Hair-growing hair mask

Abstract

The invention provides a hair-growing hair mask. The hair-growing hair mask comprises an effective main body part, and in the direction perpendicular to the thickness of the effective main body part, the effective main body part comprises an inner layer and an outer layer which is arranged on the periphery of the inner layer in a surrounding mode and abuts against the inner layer. The inner layer comprises a first hydrogel and a first cacumen biotae extract, and the outer layer comprises a second hydrogel and a second cacumen biotae extract. The mass percentage of the second cacumen biotae extract in the outer layer is greater than that of the first cacumen biotae extract in the inner layer. The mass percentage of the second cacumen biotae extract in the outer layer is 20-50%, and the mass percentage of the first cacumen biotae extract in the inner layer is 10-25%. When the hair-growing hair mask is used, the inner layer is attached to the position where hair growth is needed, the cacumen biotae extract of the outer layer can permeate into the inner layer due to the fact that the concentration difference exists between the cacumen biotae extract of the outer layer and the cacumen biotae extract of the inner layer, then the cacumen biotae extract is supplemented for the inner layer, and the effective use time of the hair-growing hair mask is prolonged.

DETAILED DESCRIPTION

[0019] One embodiment of the present invention provides a hair growth mask. The hair growth mask comprises an active body portion. In a direction perpendicular to the thickness of the active body portion, the active body portion comprises an inner layer and an outer layer disposed around and abutting the inner layer. The inner layer comprises a first hydrogel and a first Platycladus orientalis leaf extract distributed within the first hydrogel. The outer layer comprises a second hydrogel and a second Platycladus orientalis leaf extract distributed within the second hydrogel. The mass percentage of the second Platycladus orientalis leaf extract in the outer layer is greater than the mass percentage of the first Platycladus orientalis leaf extract in the inner layer. The mass percentage of the second Platycladus orientalis leaf extract in the outer layer is 20%-50%, while the mass percentage of the first Platycladus orientalis leaf extract in the inner layer is 10%-25%.

[0020] In this embodiment, the structure of the hair growth mask is designed to effectively extend the effective use time of the hair growth mask. For example, when using the hair growth mask, the inner layer is attached to the area where hair growth is required. Due to the concentration difference between the Platycladus orientalis leaf extract in the outer and inner layers, the Platycladus orientalis leaf extract in the outer layer can penetrate into the inner layer, thereby replenishing the Platycladus orientalis leaf extract in the inner layer and extending the effective use time of the hair growth mask.

[0021] Alternatively, the mass percentage of the first Platycladus orientalis leaf extract in the inner layer can be 10%, 13%, 15%, 18%, 20%, 23%, 25%, etc. The mass percentage of the second Platycladus orientalis leaf extract in the outer layer can be 20%, 25%, 30%, 35%, 40%, 45%, 50%, etc.

[0022] In some embodiments, the inner layer also includes a first excipient distributed in the first hydrogel, and the first excipient includes the following components in parts by weight: 0.1-10 parts of Polygonum multiflorum root extract, 0.1-3 parts of Carthamus tinctorius extract, 0.1-3 parts of Ligustrum lucidum fruit extract, 0.1-3 parts of Cordyceps sinensis extract, 0.1-3 parts of Black Ganoderma lucidum extract, 0.1-3 parts of Chuanxiong root extract, 0.1-2 parts of Angelica sinensis root extract, 0.1-1 parts of ginseng root extract, and 0.01-1 parts of ginsenosides.

[0023] In some embodiments, the outer layer also includes a second excipient distributed in the second hydrogel, and the second excipient includes the following components in parts by weight: 0.1-10 parts of Polygonum multiflorum root extract, 0.1-3 parts of Carthamus tinctorius extract, 0.1-3 parts of Ligustrum lucidum fruit extract, 0.1-3 parts of Cordyceps sinensis extract, 0.1-3 parts of Black Ganoderma lucidum extract, 0.1-3 parts of Chuanxiong root extract, 0.1-2 parts of Angelica sinensis root extract, 0.1-1 parts of Ginseng root extract, and 0.01-1 parts of ginsenosides.

[0024] Through the synergistic combination of Platycladus orientalis leaf extract, Polygonum multiflorum root extract, Carthamus tinctorius flower extract, Ligustrum lucidum fruit extract, Cordyceps sinensis extract, Ganoderma lucidum extract, Ligustrum lucidum root extract, Angelica sinensis root extract, Ginseng root extract, and ginsenosides, the hair follicles can maintain a good metabolic environment, promote the proliferation of hair follicle cells, reduce the amount of oil produced on the scalp, further promote hair growth, reduce the risk of hair loss again, and further enhance the hair growth effect of the hair mask.

[0025] Among them, Platycladus orientalis leaf extract: rich in flavonoids, terpenes and other active ingredients, can effectively dilate scalp blood vessels, improve blood circulation of hair follicles, ensure that hair follicle cells can obtain oxygen and nutrients in a timely and sufficient manner, and lay the foundation for hair growth.

[0026] Polygonum multiflorum root extract: can precisely act on hair follicle stem cells, regulate endocrine signaling pathways, help hair follicles smoothly transition from the resting phase to the growth phase, effectively stabilize hair growth, and reduce the probability of hair loss.

[0027] Safflower Extract: Contains powerful blood-activating and blood-stasis-removing ingredients such as safflower yellow pigment, which can quickly eliminate blood stasis accumulation around hair follicles, reduce inflammatory response, restore the hair follicle microenvironment to a healthy state, and further reduce the risk of hair loss.

[0028] Ligustrum lucidum fruit extract: rich in antioxidants, it can effectively remove free radicals in hair follicle cells, protect the integrity of cell membranes, resist the damage of oxidative stress to hair follicle cells, ensure that the normal physiological functions of hair follicles are not disturbed, and continue to consolidate the anti-hair loss effect of the composition.

[0029] Cordyceps sinensis extract: It contains a variety of rare nutrients such as cordycepin and cordyceps polysaccharides. It has excellent immune regulation ability, can strengthen the local immune defense line of hair follicles, effectively resist the invasion of bacteria and fungi caused by low immunity, and prevent hair follicle infection, atrophy and other adverse conditions.

[0030] Black Ganoderma Extract: Rich in active ingredients such as Ganoderma polysaccharides and triterpenes, it can deeply participate in the signal transduction network regulation of hair follicle cells, stimulate cell proliferation and differentiation potential, repair and reshape damaged hair follicle structure, effectively stabilize the hair follicle environment, and prevent hair loss.

[0031] Chuanxiong root extract: With its unique combination of volatile oils and alkaloids, it can activate blood circulation and promote qi circulation, synergistically optimize the blood circulation of the scalp, and cooperate with other ingredients to continuously deliver nutrients to the hair follicles, ensuring smooth and unimpeded hair follicle metabolism, keeping the hair follicles healthy, and reducing hair loss problems.

[0032] Angelica root extract: Angelica is an important blood tonic, and its root extract can both replenish blood and invigorate blood circulation, precisely providing hair follicles with the necessary nutrients for growth, promoting healthy hair growth, and injecting continuous power into the battle against hair loss.

[0033] Ginseng root extract: It can improve the vitality of hair follicle cells as a whole, enhance their efficiency in nutrient absorption and utilization, and buffer the negative effects of external pressure on hair follicles, protecting the health of hair follicles in all aspects.

[0034] Ginsenosides: directly participate in regulating the proliferation and differentiation rhythm of hair follicle cells, optimize cell metabolism process, and promote hair growth and stability.

[0035] It is understood that the extracts mentioned above may be commercially available extracts. For example, they may be extracts obtained by solvent extraction. Alternatively, the solvent may be anhydrous ethanol.

[0036] As some optional embodiments of the components in the first auxiliary material and the second auxiliary material, a brief description is given below. It is understood that the mass parts of the components in the first auxiliary material and the second auxiliary material can be independently selected from the following examples.

[0037] The weight proportions of the first and second excipients, the extract of the root of Polygonum multiflorum, can be independently selected from 0.1 parts, 0.5 parts, 1 parts, 5 parts, 10 parts, etc.

[0038] The mass parts of the safflower flower extract of the first excipient and the second excipient can be independently selected from 0.1 part, 0.3 part, 0.5 part, 0.8 part, 1 part, 1.5 parts, 2 parts, 2.5 parts, 3 parts, etc.

[0039] The weight parts of the first auxiliary material and the second auxiliary material Ligustrum lucidum fruit extract can be independently selected from 0.1 parts, 0.3 parts, 0.5 parts, 0.8 parts, 1 parts, 1.5 parts, 2 parts, 2.5 parts, 3 parts, etc.

[0040] The mass parts of the Cordyceps sinensis extract of the first auxiliary material and the second auxiliary material can be independently selected from 0.1 parts, 0.3 parts, 0.5 parts, 0.8 parts, 1 part, 1.5 parts, 2 parts, 2.5 parts, 3 parts, etc.

[0041] The weight proportions of the black ganoderma extract of the first auxiliary material and the second auxiliary material can be independently selected from 0.1 part, 0.3 part, 0.5 part, 0.8 part, 1 part, 1.5 parts, 2 parts, 2.5 parts, 3 parts, etc.

[0042] The weight portions of the Chuanxiong root extract of the first excipient and the second excipient can be independently selected from 0.1 part, 0.3 part, 0.5 part, 0.8 part, 1 part, 1.5 parts, 2 parts, 2.5 parts, 3 parts, etc.

[0043] The weight portions of the angelica root extract of the first auxiliary material and the second auxiliary material can be independently selected from 0.1 parts, 0.3 parts, 0.5 parts, 0.8 parts, 1 part, 1.5 parts, 2 parts, etc.

[0044] The mass parts of the ginseng root extract of the first auxiliary material and the second auxiliary material can be independently selected from 0.1 part, 0.3 part, 0.5 part, 0.8 part, 1 part, etc.

[0045] The weight percentages of ginsenosides of the first auxiliary material and the second auxiliary material can be independently selected from 0.01 part, 0.03 part, 0.05 part, 0.08 part, 1 part, etc.

[0046] It is understandable that the mass fractions of each component in the first auxiliary material and the second auxiliary material can also be selected in other appropriate ranges within the mass fraction ranges listed herein.

[0047] In some embodiments, the mass percentage of the second excipient in the outer layer is greater than the mass percentage of the first excipient in the inner layer. In this case, the second excipient in the outer layer can supplement the inner layer, further extending the effective use time of the hair growth mask.

[0048] Optionally, the mass percentage of the second auxiliary material in the outer layer is 8%-15%. For example, the mass percentage of the second auxiliary material in the outer layer can be 8%, 9%, 10%, 11%, 12%, 13%, 14%, 15%, etc.

[0049] Optionally, the mass percentage of the first auxiliary material in the inner layer is 2%-5%. For example, the mass percentage of the first auxiliary material in the inner layer can be 2%, 2.5%, 3%, 3.5%, 4%, 4.5%, 5%, etc.

[0050] In some embodiments, the inner layer is circular and the outer layer is annular. This can make the contact surface between the inner and outer layers smoother, which is conducive to the smoother and more sufficient replenishment of the Platycladus orientalis leaf extract and excipients in the outer layer into the inner layer, further improving the hair growth effect of the hair growth mask.

[0051] Optionally, the ratio of the width of the outer layer to the diameter of the inner layer is 0.4-0.9. In this case, the Platycladus orientalis leaf extract and excipients in the outer layer can be better adapted to the inner layer in terms of dosage, so that the Platycladus orientalis leaf extract and excipients in the outer layer can better exert their efficacy. For example, if the ratio of the width of the outer layer to the diameter of the inner layer is too small, it is difficult for the Platycladus orientalis leaf extract and excipients in the outer layer to fully supplement the inner layer. If the ratio of the width of the outer layer to the diameter of the inner layer is too large, it will cause waste of the Platycladus orientalis leaf extract and excipients in the outer layer.

[0052] It can be understood that the width of the outer layer represents the difference between the radius of the outer circle and the radius of the inner circle of the ring.

[0053] Furthermore, the ratio of the width of the outer layer to the diameter of the inner layer may be 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, etc.

[0054] Furthermore, the width of the outer layer is 0.5-5 cm. For example, the width of the outer layer can be 0.5 cm, 1 cm, 1.5 cm, 2 cm, 2.5 cm, 3 cm, 3.5 cm, 4 cm, 4.5 cm, 5 cm, etc.

[0055] In some embodiments, the first hydrogel includes a first hydrophilic polymer material and a first cross-linking agent; the first hydrophilic polymer material includes sodium alginate, and the first cross-linking agent includes calcium chloride.

[0056] The second hydrogel includes a second hydrophilic polymer material and a second cross-linking agent; the second hydrophilic polymer material includes one or more of polyacrylamide and polyvinyl alcohol, and the second cross-linking agent includes glutaraldehyde.

[0057] Sodium alginate is a natural polysaccharide with a wide range of sources and excellent biocompatibility and biodegradability. In the presence of calcium ions, sodium alginate can rapidly form a gel, facilitating the preparation of a hair growth mask. Furthermore, sodium alginate possesses certain antibacterial properties, which can reduce the risk of hair follicle infection, helping to maintain a healthy environment for hair follicles and further enhancing the hair growth effect of the hair growth mask. Calcium chloride can undergo an ionic crosslinking reaction with the carboxyl groups in sodium alginate to form a gel, thereby forming a relatively stable first hydrogel.

[0058] Polyacrylamide has good water absorption and biocompatibility, and can form a stable hydrogel structure. The amide groups on its molecular chain can form hydrogen bonds with water molecules, increasing the water retention of the hydrogel skeleton. In addition, polyacrylamide also has a certain viscoelasticity, which can adapt to the shape changes of the hair growth area and provide good fit. Polyvinyl alcohol is non-toxic, biodegradable, and has good film-forming properties and mechanical strength. The properties of the hydrogel can be adjusted by blending or cross-linking with polyacrylamide. Glutaraldehyde can undergo cross-linking reactions with amino groups and other groups in the second hydrophilic polymer material to form a stable three-dimensional network structure, thereby forming a relatively stable second hydrogel.

[0059] In some embodiments, the mass percentage of the first cross-linking agent to the first hydrophilic polymer material is 0.2%-0.8%. For example, the mass percentage of the first cross-linking agent to the first hydrophilic polymer material can be 0.2%, 0.3%, 0.4%, 0.7%, 0.8%, etc.

[0060] In some embodiments, the mass percentage of the second cross-linking agent to the second hydrophilic polymer material is 1%-3%. For example, the mass percentage of the second cross-linking agent to the second hydrophilic polymer material can be 1%, 1.5%, 2%, 2.5%, 3%, etc.

[0061] Another embodiment of the present invention provides a method for preparing the above-mentioned hair growth mask. The preparation method comprises the following steps:

[0062] S101: mixing a first hydrophilic polymer material and a second hydrophilic polymer material with water to obtain a first polymer solution and a second polymer solution, respectively.

[0065] S104: placing a second hydrogel precursor solution on the periphery of the inner layer, cross-linking and shaping, to obtain an outer layer, thereby obtaining a hair growth membrane.

[0066] Optionally, a first auxiliary material may be added when preparing the first hydrogel precursor solution, and a second auxiliary material may be added when preparing the second hydrogel precursor solution.

[0067] Optionally, during cross-linking and shaping in S103, a first cross-linking agent is added to the first hydrogel precursor solution. During cross-linking and shaping in S104, a second cross-linking agent is added to the second hydrogel precursor solution.
