[0028] <First Embodiment>

[0029] First, the hair dryer of the first embodiment will be described.

[0030] Figure 1 It is a perspective view showing the hair dryer of the first embodiment. Figure 2 It is Figure 1 A side view in which the front end side of the hair dryer shown is in a separated state. Figure 3 It is Figure 1 An exploded perspective view of the hair dryer shown. Figure 4 It is Figure 1 A top view of the lower main body shown. Figure 5 It is Figure 1 A bottom view of the upper main body shown. Figure 6 It is Figure 1 A longitudinal sectional view of the upper main body shown. Figure 7 It is a view showingFigure 1 Block diagram of the structure of the hair styling device shown

[0031] In addition, in the following description, Figures 1 to 3 and Figure 6 the left side in Figure 4 and Figure 5 is also described as the "front end side", and the right side is also described as the "base end side". Also, Figure 2 and Figure 6 the lower side in Figure 4 is also described as the "front end side", and the upper side is also described as the "base end side". And, Figure 5 the upper side in

[0032] Figure 1 is also described as the "upper side", and the lower side is also described as the "lower side".

[0033] In the hair styling device 1 (penetration treatment method), the lower main body 2 and the upper main body 3 are brought closer, vibrations are applied to the hair in a liquid agent state by the vibration mechanism 21, and the hair is heated by the heating mechanism 31 at the same time. Thereby, the liquid agent can be smoothly and sufficiently penetrated into the hair.

[0034] The lower main body 2 has: a vibration mechanism 2I; and a lower housing (first housing) 22 that houses and supports the vibration mechanism 21. And, the lower housing 22 includes: a lower shell 221; and a lower cover 222 that closes the upper opening of the lower shell 221.

[0035] The constituent material of the lower housing 22 (lower shell 221 and lower cover 222) is not particularly limited, and examples thereof include hard resin materials such as polycarbonate, polypropylene, polystyrene, and ABS resin.

[0036] As Figure 3 and Figure 4 shown, an opening 222a is formed on the front end side of the lower cover 222. A vibration plate 211 is inserted into the opening 222a through a vibration plate bracket 210. That is, the lower cover 222 (lower housing 22) supports the vibration plate 211.

[0037] The size of the vibration plate 211 in a top view (top-down view) is not particularly limited, and is preferably 1000 mm 22500 mm or more 2 to a level of 1200 mm or less, more preferably 1200 mm 2 2300 mm or more 2 to a level of 2300 mm or less. If the vibrating plate 211 is of this size, the contact area with the hair can be fully ensured during the impregnation treatment.

[0038] Moreover, a gasket (sealing member) (not shown) is disposed between the vibrating plate holder 210 and the lower cover 222 to ensure the liquid tightness of the lower housing 22.

[0039] A vibrator 212 in contact with the vibrating plate 211 is provided inside the lower housing 22. A vibration control substrate 23, a radiator 24 for cooling the vibrator 212, and other gaskets (sealing members) (not shown) are provided on the proximal end side of the vibrator 212. In the present embodiment, the vibration mechanism 21 is composed of the vibrating plate 211 and the vibrator 212.

[0040] Therefore, in the present embodiment, vibration is applied to the hair by the vibrator 212 via the vibrating plate 211. With this configuration, it is easy to uniformly apply vibration to the hair. Therefore, the efficiency of the liquid agent permeating into the hair can be improved, and uneven permeation can be better prevented.

[0041] The vibration control substrate 23 is used to set the vibration conditions (such as vibration frequency) of the vibrator 212 (vibrating plate 211).

[0042] There is no particular limitation on the constituent material of the vibrating plate 211, and metal materials and ceramic materials can be cited. Among them, the constituent material of the vibrating plate 211 is preferably a metal material, more preferably stainless steel, aluminum, or aluminum alloy, and still more preferably stainless steel. The vibrating plate 211 made of stainless steel not only has excellent corrosion resistance, but also has a smooth upper surface and good slidability against the hair, so it is preferred. Therefore, damage to the hair can be reduced.

[0043] In addition, the constituent material of the vibrating plate holder 210 can be the same as or different from the constituent material of the vibrating plate 211.

[0044] The surface roughness, i.e., the arithmetic mean height Ra, of the upper surface (the surface on the side in contact with the hair) of the vibrating plate 211 is preferably in the range of 0.2 μm or more and 6.3 μm or less, more preferably in the range of 1.6 μm or more and 3.2 μm or less. If the surface roughness of the upper surface of the vibrating plate 211 is small enough, the slidability of the hair on the upper surface of the vibrating plate 211 can be further improved. In addition, the arithmetic mean height Ra is a value defined in JIS B0601:2001.

[0045] Further, it is preferable that the vibrating plate 211 has an oxide coating film on its upper surface (the surface on the side in contact with the hair). By forming an oxide coating film on the upper surface of the vibrating plate 211, it is convenient to adjust the surface roughness of the upper surface of the vibrating plate 211 to the above range.

[0046] Moreover, it is preferable that the oxide coating film is black or dark-colored. Thus, by absorbing the heat from the heating mechanism 31, the heating effect on the hair can be improved. Also, the aesthetic property of the vibrating plate 211 can be enhanced.

[0047] Such an oxide coating film can be formed relatively simply, for example, by anodic oxidation treatment using a treatment liquid containing a black pigment or a dark-colored pigment.

[0048] An oxide coating film similar to that can be formed on the upper surface of the vibrating plate holder 210. Additionally, it is preferable to form a film containing Black Silica on the upper surface of the vibrating plate holder 210. By forming such a film, damage to the hair can be reduced.

[0049] It is also preferable that the vibrating plate 211 has, on its upper surface (the surface on the side in contact with the hair), a coating film instead of the above-mentioned oxide coating film, and this coating film can improve the sliding property of the hair sliding on the vibrating plate 211. By forming such a coating film, the sliding property of the hair on the upper surface of the vibrating plate 211 can be further improved.

[0050] In this case, it is preferable that the hardness of the coating film is higher than that of the vibrating plate 211. In this case, the sliding property of the hair on the upper surface of the vibrating plate 211 can be further improved. When the vibrating plate 211 is made of stainless steel, it is preferable to form a coating film made of titanium. The coating film made of titanium can be formed, for example, on the upper surface of the vibrating plate 211 by a vapor deposition method such as evaporation or sputtering.

[0051] As described above, from the viewpoint of optimizing the hair sliding property, it is preferable that the surface roughness, i.e., the arithmetic mean height Ra, of the upper surface of the vibrating plate 211 is as small as possible. If processed by grinding, it is likely to result in a relatively high cost. Here, it is preferable that the vibrating plate 211 is made of stainless steel or ceramic, or a fluororesin (such as tetrafluoroethylene) coating film or a black stainless steel coating film is formed. Thus, a vibrating plate 211 with a smooth upper surface can be produced at a relatively low cost.

[0052] Furthermore, the hair beauty device 1 is provided with a pair of hairbrush parts 5 protruding laterally at the front end side of the lower case 221 (the position corresponding to the vibrating plate 211). Each hairbrush part 5 includes a plurality of comb teeth 51, and hair can pass through between the comb teeth 51.

[0053] In a state where the lower main body 2 (the first housing) and the upper main body 3 (the second housing) are close to each other, hair is clamped and made to slide through, so that the hair can be guided and passed through in a bundled state between the lower main body 2 and the upper main body 3. That is, the hairbrush part 5 constitutes a guiding part, which guides the hair at the gap between the lower main body 2 and the upper main body 3 in the close state.

[0054] And, as Figure 3 and Figure 4 shown, at the base end side of the lower housing 221, there are provided: a concave part 223; and a cylindrical part 224, which surrounds the opening of the concave part 223. Inside the concave part 223, a cylindrical sealing member 25 and a spiral spring 26 are arranged.

[0055] The sealing member 25 is connected to the lower main body 2 and the upper main body 3 to ensure liquid tightness. Wiring for electrically connecting the electrical components in the lower main body 2 and the electrical components in the upper main body 3 passes through the sealing member 25.

[0056] The spiral spring 26 is set to contact both the lower main body 2 and the upper main body 3. When the lower main body 2 and the upper main body 3 approach each other, the spiral spring 26 is in a compressed state and applies a force in the direction of separating the lower main body 2 and the upper main body 3.

[0057] At the base end part of the lower main body 2, the upper main body 3 is movably connected to the lower main body 2.

[0058] The upper main body 3 has: a heating mechanism 31; and an upper housing (the second housing) 32, which houses and supports the heating mechanism 31. And, the upper housing 32 includes: an upper shell 321; and an upper cover 322, which closes the lower opening of the upper shell 321.

[0059] The constituent material of the upper housing 32 (the upper shell 321 and the upper cover 322) is not particularly limited. For example, hard resin materials such as polycarbonate, polypropylene, polystyrene, and ABS resin can be cited.

[0060] As Figure 5 shown, an opening part 322a is formed at the front end side of the upper cover 322. A light emitting part 310 is provided at the opening part 322a, and a heating plate 311 is embedded inside the light emitting part 310. A thin film heater (heat source) 312 is arranged above the heating plate 311, and the thin film heater 312 has a heating wire built in. That is, the upper cover 322 (the upper housing 32) supports the thin film heater 312. And, in this embodiment, the heating mechanism 31 is composed of the heating plate 311 and the thin film heater 312.

[0061] And, as Figure 6As shown, a gasket (sealing component) 323 is disposed between the vibration plate bracket 210 and the lower cover 222 to ensure the liquid tightness of the upper housing 32.

[0062] The light emitting unit 310 may be composed of a transparent (colorless transparent, colored transparent or semi - transparent) support plate and a light source (such as an LED) fixed (supported) on the upper surface of the support plate. The light source may use only one color alone or a combination of multiple colors.

[0063] As the constituent material of the heating plate 311, the same constituent material as that of the vibration plate 211 can be cited, and stainless steel is preferred. The heating plate 311 made of stainless steel has a high heat transfer rate, so it is preferred. In this case, similarly to the above, it is preferred to form an oxide film (especially a black or dark - colored oxide film) on the lower surface of the heating plate 311.

[0064] Specifically, the film heater 312 can be obtained by forming a polyamide embedded with a heating wire into a film shape. By using the film heater 312, the heating to the target heating temperature can be accelerated. As a result, the time required for the impregnation treatment can be shortened.

[0065] Preferably, the resistance value of the film heater 312 is in the range of 2Ω or more and 20Ω or less, more preferably in the range of 4Ω or more and 17Ω or less, and further preferably in the range of 6Ω or more and 14Ω or less. If the film heater 312 has such a resistance value, the above - mentioned effect can be further enhanced.

[0066] In addition, a ceramic heater, a light source for heating (such as a halogen lamp for heating), etc. can be used as the heat source instead of the film heater 312.

[0067] Inside the upper housing 32, a light emission control substrate 33 and a power supply 34 are provided above the film heater 312. By using the film heater 312 as the heat source, the space inside the upper housing 32 can be fully ensured, so that the light emission control substrate 33 and the power supply 34 can be arranged in this space. As a result, the miniaturization of the hair beauty device 1 can be achieved.

[0068] The light emission control substrate 33 is used to set the light emission conditions of the light source (such as the selection of the light - emitting light source, the light - emitting pattern).

[0069] The power supply can be composed of primary batteries such as dry batteries, solar cells, fuel cells and secondary batteries such as lithium batteries, etc. And by arranging the power supply with a relatively large mass on the front - end side inside the upper housing 32, the operation of bringing the upper main body 3 closer to the lower main body 2 is facilitated.

[0070] A main control substrate 30, an interface portion 39 and other gaskets (sealing components) not shown are provided on the base - end side inside the upper housing 32.

[0071] The interface portion 39 is open to the outside at the proximal end of the upper main body 3. When the power source is a secondary battery, charging is performed by connecting to the interface portion of the charging device at the interface portion 39.

[0072] And, as Figure 5 shown, at the proximal end side of the upper shell 321, there are provided: a recess 323; and a cylindrical portion 324 surrounding the opening of the recess 323. Inside the recess 323, there are provided: a fitting portion 35 for fitting the sealing member 25; and a spring seat 36 for the coil spring 26.

[0073] In the assembled state of the hair dryer 1, the cylindrical portion 324 is inserted into the recess 223 and the cylindrical portion 224.

[0074] As Figure 1 and Figure 6 shown, on the upper surface of the upper shell 321, there are provided two operation buttons 37, 38. For example, the operation button 37 is a button for turning on / off the power, and the operation button 38 is a button for selecting and determining the working mode of the hair dryer 1. In addition, the operation buttons 37, 38 may also have other functions respectively.

[0075] In addition, an operation button for setting the vibration frequency, an operation button for setting the heating temperature, etc. may also be provided.

[0076] The lower housing (first housing) 22 of the lower main body 2 and the upper housing (second housing) 32 of the upper main body 3 are movably connected by a hinge portion 4. That is, the proximal end portion of the lower housing 22 (the end portion opposite to the vibration plate 211) and the proximal end portion of the upper housing 32 (the end portion opposite to the thin film heater 312) are movably connected.

[0077] Specifically, as Figures 3 to 5 shown, at the proximal end portion of the lower cover 222, there are provided a pair of circular ring-shaped portions 41 opposed in the short side direction. On the other hand, at the proximal end portion of the upper cover 322, there are provided a pair of circular ring-shaped portions 42 opposed in the short side direction. The pair of circular ring-shaped portions 41 and the pair of circular ring-shaped portions 42 are aligned, the shaft member 43a is passed through the through holes of the circular ring-shaped portions 41, 42, and the fixing member 43b is installed at its end portion. Thus, the hinge portion 4 can be formed, and the lower main body 2 and the upper main body 3 can be movably connected.

[0078] Next, the electrical structure of the hair dryer 1 will be described.

[0079] As Figure 7 shown, the vibration control substrate 23, the thin film heater 312, the light emission control substrate 33, the power source 34, and the interface portion 39 are electrically connected to the main control substrate 30.

[0080] Further, a vibrator 212 is connected to the vibration control substrate 23, and a light-emitting unit 310 is connected to the light-emitting control substrate 33.

[0081] The main control substrate 30 incorporates an arithmetic element 301 and a storage element 302. Additionally, the vibration control substrate 23 and the light-emitting control substrate 33 may also incorporate arithmetic elements and storage elements respectively.

[0082] The arithmetic element 301 is constituted by, for example, a CPU (Central Processing Unit), an MPU (Micro Processing Unit), etc. The arithmetic element 301 realizes various functions related to the hair beauty device 1 by reading a preset program stored in the storage element 302. That is, the information processing realized by the software stored in the storage element 302 is specifically realized through the arithmetic element 301.

[0083] In addition, the arithmetic element 301 is not limited to a single one, and multiple arithmetic elements 301 can also be provided according to each function. Additionally, it can also be a combination of these functions. In particular, the arithmetic element 301 related to the vibration control of the vibrator 212 needs to be separately provided from the arithmetic element 301 for the heating control of the thin-film heater 312.

[0084] The storage element 302 is used to store various information defined by the above description. It can be implemented, for example, in the form of a storage device such as a solid-state drive (SSD) that stores various programs, etc. related to the hair beauty device 1 executed by the arithmetic element 301, or a memory such as a random access memory (RAM) that stores temporarily required information (arguments, arrays, etc.) related to program operations.

[0085] Moreover, the storage element 302 stores various programs, variables, etc. related to the hair beauty device 1 executed by the arithmetic element 301.

[0086] When using this hair beauty device 1 (when implementing the penetration treatment method), the hair in a liquid agent state is placed between the vibration plate 211 and the heating plate 311 (thin-film heater 312), and the vibrator 212 applies vibration to the hair via the vibration plate 211, while heating the hair with the thin-film heater 312 through the heating plate 311. In this way, the liquid agent can be smoothly and sufficiently penetrated into the hair.

[0087] At this time, the vibration frequency is set to be 0.8 MHz or more and 1.5 MHz or less, preferably 0.9 MHz or more and 1.4 MHz or less, and more preferably 1 MHz or more and 1.3 MHz or less. By setting the vibration frequency within the above range, the efficiency of the liquid agent penetrating into the hair can be further improved.

[0088] Regarding the output value of vibration, preferably, the vibration plate 211 has a degree of 0.05 W or more and 0.2 W or less per unit area [cm 2 , more preferably 0.07 W or more and 0.17 W or less, and still more preferably 0.09 W or more and 0.14 W or less. In this case, the vibration uniformity of the entire vibration plate 211 can be improved. Therefore, the penetration of the liquid agent into the hair is less likely to be uneven.

[0089] In addition, the heating temperature is set to a degree of 55°C or more and 100°C or less, preferably 60°C or more and 95°C or less, and more preferably 65°C or more and 90°C or less. By setting the heating temperature within the above range, the efficiency of the liquid agent penetrating into the hair can be further improved.

[0090] The above conditions apply to the case of executing the penetration mode in which the liquid agent penetrates into the hair. In addition, after the penetration mode, or independently of the penetration mode, in the perming mode in which the hair is clamped at a high temperature, based on the vibration of the vibration plate 211 under the above conditions, preferably, the heating temperature of the heating plate 311 is set at 80°C or more and 200°C or less.

[0091] In addition, in the perming mode, it can be used for the following purposes: A: straightening curly hair; B: hair care; C: ordinary perming, etc.

[0092] A: straightening curly hair

[0093] In this case, first, the chemical bonds of the components in the curly hair are cut by applying the liquid agent 1 to the hair. Then, after rinsing the liquid agent 1 from the hair, the hair is dried. Then, the lower main body 2 and the upper main body 3 of the hair styling device 1 set to the perming mode are used to clamp the hair and clamp it at a high temperature. Finally, the liquid agent 2 is applied to the hair and left standing, thereby re-bonding the chemical bonds of the components in the hair in a straight-stretched state. In addition, when leaving it standing finally, the lower main body 2 and the upper main body 3 of the hair styling device 1 set to the penetration mode can also be used to clamp the hair for this purpose.

[0094] Examples of the agents used include QUOLINE (manufactured by ARIMINO Co., Ltd.), NeoLiscio (manufactured by MILBON Co., Ltd.), etc.

[0095] B: hair care

[0096] In this case, first, liquid agent 1 is applied to the hair. Then, the lower body 2 and the upper body 3 of the hair beauty device 1 set to the soaking mode are used to clamp the hair, thereby soaking the liquid agent 1 into the hair. Then, the liquid agent 1 is rinsed off the hair. Next, liquid agent 2 is applied to the hair. Then, the lower body 2 and the upper body 3 of the hair beauty device 1 set to the soaking mode are used to clamp the hair, thereby soaking the liquid agent 2 into the hair. Then, the hair is dried. Finally, the lower body 2 and the upper body 3 of the hair beauty device 1 set to the hair perming mode are used to clamp the hair and press it at a high temperature. Thereby, the binding of the agent soaked into the hair can be strengthened.

[0097] Examples of the agent used include BALANCER (manufactured by ARIMINO SLIM Co., Ltd.), SCIENCEAQUA (manufactured by S-AQUA Co., Ltd.), etc. In addition, in some cases, the agent may not be divided into liquid agent 1 and liquid agent 2, and only one agent may be used.

[0098] <Second Embodiment>

[0099] Next, the hair beauty device of the second embodiment will be described.

[0100] Hereinafter, for the hair beauty device 1 of the second embodiment, only the aspects different from the hair beauty device 1 of the first embodiment described above will be described, and the same matters will not be repeated.

[0101] Figure 8 is a perspective view showing the hair beauty device of the second embodiment. Figure 9 is Figure 8 the top view of the lower body shown. Figure 10 is Figure 8 the bottom view of the upper body shown.

[0102] In addition, in the following description, Figure 8 the left side in Figure 9 is also described as the "front end side", and the right side is also described as the "base end side", Figure 10 and Figure 9 the lower side in Figure 10 is also described as the "front end side", and the upper side is also described as the "base end side". And,

[0103] The hair beauty device 1 of the second embodiment is mainly different in the front end side structure of the lower body 2 and the upper body 3, and the others are the same as the hair beauty device 1 of the first embodiment.

[0104] As Figure 8 and Figure 9As shown, the hairbrush part 5 is omitted from the lower main body 2, and the vibrating plate 211 has a shape that spans the entire short side direction of the lower cover 222 and the two upper end parts of the lower case 221. With this configuration, when hair passes through the gap between the lower main body 2 and the upper main body 3 in a state where they are close to each other, the contact time between the vibrating plate 211 and the hair can be extended. Therefore, the efficiency of the liquid agent penetrating into the hair can be further improved.

[0105] Moreover, as Figure 8 and Figure 10 shown, the light emitting part 310 is exposed on both sides of the upper main body 3. With this configuration, it is easy to visually recognize that the penetration treatment is in progress. Also, since the size of the heating plate 311 can be increased, when hair passes through the gap between the lower main body 2 and the upper main body 3 in a state where they are close to each other, the contact time between the heating plate 311 and the hair can be extended. From this perspective, the efficiency of the liquid agent penetrating into the hair can also be further improved.

[0106] Moreover, in the second embodiment, the interface part 39 is provided at the base end part of the lower main body 2, instead of being provided at the base end part of the upper main body 3.

[0107] According to the hair beauty device 1 and the penetration treatment method as described above, the liquid agent can be smoothly and sufficiently penetrated into the hair.

[0108] Here, as the liquid agent that can be used for hair, for example, a hair treatment agent, a hair dye, etc. can be cited, and one or a combination of two or more thereof can be used.

[0109] It can also be provided by the following various forms.

[0160] 2. Measurement and evaluation

[0161] 2-1. Measurement of penetration area ratio (penetration efficiency)

[0162] The penetration area ratio (penetration efficiency) was measured as follows for the hair bundle that was left to stand for one day or more after drying.

[0163] First, gather your hair strands in 2cm widths on two overlapping sheets of white copy paper.

[0164] Next, L* was measured using a spectrocolorimeter (model CM-26d) at five locations spaced about 1 cm apart along the longitudinal direction of each hair bundle, for a total of 10 locations on the front and back sides.

[0165] And find the average value of the measured L*.

[0166] Then, the hair bundle having L* closest to the average value is selected as the test object.

[0167] Then, the selected hair bundle was immersed in a cryoembedding medium and placed in a -100°C cold trap (model UT-2000) for 5 minutes to prepare a block.

[0168] The blocks were then cut into 14 μm thick sections using a cryostat (model CM3050S) and transferred to glass slides. Cryofilm was used to prevent sections from curling.

[0169] Next, slice images were taken using a digital microscope (model VHX-6000) at a magnification of 1000 times.

[0170] Then, the cross-sectional area of each hair was calculated based on the obtained images, and the cross-sectional area of each hair was calculated from the image obtained. 2 Above and 9000μm 2 From the following hairs, 12 or more and 14 or fewer hairs were randomly sampled to confirm that there was no significant difference in cross-sectional area between the groups.

[0171] Then, excluding the high and low penetration area ratios (red area ÷ hair cross-sectional area), 10 hairs in the middle were selected and the average value was calculated.

[0172] 2-2. Evaluation of bleached hair surface condition

[0173] The bleached hair was magnified and observed with an optical microscope, and the surface condition was evaluated according to the following criteria.

[0174] ◎: The surface of the bleached hair has no damage.

[0175] ○: There are some damages on the surface of the bleached hair.

[0176] △: There are relatively large damages on the surface of the bleached hair.

[0177] ×: There are very large damages on the surface of the bleached hair.

[0178] 3. Results

[0179] The results are shown in Table 1 below.

[0180] [Table 1]

[0181]

[0182] 4. Impregnation treatment B (Example B1)

[0183] First, real human white hair (model BM-W-A) with a length of 10 cm and a mass of about 1 g per strand was prepared in the form of hair strands.

[0184] Next, after soaking the hair strands in normal temperature water for more than 1 hour, about 0.2 g of shampoo was spread and held with both hands, and rubbed back and forth 10 times on each of the upper and lower sides.

[0185] Then, warm water was continuously poured into the bucket, taking care to avoid the flowing water directly hitting the hair strands, and an operation of stirring in an eight-character shape was performed at a speed of once per second for 1 minute.

[0186] Then, the hair strands taken out of the bucket were combed with a comb, and the moisture was removed with kitchen paper until it reached about 1.4 g ± 0.1 g.

[0187] Next, about 2 g of cosmetics (a liquid containing HC Yellow 4, HC Blue 2, Basic Blue 75, and Basic Brown 16) was evenly spread on both the front and back sides of the hair strands with the index finger.

[0188] Then, between the lower main body 2 and the upper main body 3 of the hair beauty device 1 with the power turned on, the hair strands were clamped in the length direction, and the lower main body 2 and the upper main body 3 were opened and closed once every 10 seconds. After placing the hair strands on the hair beauty device 1 for 5 minutes (half of the impregnation treatment time), the hair strands were turned over on both the front and back sides.

[0189] In addition, the heating temperature was set at 60 °C, and the vibration output value was set at 0.074 W per unit area [cm 2 of the vibration plate.

[0190] Then, 1 minute after 10 minutes (the impregnation treatment time) ended, the cosmetics were rinsed off the hair strands in the same way as above.

[0191] Next, wrap the hair bundle with kitchen paper (without applying pressure) and gently remove the moisture. Then, with the hair bundle suspended in the air, use a hair dryer (model: VEDA Bright BS for Salon TURBO) to blow hot air at a distance of 10 cm from the air outlet for 4 minutes, while grasping it by hand to dry it.

[0192] (Example B2)

[0193] Except that the heating temperature is changed to 80 °C and the vibration output value is changed to 0.128 W per unit area [cm 2 of the vibrating plate, the impregnation treatment is carried out in the same manner as in Example B1.

[0194] 5. Measurement of the blackness of the hair bundle surface

[0195] Measure the surface blackness of the hair bundle that has been left standing for more than 1 day after drying as follows.

[0196] First, place the hair bundle on two overlapping white copy papers, gathered in a width of 2 cm.

[0197] Next, at 5 positions along the length direction of each hair bundle, separated by an interval of about 1 cm, measure L* at a total of 10 positions on both the front and back sides using a spectrocolorimeter (model: CM-26d).

[0198] And calculate the average value of the measured L*.

[0199] As a result, L* is 32.8 in Example B1 and 31.1 in Example B2. The smaller this value indicates the higher the blackness. From this result, it can be understood that by increasing the vibration output value, the efficiency of the liquid agent penetrating into the hair is improved.
