gaps in the hair cuticle, significantly improving penetration efficiency. By maintaining the penetration-enhancing reaction chamber and the synergistic effect of the far-infrared radiation energy and the acoustic energy, the diffusion and penetration of the hair dye composition on the hair surface can be significantly promoted within a safe temperature range. This shortens the color development time, improves color uniformity, and avoids scalp burns and hair damage caused by high temperatures. Therefore, based on the method and apparatus of this application, efficient, safe, and comfortable hair dye composition penetration can be achieved without relying on chemical penetrants, overcoming the technical defects of low penetration efficiency in existing hair dye compositions and ultimately optimizing the hair care process.

[0021] The accompanying drawings, which are incorporated in and form part of this specification, illustrate embodiments consistent with this application and, together with the description, serve to explain the principles of this application.

[0022] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, for those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0024] The purpose, features, and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0025] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0026] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0027] The main solution in this application embodiment is: Apply a hair care composition to the surface of the target hair; The flexible interface layer of the penetration-enhancing device for hair styling compositions creates a closed or semi-closed penetration-enhancing reaction chamber on the surface of the target hair. Far-infrared radiation energy is applied in the permeation-enhancing reaction chamber to adjust the rheological properties of the hair-care composition; Acoustic energy is applied in the permeation-enhancing reaction chamber to generate acoustic flow in the hair composition; The synergistic effect of the permeation-promoting reaction chamber, the far-infrared radiation energy, and the acoustic energy is maintained for a preset time to promote the diffusion and penetration of the hair-care composition on the target hair surface.

[0028] In this embodiment, the application uses a penetration-enhancing device for hair-beautifying compositions as the main execution body. For ease of description, it will be referred to as "device" in detail below.

[0029] The lack of systematic and coordinated control over humidity, temperature, and multi-physical field energy during the hair styling process in existing technologies results in low penetration efficiency of hair styling compositions (especially macromolecular plant pigments), long color development time, and poor uniformity. Traditional heating methods also easily cause moisture loss, drying of the dye, and heat damage to the scalp. At the same time, single-frequency vibration devices can easily cause user discomfort, and the difficulty in equipment maintenance also limits the widespread adoption in home settings.

[0030] This application provides a solution that effectively locks in the moisture of the hair-dyeing composition by constructing a closed or semi-closed permeation-enhancing reaction chamber formed by a flexible interface layer, preventing it from drying or crystallizing during heating and ensuring that the diffusion channels remain unobstructed. Within this permeation-enhancing reaction chamber, far-infrared radiation energy, acoustic energy, and visible red light energy are simultaneously applied, maintaining a non-linear synergistic effect among the three. Far-infrared radiation energy is used to regulate the rheological properties of the hair-dyeing composition, reducing its viscosity to improve fluidity; acoustic energy generates micro-vortices within the hair-dyeing composition through a sono-induced flow effect, physically pressing pigments and other active ingredients into the hair cuticle gaps; and visible red light energy nourishes the scalp, alleviating sensitivity and discomfort during the hair dyeing process. The three energies reinforce each other in a closed, high-humidity environment, producing a non-linear synergistic effect that significantly enhances the diffusion rate and penetration depth of the hair-dyeing composition on the hair surface within a safe temperature range. Therefore, this application achieves multiple benefits such as shortening the color development time, improving color development uniformity, avoiding heat damage, and improving user experience without relying on chemical penetrants. It fundamentally solves the technical problems of low penetration efficiency, long color development time, poor uniformity, and scalp damage caused by high temperature in existing hair-beautifying compositions.

[0031] Based on this, embodiments of this application provide a method for enhancing the penetration of a hair-dressing composition, referring to... Figure 1 , Figure 1 This is a schematic flowchart of the first embodiment of the penetration enhancement method for the hair-dyeing composition of this application.

[0032] In this embodiment, the method for promoting the penetration of the hair-care composition includes steps S10 to S50: Step S10: Apply the hair styling composition to the surface of the target hair. It should be noted that "target hair" refers to the hair in the area of ​​the user's head to be treated, including but not limited to all or part of the hair strands. "Hair styling composition" refers to various preparations used in hair care, including but not limited to plant-based dyes such as henna powder and indigo, synthetic chemical dyes, semi-permanent colorants, and scalp care serums. Application methods may include manual application, brushing, or application with the aid of a device to ensure the composition evenly covers the hair surface.

[0033] Understandably, this step lays the material foundation for the entire penetration enhancement process. By uniformly coating the hair care composition onto the target hair, the subsequent energy action can directly act on the interface between the active ingredients and the hair, providing the prerequisite for efficient penetration.

[0034] Step S20: A closed or semi-closed penetration-enhancing reaction chamber is constructed on the surface of the target hair through the flexible interface layer of the penetration-enhancing device for the hair composition. It should be noted that the penetration-enhancing reaction chamber refers to a closed or semi-closed space formed between the target hair surface and the energy application interface through the flexible interface layer of the penetration-enhancing device. This space has adjustable humidity conditions and a preset energy gap to accommodate the hair-plasticizing composition and provide a stable physical environment for its penetration process. Construction methods include, but are not limited to, forming the space by adhering the flexible interface layer to the hair surface, or by maintaining the preset energy gap through a support mechanism.

[0035] Understandably, this step, by constructing a permeation-enhancing reaction chamber, effectively limits the excessive evaporation of moisture in the hair-care composition, preventing it from drying or crystallizing during subsequent energy application, ensuring that the diffusion channels remain unobstructed, and providing a stable working space for the uniform application of far-infrared radiation energy and acoustic energy.

[0036] Step S30: Apply far-infrared radiation energy to the permeation-enhancing reaction chamber to adjust the rheological properties of the hair-care composition; It should be noted that far-infrared radiation energy refers to infrared radiation with wavelengths between 8 and 14 micrometers, generated by a far-infrared heating component. This component includes, but is not limited to, a carbon-based heating coating such as a carbon fiber coating or a graphene coating encapsulated within a polyimide film. Rheological properties refer to the physical properties of the hair-care composition, such as viscosity, flowability, and spreadability. By maintaining the temperature of the penetration-enhancing reaction chamber within a preset temperature range using far-infrared radiation energy, the viscosity of the hair-care composition can be effectively reduced, and its rheological properties can be maintained at a preset state.

[0037] Understandably, this step raises the temperature of the hair-care composition to the working temperature range by applying far-infrared radiation energy in the permeation-enhancing reaction chamber, thereby reducing its viscosity and improving its fluidity. This makes it easier for the active ingredients to spread and move on the hair surface, creating favorable medium conditions for the subsequent physical drive of acoustic energy.

[0038] Step S40: Apply acoustic energy in the permeation-enhancing reaction chamber to generate acoustic flow in the hair composition; It should be noted that acoustic energy refers to the sound wave energy generated by acoustic excitation components, including but not limited to all-solid-state energy arrays composed of piezoelectric transducers, which directly generate acoustic energy through electro-induced deformation without mechanical moving parts. Acoustic flow refers to the steady-state fluid motion caused by sound wave energy attenuation and nonlinear interactions as sound waves propagate in a viscous liquid medium, including but not limited to the formation of directional microflow fields and localized microvortices within the hair styling composition. The application method includes, but is not limited to, applying acoustic energy to the penetration-enhancing reaction chamber through frequency sweeping.

[0039] Understandably, this step applies acoustic energy into the penetration-enhancing reaction chamber, utilizing the acoustic flow effect to generate micro-vortices and directional micro-flow fields within the hair styling composition. This effectively breaks the liquid surface tension of the hair styling composition, physically pressing effective ingredients such as pigments into the gaps in the hair cuticles of the target hair, significantly improving penetration efficiency and uniformity.

[0040] Step S50: Maintain the synergistic effect of the permeation-promoting reaction chamber, the far-infrared radiation energy, and the acoustic energy for a preset time to promote the diffusion and penetration of the hair-beautifying composition on the target hair surface.

[0041] It should be noted that the preset time refers to the processing time set according to the user's hair type, the type of hair styling composition, and the desired effect, including but not limited to 30 to 60 minutes. Synergistic effect refers to the mutually reinforcing and complementary functions of far-infrared radiation energy and acoustic energy when they work together in the same penetration-enhancing reaction chamber. Far-infrared energy reduces the viscosity of the hair styling composition, creating better medium conditions for acoustic energy drive, while the flow generated by acoustic energy makes the hair styling composition more evenly distributed and more fully heated. The two form a virtuous cycle, producing a penetration-enhancing effect that surpasses the simple superposition of single energy sources. Diffusion and penetration refer to the process by which the effective ingredients in the hair styling composition spread on the hair surface and enter the gaps in the hair cuticle and the interior of the hair shaft.

[0042] Understandably, this step significantly shortens the color development time of the hair styling composition within a safe temperature range by maintaining a stable environment in the penetration-enhancing reaction chamber throughout the entire processing cycle and through the synergistic effect of far-infrared radiation energy and acoustic energy. This improves color uniformity and saturation while avoiding moisture loss, scalp burns, and user discomfort caused by traditional heating methods. Ultimately, it achieves a highly efficient, safe, and comfortable penetration-enhancing effect for the hair styling composition.

[0043] This embodiment provides a method for enhancing the penetration of a hair styling composition. The method involves coating the hair styling composition onto the surface of target hair; constructing a closed or semi-closed penetration-enhancing reaction chamber on the target hair surface using a flexible interface layer of a penetration-enhancing device for the hair styling composition; applying far-infrared radiation energy into the penetration-enhancing reaction chamber to adjust the rheological properties of the hair styling composition; applying acoustic energy into the penetration-enhancing reaction chamber to generate acoustic flow within the hair styling composition; and maintaining the synergistic effect of the penetration-enhancing reaction chamber, the far-infrared radiation energy, and the acoustic energy for a preset time to promote the penetration of the hair styling composition. The diffusion and penetration of the hair dye onto the target hair surface: After the hair dye composition is applied to the hair surface, the penetration-enhancing reaction chamber formed by the flexible interface layer effectively locks in moisture, preventing the dye from drying and forming a crust, ensuring that the diffusion channels remain unobstructed during subsequent energy application. Far-infrared radiation energy is applied to the penetration-enhancing reaction chamber, adjusting the rheological properties of the hair dye composition to reduce its viscosity, making it easier for the active ingredients to move on the hair surface. Simultaneously, acoustic energy is applied, generating acoustic flow within the hair dye composition. This acoustic flow effect physically presses the pigments and other active ingredients into the gaps in the hair cuticle, significantly improving penetration efficiency. By maintaining the penetration-enhancing reaction chamber and the synergistic effect of the far-infrared radiation energy and the acoustic energy, the diffusion and penetration of the hair dye composition on the hair surface can be significantly promoted within a safe temperature range. This shortens the color development time, improves color uniformity, and avoids scalp burns and hair damage caused by high temperatures. Therefore, based on the method and apparatus of this application, efficient, safe and comfortable hair care composition penetration can be achieved without relying on chemical penetrants, thereby overcoming the technical defects of low penetration efficiency of hair care compositions in the prior art, and ultimately optimizing the hair care process.

[0044] In one feasible implementation, the step of applying far-infrared radiation energy in the permeation-enhancing reaction chamber includes: The temperature of the permeation-enhancing reaction chamber is maintained within a preset temperature range by using far-infrared radiation energy, thereby reducing the viscosity of the hair care composition and maintaining the rheological properties of the hair care composition in a preset state.

[0045] It should be noted that the preset temperature range refers to a temperature range pre-set according to the type of hair styling composition, the user's hair type, and safety requirements, including but not limited to the physiologically safe range of 38 degrees Celsius to 45 degrees Celsius. Reducing the viscosity of the hair styling composition means increasing the temperature to intensify the thermal motion of molecules in the composition and weaken intermolecular forces, thereby enhancing its fluidity and making it easier to spread and penetrate the hair surface. Maintaining the preset rheological properties means that the flow behavior of the hair styling composition is optimized to a state suitable for subsequent energy application, including but not limited to reduced shear viscosity, improved spreadability, and improved wetting properties.

[0046] Understandably, by maintaining the temperature of the penetration-enhancing reaction chamber within a preset temperature range, the viscosity of the hair-care composition can be effectively reduced without causing thermal damage, improving its flow and diffusion behavior on the hair surface. This creates favorable medium conditions for the subsequent physical driving effect of acoustic energy, allowing the acoustic flow effect to play a more significant role, delivering the active ingredients in the hair-care composition more efficiently to the hair cuticle, thereby significantly enhancing the overall penetration-enhancing effect.

[0047] In one feasible implementation, the step of applying acoustic energy in the permeation-enhancing reaction chamber includes: Acoustic energy is applied to the permeation-enhancing reaction chamber by sweeping frequency, so as to break the liquid surface tension of the hair styling composition through the acoustic flow effect and press the hair styling composition into the cuticle gaps of the target hair.

[0048] It should be noted that frequency sweeping refers to an output mode in which the frequency of acoustic energy changes continuously or piecewise within a preset range over time, including but not limited to linear frequency sweeping, logarithmic frequency sweeping, periodic frequency sweeping, or piecewise frequency sweeping. Acoustic flow effect refers to the steady-state fluid motion caused by sound wave energy attenuation and nonlinear interaction when sound waves propagate in a viscous liquid medium, which can form directional microflow fields and local microvortices within the hair styling composition. Breaking liquid surface tension refers to overcoming the cohesive forces between molecules of the hair styling composition and the interfacial tension between the hair styling composition and the hair surface through sound wave energy, making it easier to spread and penetrate. Cuticle gaps refer to the microscopic gaps formed by the overlapping cuticle scales on the hair surface, which are the main channels for the effective ingredients in the hair styling composition to enter the hair shaft.

[0049] Understandably, applying acoustic energy through frequency sweeping can induce a continuous and stable acoustic flow effect in the hair styling composition. The generated microvortices and directional microfluidic fields effectively break the surface tension of the liquid in the hair styling composition, allowing it to more fully penetrate the hair surface and enter the cuticle crevices. Simultaneously, the frequency sweeping method can cover a wider frequency range, adapting to the dynamic response characteristics of hair styling compositions with different viscosities. This avoids the uneven energy distribution problems that may occur with a single frequency, thereby physically pressing the active ingredients in the hair styling composition into the cuticle crevices, significantly improving penetration depth and uniformity, and achieving highly efficient penetration.

[0050] In one feasible implementation, the step of applying acoustic energy in the permeation-enhancing reaction chamber to generate acoustic flow in the hair composition includes: Controllable visible red light energy is applied to the permeation-enhancing reaction chamber to dynamically control the heat distribution of the chamber, thereby improving the user's wearing comfort during device operation.

[0051] It should be noted that visible red light energy refers to light radiation with wavelengths in the red band of the visible spectrum, including but not limited to the range of 620 nm to 740 nm, with 630 nm wavelength visible red light being preferred. "Controllable" means that the output intensity, duration, or pulse frequency of the visible red light energy can be adjusted according to preset programs or user needs to achieve precise control of the thermal field within the osmosis-enhancing reaction chamber. "Dynamically controlled heat distribution" refers to the active adjustment of the temperature field within the osmosis-enhancing reaction chamber using visible red light energy, including but not limited to promoting local microcirculation to assist in uniform heat distribution, regulating scalp surface temperature perception, and reducing the potential accumulation of localized heat due to prolonged energy application. "Wearing comfort" refers to the comprehensive evaluation of the user's subjective experience during device use, including but not limited to the appropriateness of the warmth, the gentleness of the vibration, the soothing sensation in the scalp area, and the tolerance for prolonged wear.

[0052] Understandably, this embodiment applies controllable visible red light energy on top of far-infrared radiation and acoustic energy, utilizing its dynamic adjustment of heat distribution within the penetration-enhancing reaction chamber to provide users with a more uniform and comfortable warming experience throughout the entire preset treatment cycle. This enhanced comfort encourages users to maintain the preset treatment time, indirectly ensuring the synergistic effect of far-infrared radiation and acoustic energy is fully realized. This guarantees that the penetration efficiency and uniformity of the hair-dyeing composition meet design goals, further optimizing the user experience while achieving highly efficient penetration.

[0053] In one feasible implementation, the step of applying the hair-care composition to the target hair surface further includes: Obtain the user's hair texture characteristics; Based on the hair quality characteristics, the output parameters of far-infrared radiation energy and acoustic energy are dynamically adjusted to provide personalized penetration enhancement for users with different hair quality characteristics.

[0054] It should be noted that hair quality characteristics refer to parameters used to characterize the state and properties of a user's hair, including but not limited to one or more of the following: coarse, normal, or fine hair. These may also include indicators such as hair damage level, porosity, water absorption, and oil content. Acquisition methods include, but are not limited to, receiving the user's manually selected hair type via an input interface, or automatically identifying hair quality characteristics through sensors detecting the hair's physical parameters. Dynamic adjustment refers to the process of automatically calculating and changing energy output parameters based on the acquired hair quality characteristics information through control components. Adjustment methods include, but are not limited to, proportional adjustment, threshold switching, or adaptive algorithm optimization. Output parameters refer to the variables controlling the output of far-infrared radiation energy and acoustic energy, including but not limited to the temperature curve, heating duration, and power density of far-infrared radiation energy, and the frequency distribution, sweep range, duty cycle, fluctuation period, and output intensity of acoustic energy. Personalized penetration enhancement refers to customizing differentiated energy output schemes according to the different hair quality characteristics of different users, enabling the hair styling composition to achieve optimal penetration effects under various hair quality conditions.

[0055] Understandably, this implementation method achieves an upgrade from standardized treatment to personalized precision care by acquiring the user's hair quality characteristics and dynamically adjusting the output parameters of far-infrared radiation energy and acoustic energy based on this information. Different hair types exhibit significant differences in their energy response characteristics. Coarse and stiff hair, with its dense cuticle structure, requires stronger or longer energy to open the penetration channels, while fine and soft hair, with its relatively loose structure, requires gentler energy parameters to avoid overtreatment. The dynamic adjustment mechanism ensures that each hair type completes the penetration-enhancing process under optimal energy conditions, avoiding poor penetration due to insufficient energy or unnecessary heat accumulation due to excessive energy. This significantly improves the penetration uniformity and adaptability of the hair care composition, further optimizing the user experience and the quality of hair care.

[0056] It should be noted that the above examples are only for understanding this application and do not constitute a limitation on the penetration enhancement method of the hair styling composition of this application. Any simple modifications based on this technical concept are within the protection scope of this application.

The support unit passes through the positioning through-hole and abuts against the user's head area. This means that the support unit penetrates from the inside of the flexible interface layer, positioning the flexible interface layer in a predetermined position. Simultaneously, the end of the support unit contacts the scalp surface or hair layer to form a physical support point, thereby maintaining a preset energy gap between the outer shell assembly and the hair.

Far-infrared heating components include, but are not limited to, carbon-based heating coatings such as carbon fiber coatings or graphene coatings encapsulated within a polyimide film. The acoustic excitation component refers to an element disposed within the housing assembly to generate acoustic energy. This component is an all-solid-state energy array that directly generates acoustic energy through electro-deformation. It includes, but is not limited to, arrays composed of piezoelectric transducers, requiring no mechanical moving parts. Electro-deformation refers to the phenomenon where piezoelectric materials undergo mechanical deformation under the action of an electric field, directly converting electrical energy into acoustic energy through this effect. The control component refers to a circuit unit electrically connected to the far-infrared heating component and the acoustic excitation component. It includes, but is not limited to, microcontrollers, digital signal processors, and programmable logic controllers, used to coordinate the control of far-infrared energy and acoustic energy according to preset programs or user input. Synergistic control refers to the synchronization or timing coordination of the outputs of the far-infrared heating component and the acoustic excitation component by the control component, including but not limited to simultaneous start-up, time-sharing alternation, power matching, or dynamic adjustment based on feedback, so that the two energies can form a mutually reinforcing effect in the permeation reaction chamber.

[0061] Understandably, referring to Figure 3 The device provided in this application forms a space covering the user's head through a shell assembly, providing a structural basis for constructing the penetration-enhancing reaction chamber. A flexible interface layer creates a relatively sealed penetration-enhancing reaction chamber between the device and the user's head, effectively locking in moisture in the hair styling composition by maintaining humidity balance, preventing it from drying or crystallizing during heating, and ensuring that the diffusion channels remain unobstructed during subsequent energy application. The detachable design of the flexible interface layer facilitates user replacement and cleaning after use, solving the maintenance problem of difficult-to-clean hair dye contamination in traditional devices, thus avoiding contamination of the shell assembly by the hair styling composition. Preferably, the flexible interface layer maintains a 5-15mm energy gap in the relatively sealed penetration-enhancing reaction chamber between the device and the user's head.

[0062] The far-infrared heating component radiates far-infrared energy of a specific wavelength into the penetration-enhancing reaction chamber. This energy can penetrate the flexible interface layer and act on the hair styling composition, reducing viscosity by adjusting its rheological properties and improving the fluidity and spreading ability of the active ingredients on the hair surface. The acoustic excitation component uses an all-solid-state energy array to directly generate acoustic energy through electro-deformation, avoiding wear and noise from mechanical moving parts. At the same time, it can more efficiently couple acoustic energy into the penetration-enhancing reaction chamber, stimulating an acoustic flow effect in the hair styling composition and physically pressing active ingredients such as pigments into the hair cuticle gaps.

[0063] The control components coordinate the control of far-infrared energy and acoustic energy, ensuring that the two energies are matched in time and intensity. The reduced viscosity of the far-infrared energy enhances the driving effect of the acoustic energy, while the flow generated by the acoustic energy ensures a more even distribution and heating of the hair care composition, creating a virtuous cycle. Through this coordinated control, the device can significantly improve the penetration efficiency and uniformity of the hair care composition within a safe temperature range, achieving an efficient, safe, and comfortable hair care experience.

[0064] Furthermore, the far-infrared heating component of the hair-plasticizing composition emits far-infrared wavelengths in the range of 8μm to 14μm, and the far-infrared heating component is used to maintain the working temperature of the containing space within a preset working temperature range of 38°C to 45°C; the acoustic energy frequency output by the acoustic excitation component is in a first frequency range of 2kHz to 5kHz and / or in a second frequency range of 25kHz to 50kHz.

[0065] It should be noted that the far-infrared wavelength being in the 8μm to 14μm range means that the infrared radiation generated by the far-infrared heating component is mainly concentrated in this wavelength range. This wavelength range can resonate and absorb with water molecules and organic molecules, achieving deep and uniform heating. The far-infrared heating component is used to maintain the working temperature of the containment space within a preset working temperature range of 38℃ to 45℃. This means that the output of the far-infrared heating component is adjusted by the control component to stabilize the temperature of the penetration-enhancing reaction chamber within this range. This temperature range is below the traditional heat damage threshold and is sufficient to effectively reduce the viscosity of the hair-care composition.

[0066] The first frequency range of 2kHz to 5kHz refers to the low-frequency band used to generate macroscopic disturbances. Sound waves in this band can induce large-scale media flow when propagating in viscous media. The second frequency range of 25kHz to 50kHz refers to the high-frequency band used to generate microscopic acoustic flow. Sound waves in this band are within the upper limit of human hearing or the ultrasonic range, avoiding auditory discomfort for users. The output acoustic energy frequency being within the first and / or second frequency range means that the acoustic excitation component can output low-frequency or high-frequency sound waves independently, or simultaneously output acoustic energy in both frequency bands through frequency synthesis or time-division switching.

[0067] Understandably, the far-infrared heating element utilizes a specific wavelength range of far-infrared light, enabling it to resonate and absorb with the hair styling composition and water molecules in the hair, achieving deep and uniform heating rather than surface burning. This heating method effectively reduces the viscosity of the hair styling composition within a safe temperature range, improving its rheological properties and making it easier for active ingredients to spread and move on the hair surface, creating favorable medium conditions for the subsequent physical drive of acoustic energy. The selection of this temperature range balances penetration enhancement with safety, being sufficient to activate the fluidity of the hair styling composition while avoiding scalp burns and keratin denaturation caused by high temperatures.

[0068] The acoustic excitation component employs a dual-band design with a clear division of labor and synergistic effect. The low-frequency sound waves, with their longer wavelengths and stronger penetration, generate macroscopic-scale media disturbances within the hair styling composition, ensuring uniform distribution and pre-defined flow direction, while simultaneously promoting full contact between the composition and the hair surface. The high-frequency sound waves excite stable acoustic flow effects at the microscopic scale, generating directional micro-vortices within the composition, physically pressing pigments and other active ingredients into the hair cuticle gaps.

[0069] The acoustic energy of the two frequency bands can be used individually or in combination to adapt to the penetration-enhancing needs of hair styling compositions with different viscosities and compositions, as well as different hair types. When both frequency bands are applied simultaneously, the low-frequency energy creates a macroscopic flow environment, while the high-frequency energy achieves precise microscopic driving. The synergistic effect of the two can achieve multi-scale penetration enhancement from macroscopic to microscopic, significantly improving penetration efficiency and uniformity.

[0070] Thus, the far-infrared heating component and the acoustic excitation component operate under their respective optimal parameters and are synergistically controlled by the control component, so that the thermal effect and acoustic effect enhance each other in the penetration-promoting reaction chamber, jointly achieving the efficient and safe penetration-promoting effect of the hair-beautifying composition.

[0071] Furthermore, the acoustic energy applied by the acoustic excitation component at 2 kHz to 5 kHz is used to generate macroscopic disturbances in the hair styling composition, and the acoustic energy applied by the acoustic excitation component at 25 kHz to 50 kHz is used to generate microscale acoustic flow in the hair styling composition.

[0072] It should be noted that macroscopic disturbances refer to large-scale, holistic media movement phenomena caused by the propagation of sound waves in the hair styling composition medium, including but not limited to the overall surging, tumbling, convection, and periodic deformation at the interface. Acoustic energy in the 2 kHz to 5 kHz frequency range has a long wavelength and strong penetrating power, capable of inducing macroscopic-scale media flow in viscous hair styling compositions, resulting in a holistic dynamic distribution adjustment of the hair styling composition coated on the hair surface. Microscopic-scale acoustic flow refers to the steady-state microfluidic field phenomena caused by the attenuation of sound wave energy and nonlinear interaction when high-frequency sound waves propagate in a liquid medium, including but not limited to localized microvortices formed within the medium, directional microflows near the boundary layer, and controlled movement of microparticles. Acoustic energy in the 25 kHz to 50 kHz frequency range can effectively induce such microscopic-scale acoustic flow effects in hair styling compositions, producing precise driving at the cuticle scale.

[0073] Therefore, this application achieves comprehensive control over the penetration process of hair styling compositions through the multi-scale action of dual-frequency acoustic energy without relying on chemical penetrants, significantly improving penetration efficiency and uniformity while maintaining the stability and controllability of the processing.

[0074] Furthermore, the support unit of the penetration-enhancing device of the hair styling composition includes a vibration decoupling structure with nonlinear damping characteristics for absorbing residual mechanical vibrations generated by the acoustic excitation component, thereby limiting the transmission of vibration energy to the user through the solid.

[0075] It should be noted that a vibration decoupling structure refers to a functional structure installed in the support unit to isolate vibration. Its materials include, but are not limited to, rubber, silicone, thermoplastic elastomers, polyurethane foam, or composite materials. It can constitute a local area of ​​the support unit alone or be added as an additional layer to the surface of the support unit. Nonlinear damping characteristics refer to the nonlinear variation of the damping coefficient of the vibration decoupling structure with the vibration amplitude, frequency, or magnitude of the applied force. This includes, but is not limited to, the damping coefficient increasing with increasing amplitude, exhibiting a nonlinear response with frequency, or having strain rate-dependent damping characteristics. Absorption of residual mechanical vibration generated by the acoustic excitation component refers to the vibration decoupling structure converting the residual mechanical vibration energy transmitted to the outer shell assembly and support unit during the operation of the acoustic excitation component into heat energy or other forms of energy dissipation, thereby reducing the duration and propagation of vibration. Residual mechanical vibration refers to the residual mechanical vibration energy of the acoustic excitation component during and after operation, including but not limited to the residual oscillation of the piezoelectric transducer itself, continuous vibration caused by structural resonance, and parasitic vibration generated by sound waves propagating in a solid medium. Limiting vibration energy transmission to the user through solids means using the absorption and isolation effects of vibration decoupling structures to block or significantly attenuate the propagation path of vibration energy along the support unit, shell assembly to the user's head bones and soft tissues, thereby reducing the mechanical vibration perceived by the user.

[0076] It is understandable that the acoustic excitation component generates acoustic energy through electro-deformation during operation, a process that inevitably produces some residual mechanical vibration. If this residual vibration energy is directly transmitted to the user's head through the support unit without processing, it will be efficiently conducted to the inner ear along solid media such as the skull, causing discomfort such as tinnitus, headache, or a feeling of vibration, affecting the user's tolerance for long-term wear and the user experience. Preferably, the acoustic excitation component is mounted on the shell through an elastic buffer layer, which can greatly reduce the resonance noise of the shell during actual production.

[0077] The vibration decoupling structure is located within the support unit, situated on the critical transmission path between the acoustic excitation components of the vibration source and the user. Its nonlinear damping characteristics enable it to produce differentiated absorption effects on mechanical residual vibrations of varying intensities and frequencies. When the vibration amplitude is small, the damping effect is relatively mild, not affecting the basic support function of the support unit; as the vibration amplitude increases, the damping coefficient increases accordingly, enhancing the absorption effect and effectively suppressing the propagation of strong vibrations. This nonlinear characteristic allows the vibration decoupling structure to maintain optimal vibration reduction performance under various operating conditions, while avoiding excessive damping that could affect the normal output of acoustic energy.

[0078] By absorbing residual mechanical vibrations and limiting their transmission to the user through solids, the vibration decoupling structure decouples the acoustic excitation function from the user's comfort experience. The acoustic excitation component can output acoustic energy according to the optimal penetration-enhancing requirements without reducing its workload to accommodate user tolerance; at the same time, the mechanical vibrations felt by the user are significantly suppressed, ensuring wearing comfort. This design allows the device to adapt to the needs of long-term home care scenarios while maintaining efficient penetration-enhancing performance.

[0079] The vibration decoupling structure is compatible with other functions of the adaptive suspension support mechanism. While maintaining the energy gap and penetrating the hair-like layer, the support unit achieves vibration damping through the vibration decoupling structure, allowing the same structural unit to perform multiple tasks without interference. Therefore, this application, while achieving efficient acoustic permeation, effectively solves the user discomfort problem that may be caused by mechanical residual vibration through the vibration decoupling structure, improving the overall practicality of the device and the user experience.

[0080] Preferably, this application applies acoustic energy by sweeping frequency and, combined with the specific physical structure of the permeation-promoting reaction chamber, systematically optimizes the user's auditory and physical comfort during use.

[0081] Since the first frequency range (2kHz-5kHz) output by the acoustic excitation component falls within the range of human hearing sensitivity, continuous output at a single frequency can easily lead to a standing wave effect due to the superposition of sound waves within the permeation reaction cavity, resulting in excessive local sound pressure and causing a continuous piercing sensation or tinnitus. This application uses a control component to drive the acoustic excitation component to perform frequency sweeping, causing the sound wave frequency to continuously and dynamically change within a preset range. This effectively suppresses the formation of standing waves, avoids continuous stimulation of the auditory nerve by a single frequency point, and eliminates piercing noise at its source.

[0082] Meanwhile, the penetration-enhancing reaction chamber, constructed from the outer shell, flexible interface layer, and hair surface, forms an effective acoustic shielding space. When sound wave energy penetrates the tensioned flexible interface layer, the damping system formed by the interface layer and the sealing skirt effectively filters out unnecessary high-frequency spikes and parasitic harmonics, precisely coupling the core penetration-enhancing energy into the hair styling composition. This synergistic design of physics and algorithms ensures highly efficient penetration while significantly improving user comfort during device operation.

[0083] Furthermore, the inner wall of the outer shell assembly of the hair-dyeing composition's penetration-enhancing device is provided with an energy-reflecting layer, which is a nano-silver coating or a vacuum-plated aluminum coating, used to refocus the far-infrared energy and the acoustic energy.

[0084] It should be noted that the energy reflective layer refers to a functional coating applied to or laminated onto the inner wall of the outer casing component. Its materials include, but are not limited to, nano-silver coatings or vacuum-plated aluminum coatings. These materials exhibit high reflectivity for far-infrared energy of specific wavelengths and acoustic energy of specific frequencies. Nano-silver coatings are reflective layers formed primarily of nano-sized silver particles, achieving a reflectivity of over 90% for the infrared band. Vacuum-plated aluminum coatings are thin films of metallic aluminum formed on the inner wall of the outer casing through a vacuum evaporation process, also exhibiting excellent reflective properties. Secondary focusing refers to the energy reflective layer reflecting energy emitted by the far-infrared heating component and acoustic excitation component—energy that might otherwise dissipate towards the outer casing—back into the permeation reaction chamber. This results in a more uniform energy distribution on the three-dimensional curved surface, reducing energy loss and improving energy utilization efficiency. Secondary focusing of far-infrared and acoustic energy includes, but is not limited to, directional reflection of far-infrared energy with wavelengths from 8 micrometers to 14 micrometers, and acoustic energy with frequencies from 2 kHz to 5 kHz and 25 kHz to 50 kHz, creating a more uniform energy distribution within the permeation reaction chamber.

[0085] Understandably, by setting an energy reflective layer on the inner wall of the outer casing, the dissipated energy emitted by the far-infrared heating component and the acoustic excitation component can be refocused onto the permeation-enhancing reaction chamber, significantly improving energy utilization efficiency and ensuring a more uniform field of action between far-infrared and acoustic energy on the hair surface. Simultaneously, the energy reflective layer reduces the thermal load on the outer casing, minimizing heat loss to the external environment, extending the device's lifespan, and making the energy distribution within the permeation-enhancing reaction chamber more stable and controllable, providing a superior physical environment for the synergistic effect of far-infrared radiation and acoustic energy.

[0086] Furthermore, the penetration-enhancing device of the hair-care composition further includes: A red light array, located inside the housing assembly, is used to radiate visible red light energy into the permeation-enhancing reaction chamber to improve the user's wearing comfort during device operation.

[0087] It should be noted that the red light array refers to a combination of elements disposed inside the outer casing assembly to generate visible red light radiation, including but not limited to an array structure composed of one or more light-emitting diodes (LEDs), such as medical-grade LEDs, high-power LEDs, or flexible LED arrays. Visible red light energy refers to light radiation with wavelengths in the red band of the visible spectrum, including but not limited to the range of 620 to 740 nanometers. In this embodiment, visible red light with a wavelength of 630 nanometers is preferred, as this wavelength has good biocompatibility and tissue penetration capabilities. The device's operating period refers to the entire time during which the user wears the penetration-enhancing device and activates it, including the complete cycle in which the far-infrared heating component, acoustic excitation component, and red light array are in working condition. Wearing comfort refers to the comprehensive evaluation of the user's subjective feelings during device use, including but not limited to the appropriateness of the warmth, the gentleness of the vibration, the soothing sensation in the scalp area, and the tolerance for prolonged wear. Improving the user's wearing comfort during device operation refers to improving the overall user experience through the physical effects of visible red light, including but not limited to promoting local microcirculation, regulating scalp surface temperature perception, reducing the cumulative warmth that may result from prolonged energy exposure, and creating a soothing sensory experience.

[0088] Understandably, the red light array is located inside the outer casing, alongside the far-infrared heating component and the acoustic excitation component, around the permeation-enhancing reaction chamber. The visible red light energy radiated from it can penetrate the flexible interface layer and act on the user's scalp. The red light energy is compatible with the far-infrared radiation energy and acoustic energy, without mutual interference or energy cancellation. They can work in parallel within the same permeation-enhancing reaction chamber, jointly serving the hair care process. Visible red light energy improves local microcirculation and assists in uniform heat distribution, thereby optimizing the user's experience.

[0089] It is evident that the physical effects of red light energy on the scalp area help optimize the user's subjective experience during device operation. When the device operates for extended periods, far-infrared heating may cause a certain accumulation of heat in the scalp area, while acoustic stimulation may produce subtle vibrations. The intervention of red light energy can promote local microcirculation, helping to disperse and regulate heat distribution, making the user's perception of warmth more uniform and comfortable. Simultaneously, the specific wavelength of red light itself has a gentle visual and warm sensation, which can create a positive psychological suggestion for the user, enhancing the overall user experience.

[0090] The improved wearing comfort is not independent of the penetration-enhancing effect, but rather interacts positively with the core function. When users feel more comfortable while the device is in use, they are more likely to maintain the preset treatment time and are less likely to interrupt use prematurely due to discomfort. This indirectly ensures that the synergistic effect of far-infrared energy and acoustic energy can fully exert its penetration-enhancing effect, ensuring that the penetration efficiency and uniformity of the hair styling composition meet the design goals.

[0091] The red light array, as an optional configuration, provides users with a choice to optimize comfort while maintaining full compatibility with the core technology solution. Users can choose to turn the red light function on or off according to their own sensitivity to comfort, allowing the device to adapt to the personalized needs of different user groups. Therefore, this implementation method, while achieving the core objective of efficient penetration, further optimizes the user experience, making the entire hair care process more comfortable and suitable for application scenarios with higher requirements for wearing comfort.

[0092] Furthermore, the flexible interface layer is connected to the outer shell assembly or the user's head through a fixed interface structure, wherein the fixed interface structure is selected from one or more of elastic fasteners, mechanical locking components, adhesive components, or magnetic components.

[0093] It should be noted that a fixed interface structure refers to a structural unit used to physically connect the flexible interface layer to the outer shell assembly or the user's head. Its function is to ensure that the flexible interface layer maintains a stable spatial position and shape during operation. Elastic fasteners refer to structures that achieve connection through the elastic deformation of materials, including but not limited to rubber rings, silicone rings, elastic bands, or spring clips, which fix the flexible interface layer in a predetermined position through tensile rebound force. Mechanical locking components refer to structures that achieve connection through mechanical interlocking, including but not limited to snaps, latches, buttonholes, locking hooks, or threaded connectors, which ensure connection reliability through rigid fit. Adhesive components refer to structures that achieve connection through adhesive force, including but not limited to double-sided tape, pressure-sensitive adhesive layers, hot melt adhesive, or removable adhesive stickers, which can achieve non-rigid adhesion between the flexible interface layer and the outer shell assembly or skin. Magnetic components refer to structures that achieve connection through magnetic attraction, including but not limited to the combination of permanent magnets and magnetic conductive sheets or dual magnet attraction structures, which can achieve quick disassembly and reuse. "Selected from one or more" means that the fixed interface structure can adopt a single type or a combination of multiple types mentioned above to adapt to different usage scenarios and user needs.

[0094] Understandably, by setting up various types of fixed interface structures, this device provides diverse connection options for the flexible interface layer. Elastic fasteners ensure tension and fixation of the flexible interface layer and facilitate disassembly and replacement; mechanical locking components provide highly reliable connections to meet the needs of long-term use; adhesive components achieve a gentle fit to the head, improving wearing comfort; and magnetic components facilitate quick installation, removal, and reuse. This diverse connection design allows the device to adapt to different users' operating habits and usage scenarios, while ensuring that the flexible interface layer maintains a stable spatial position and shape during operation, providing a reliable physical basis for the construction and maintenance of the permeation reaction chamber.

[0095] Furthermore, the support unit of the adaptive suspension support mechanism is provided with a sealing skirt. In the supported state, the sealing skirt presses against the edge of the positioning through hole of the flexible interface layer, so that the flexible interface layer is stretched and divided into a number of stretched and tensioned sub-interfaces by the support unit. The stretched and tensioned sub-interfaces are used to reduce the energy loss of the acoustic energy sent by the acoustic excitation component into the permeation reaction chamber.

[0096] It should be noted that a support unit refers to a component that makes physical contact with the user's head area, and its shape includes, but is not limited to, dotted protrusions, strip-shaped ribs, comb-like arrays, or elastic pads. A sealing skirt refers to an elastic extension structure located at the base of the support unit, made of materials including, but not limited to, silicone, rubber, or thermoplastic elastomers, possessing compressible deformation characteristics. The supported state refers to the working state where, when the device is worn on the user's head, the support unit is compressed and forms a stable contact with the skin or hairline. A positioning through-hole refers to a through-hole located on the flexible interface layer, used for the support unit to pass through and achieve precise alignment between the flexible interface layer and the outer shell assembly. A stretched sub-interface refers to several independent membrane areas formed between adjacent support units after the flexible interface layer is stretched and tightened by multiple support units. Each sub-interface remains taut due to the tensile force of the surrounding support units, similar to the physical form of a taut drumhead. Stretch tension refers to the stretching and unfolding of the material molecular chains of the flexible interface layer under the action of the support units, resulting in a flat state with a certain degree of tension. Reducing the energy loss of acoustic energy entering the infiltration reaction chamber refers to improving acoustic impedance matching through tensioned sub-interfaces, enabling the sound waves emitted by the acoustic excitation components to penetrate the flexible interface layer with higher efficiency, and reducing sound wave reflection and absorption caused by interface relaxation or wrinkles.

[0097] Understandably, by sealing the edge of the positioning through-hole with the skirt, the support unit not only fixes and seals the flexible interface layer but also tensions and divides it into multiple stretched sub-interfaces. These tensioned sub-interfaces are similar to a series of miniature, force-tensioned acoustic coupling membranes. When the acoustic excitation component applies acoustic energy to the penetration-enhancing reaction chamber, each sub-interface can generate effective forced vibrations, efficiently coupling and transferring acoustic energy from the air medium to the hair styling composition within the penetration-enhancing reaction chamber. Compared to a relaxed or wrinkled membrane, the tensioned sub-interfaces have superior elastic response characteristics, lower acoustic reflectivity, and lower acoustic impedance, significantly reducing energy loss during sound wave propagation across media. This ensures that more acoustic energy is used to excite the acoustic flow effect in the hair styling composition, thereby improving the penetration efficiency of active ingredients such as pigments into the hair cuticle gaps.

[0098] When using the penetration-enhancing device of the hair-dyeing composition provided in this application, it is preferable to follow the steps below for wearing to ensure precise construction of the penetration-enhancing reaction chamber and optimal energy effect: First, the flexible interface layer is installed onto the outer shell assembly. Specifically, the elastic fastening ring at the edge of the flexible interface layer is held and stretched before being fitted onto the fixed interface structure inside the outer shell assembly. The fixed interface structure includes, but is not limited to, positioning posts, slots, or magnetic bases. After the elastic fastening ring is fitted, it is tightened and fixed by its own elastic recoil force, causing the flexible interface layer to be evenly stretched and unfolded, forming a flat state similar to a drumhead. At this point, the pre-set positioning through holes on the flexible interface layer initially correspond in position to the support units of the adaptive suspension support mechanism inside the outer shell assembly.

[0099] Then, the outer shell assembly with the flexible interface layer already installed is placed on the user's head. During the wearing process, several support units of the adaptive suspension support mechanism pass through the corresponding positioning through holes on the flexible interface layer and gradually come into contact with the user's head area. Since the flexible interface layer has been tensioned and fixed to the outer shell assembly, the process of the support units passing through the positioning through holes naturally achieves precise alignment between the openings on the membrane and the support units inside the machine, ensuring that each support unit passes through the preset positioning through hole and avoiding assembly deviations caused by hole misalignment.

[0100] Finally, adjust the outer shell assembly to a comfortable position, ensuring stable contact between the support unit and the user's head area. At this point, the sealing skirt on the support unit elastically deforms under pressure, tightly pressing against the edge of the positioning through-hole to form a dynamic sealing structure. Simultaneously, the elastic fastening ring at the edge of the flexible interface layer is fitted onto the user's head, allowing the flexible interface layer, supported by the support unit, to form a permeation-enhancing reaction chamber with a preset energy gap between it and the hair surface. This chamber, due to the established sealing structure, possesses the ability to maintain a high-humidity environment.

[0101] Understandably, this wearing process, through the sequence of "first applying the film, then wearing the device, and finally sealing," achieves two core functions: first, the cooperation between the elastic fastening ring and the fixed interface structure ensures precise alignment between the positioning holes of the flexible interface layer and the support unit, allowing acoustic energy to penetrate the flexible interface layer and act on the hair styling composition with minimal loss; second, the sealing skirt, under the support state, compresses and maintains the airtightness of the penetration-enhancing reaction chamber, providing a stable high-humidity physical environment for the synergistic effect of far-infrared radiation energy and acoustic energy. This wearing process design fully considers the ease of operation and repeatability in home scenarios, possessing excellent industrial practicality and user experience.
