[0002]

2. Description of the Related Art A permanent wave treatment for imparting a wave with a permanent wave composition is carried out by applying a first permanent wave agent containing a reducing agent composed of thioglycolic acid or a salt thereof, cysteine or a salt thereof to hair. The hair is wound around a rod or the like (the hair may be wound around the rod and then the first agent may be applied to the hair), and in that state, the disulfide bond of cystine in keratin, which is a constituent protein (protein) of hair, is added as described above. Reductively cleaves with a reducing agent to form a mercapto compound, and then oxidizes the mercapto group with a second agent for a permanent wave, which is mainly composed of an oxidizing agent such as sodium bromate and hydrogen peroxide, and disulfide bond at a new position. By reforming and fixing the wave.

[0003]

However, in the treatment with the above composition for permanent wave, the second
When the wave shape at the time of removing the rod and washing with water after treatment with the agent is compared with the wave shape at the time of drying the hair, the wave existing immediately after the treatment is said to be stretched and lost after drying. There were many problems, and there was a problem that it could not be solved even if the processing time or the usage amount was changed.

Therefore, the present invention solves the problems in the prior art as described above, and the wave does not extend and disappear even after the permanent wave treatment is finished and dried, and the wave shape immediately after the second agent treatment is finished. An object of the present invention is to provide a composition for a permanent wave and a method for treating a permanent wave, which can make the wave shape after drying have a similar shape in a natural state.

[0005]

As a result of intensive studies to solve the above problems, the present inventors have found that N- [2-hydroxy-3- (trimethylammonio) chloride N- [2-hydroxy-3- (trimethylammonio)) was used as the first agent for permanent waves. Propyl] hydrolyzed silk is contained, and the second agent for permanent wave is made to contain polyoxyethylene oleyl ether, and when the permanent wave treatment of hair is performed using them, the wave shape immediately after the above second agent treatment is completed. We found that the wave shape after drying can be made similar in a natural state,
The present invention has been completed.

That is, the first gist of the present invention is N chloride.

The second gist of the present invention is to use the above-mentioned N- [2-hydroxy-3- (trimethylammonio) chloride chloride for hair.
Propyl] hydrolyzed silk-containing permanent wave first agent, and then the above polyoxyethylene oleyl ether-containing permanent wave second agent
It exists in a permanent wave treatment method characterized by treating with a chemical.

In the present invention, the content of the N- [2-hydroxy-3- (trimethylammonio) propyl] hydrolyzed chloride chloride in the first agent for permanent wave is 0.01 to 1% by mass. It is a preferable embodiment that the content of the polyoxyethylene oleyl ether in the second agent for permanent wave is 0.01 to 2% by mass.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION The permanent wave composition of the present invention comprises a first agent, N- [2-hydroxy-3-chloride].
(Trimethylammonio) propyl] hydrolyzed silk is contained, and the second agent is characterized by containing polyoxyethylene oleyl ether, but other than that, the conventional constitution can be adopted. For example, the first agent for permanent wave of the present invention contains a reducing agent as in the case of the conventional first agent for permanent wave, and examples of such a reducing agent include thioglycolic acid or ammonium thioglycolate. Thioglycolate,
Cysteine, cysteine salts such as cysteine hydrochloride,
At least one of cysteine derivatives such as N-acetyl cysteine, monoglyceryl thioglycolate, cysteamine, thiolactic acid, sulfite, and hydrogen sulfite is used.

The reducing agents can be used alone or in combination of two or more kinds, and the content of the reducing agent in the first agent (the blending amount in the first agent) is 1 to 20% by mass, particularly 2 to 11% by mass is preferred.

The N- [2-hydroxy-3- (trimethylammonio) propyl] hydrolyzed chloride chloride contained in the first agent for the permanent wave of the present invention has the action of imparting softness to hair and the second agent. Due to the synergistic action with the polyoxyethylene oleyl ether contained in the hair, even if the permanent wave treatment is finished and dried, the wave does not extend and disappear, and
It plays a role of making the wave shape immediately after the treatment with the agent and the wave shape after drying become similar in a natural state.

The N- [2-hydroxy-3- (trimethylammonio) propyl] hydrolyzed chloride chloride preferably has an average molecular weight of 550 to 1200. A specific example of the N- [2-hydroxy-3- (trimethylammonio) propyl] hydrolyzed silk chloride under the trade name is, for example, from Seiwa Kasei Co., Ltd., Promois Silk-
Examples include products marketed under product names such as 1000Q and Promois Silk-700Q.

The above N- [2-hydroxy-chloride]
The content of 3- (trimethylammonio) propyl] hydrolyzed silk in the first agent for the permanent wave (the amount blended in the first agent) is 0.01 to 1% by mass, and particularly 0.1.
2 to 0.5 mass% is preferable. That is, N- [2 chloride
-Hydroxy-3- (trimethylammonio) propyl] hydrolyzed silk in the content of the first agent for permanent wave less than the above range, the above-mentioned action cannot be sufficiently exhibited, and When the amount is larger than the range, the amount of adsorption to hair becomes too large, and therefore, the reducing action of the reducing agent may be hindered and the wave forming power may be weakened.

In addition to the above reducing agent, N- [2-hydroxy-3- (trimethylammonio) propyl] hydrolyzed chloride, the first agent for permanent wave of the present invention includes conventional first permanent wave agents. The same substances as those incorporated in the agent can be appropriately incorporated as necessary. Examples of such components include ammonium hydrogen carbonate, aqueous ammonia, triethanolamine,
Alkaline agents such as monoethanolamine, anionic surfactants, cationic surfactants, amphoteric surfactants, various surfactants such as nonionic surfactants, wetting of propylene glycol, 1,3-butylene glycol, glycerin, etc. Agents, paraffins, fatty acid esters, oils and fats such as animal and vegetable oils, higher alcohols such as cetyl alcohol, stearyl alcohol and oleyl alcohol, and hydrolysates of animal and plant derived proteins such as collagen, keratin, silk, soybean protein and wheat protein. Examples include derivatives, hair protectants, preservatives, stabilizers, anti-inflammatory agents, coloring agents, chelating agents, and fragrances.

As described above, in the composition for permanent wave of the present invention, the first agent contains N- [2-hydroxy-3- (trimethylammonio) propyl] hydrolyzed silk liquid, and the second agent is added. It is characterized in that it contains polyoxyethylene oleyl ether, but other than that, the conventional constitution can be adopted. For example, the second agent for permanent wave of the present invention is blended with an oxidizing agent like the conventional second agent for permanent wave. Examples of such an oxidizing agent include potassium bromate, sodium bromate, and peroxide. Examples thereof include sodium borate and hydrogen peroxide. The content of these oxidizing agents in the second agent (the amount of compounding in the second agent) is 1 to 20% by mass,
In particular, 2 to 10 mass% is preferable.

The polyoxyethylene oleyl ether contained in the second agent for the permanent wave of the present invention has a penetrating effect on hair, assists the penetration of the oxidizing agent, and at the same time, N- [Cl] chloride contained in the first agent. 2-hydroxy-
3- (Trimethylammonio) propyl] hydrolyzed silk has a synergistic effect to prevent the wave from extending even after the permanent wave treatment is finished and dried. It plays a role in making the shapes similar in a natural state.

As the above polyoxyethylene oleyl ether, one having an ethylene oxide addition mole number of 5 to 25 moles is suitable. Illustrating specific examples of this polyoxyethylene oleyl ether by the trade name, for example, BO-7, BO-10, BO-15, B from Nikko Chemicals Co., Ltd.
Examples include those marketed under the product names such as O-20.

As the polyoxyethylene oleyl ether, those belonging thereto can be used alone, or those having different addition mole numbers can be used in combination. The content of the above-mentioned polyoxyethylene oleyl ether in the second agent (blending amount in the second agent) is 0.01 to 2% by mass, and particularly 0.1 to 1.
5 mass% is preferable. That is, when the content of the polyoxyethylene oleyl ether in the second agent for permanent wave is less than the above range, the above effect cannot be sufficiently exhibited, and when it is more than the above range,
The amount adsorbed on the hair becomes too large, so that the oxidizing action of the oxidizing agent may be hindered and the wave forming power may be weakened.

In addition to the above-mentioned oxidizing agent and the above-mentioned polyoxyethylene oleyl ether, the second agent for permanent wave in the present invention is a second permanent wave agent.
The same thing as what was contained in the agent can be contained. Examples of such components include p of the preparation.
Examples thereof include phosphate, sodium hydroxide, etc. added for the purpose of H buffering, and surfactants, touch improvers, chelating agents, fragrances, preservatives, etc. added as hair permeation promoters and hair protection agents.

Both the first agent and the second agent of the permanent wave composition of the present invention can be prepared by dissolving or dispersing the above components in water or an aqueous liquid containing water as a main ingredient, and the preparation method itself is It is no different from the case of preparing the usual first and second agents for permanent wave.
Further, the composition for permanent wave of the present invention can be prepared as a so-called cold type permanent wave composition for imparting waves to hair at room temperature, and also imparts waves to hair under heating. In order to do so, it is also possible to prepare a so-called warming type permanent wave composition. Further, it can be prepared as a composition for a permanent wave for so-called cold type straight perm treatment, which straightens and straightens curly hair at room temperature, or straightens and straightens curly hair under heating. Also, it can be prepared as a composition for permanent wave for so-called heating type straight perm treatment.

2 and the compositions for permanent wave of Comparative Examples 1 to 4.

[0031]

[Table 5]

While making the combinations of the above-mentioned first agent and second agent as shown in Table 5, the hair bundle was subjected to a permanent wave treatment as shown below.

Healthy hair collected from the same person with a length of 210 m
A hair bundle with a weight of 0.5 g was prepared, and the hair bundle was washed with a 10% sodium lauryl sulfate aqueous solution and dried, and then 0.3 ml each of the first agent was applied to the hair bundle and the mixture was allowed to stand at room temperature. Hold for 20 minutes, during which the above bundle of hair is wrapped around a rod with a diameter of 17 mm (about 4 turns), then the first
0.7 ml of each agent was applied, left at 45 ° C for 15 minutes, washed with water, then 0.7 ml of the second agent was applied, left at room temperature for 10 minutes, and then 0.3 ml of the second agent was applied. Then, it was left for 5 minutes, washed with water, and naturally dried for 24 hours to complete the permanent wave treatment.

After the treatment of the second agent for the permanent wave, the rod was removed from the hair bundle, washed with water, and the wave shape of the hair bundle at the time when the water was wiped off was examined, and the wave shape at the time when the hair bundle was dried was examined. The shape was examined. The second
The hair bundle after the agent treatment means a hair bundle that has been washed with water after the second agent treatment and wiped off water, and the hair bundle after drying means that after washing with water,
A hair bundle that has been naturally dried for 24 hours.

In examining the wave shape, first, the hair bundle after the second agent treatment and the hair bundle after drying are suspended in a spiral shape (spiral shape) in the same direction. The hair bundle in this state is shown in FIGS. 1 shows the hair bundle after the second agent treatment with the composition for permanent wave of Example 1 and the hair bundle after drying, and FIG. 2 shows the hair after the second agent treatment with the composition for permanent wave of Example 2. Fig. 3 shows a bundle and a hair bundle after drying, Fig. 3 shows a bundle of hair after the second agent treatment with the composition for a permanent wave of Comparative Example 1 and a bundle of hair after drying, and Fig. 4 is for a permanent wave of Comparative Example 2. FIG. 5 shows the hair bundles after the second agent treatment with the composition and the hair bundles after drying, and FIG. 5 shows the hair bundles after the second agent treatment with the composition for a permanent wave of Comparative Example 3 and the hair bundles after drying, FIG. 6 shows a hair bundle after the second agent treatment and a hair bundle after drying with the composition for a permanent wave of Comparative Example 4.

Next, the specification of the peaks used for calculating the difference between the wave shape after the second agent treatment and the wave shape after drying will be described. The position of the tip (free end side) of the above-mentioned hair bundle is described. When fixed (but not loaded, fixed in the natural state) and observed from the side, the peak of the sine curve is the peak, the tip of the hair is the starting point, and the first peak in order from that tip, The second mountain, the third mountain ... are defined. The mountain portion is indicated by an arrow “→” and an arrow “←” in FIGS.

Then, the length from the root to each mountain is measured for one rotation from the hair tip to the second mountain, and the length from the root to the wave mountain after the second agent treatment is measured for each corresponding mountain. The length (referred to as "A") and the length of the hair bundle after drying (referred to as "B") were measured. The results are shown in Table 6 and Table 7, respectively. The length (B) to the peak after the second agent treatment is subtracted from the length (A) to the peak after the second agent treatment (that is, "B-A" is obtained), and the resultant is the wave after the second agent treatment. The difference between the shape and the wave shape after drying is shown, and the result is simplified in Table 8 and expressed as “difference in wave shape”. In addition, Table 8 shows that
The sum of the differences in the wave shapes of the peak, the first peak, and the tip of the hair is indicated by the item "total".

Incidentally, in determining the difference between the wave shape after the second agent treatment and the wave shape after drying, what is done from the tip of the hair to the second crest is, in practice, after the second agent treatment of that portion. This is because the difference between the wavy shape and the wavy shape after drying becomes a problem.
If the wave shape after agent treatment and the wave shape after drying are similar shapes, even if there is a slight difference between the wave shape after the second agent treatment and the wave shape after drying at the rod side part, This is because that part is hidden and does not pose a problem in the permanent wave treatment of actual hair.

[0039]

[Table 6]

[0040]

[Table 7]

[0041]

[Table 8]

As is clear from the results shown in Table 8 (in particular, the "total" item), Examples 1 and 2 are different from Comparative Examples 1 to 4 in the wave shape after the second agent treatment and the wave shape after drying. There is little difference from the shape.

Next, the similar shape of the wave was examined. First, how the position of the crest changed after the second agent treatment and after the drying was calculated by the following calculation formula.

[0044]

[0045]

Table 9 shows the position and the change (after treatment / drying) of the second mountain, and Table 10 shows the position and the change (after treatment / drying) of the first mountain. In addition,
In Table 9 and Table 10, “after treatment / after treatment after drying” means after the second agent treatment.

[0047]

[Table 9]

[0048]

[Table 10]

Next, as shown in Table 9 above, the values after the second agent treatment / drying obtained with respect to the change in the position of the second peak and the position of the first peak as shown in Table 10 above. Table 11 shows the sum of the changes and the values after the second agent treatment / after the drying.

[0050]

[Table 11]

As is clear from the results shown in Table 11, in Examples 1 and 2, compared with Comparative Examples 1 to 4, the change in the position of the crest was small and the similar shapes were maintained.

Next, a beauty technician 6 who is specialized in softness using the hair bundle after the permanent wave treatment.
Sensory evaluation was performed by name. The results are shown in Table 12.
However, in displaying the evaluation results in Table 12, the evaluation results are symbolized according to the following criteria.

⊚: 5 to 6 out of 6 beauty technicians evaluated that the softness was excellent. Good: 3 to 4 out of 6 beauty technicians evaluated that the softness was excellent. Δ: Two out of six beauty technicians evaluated that the softness was excellent. X: Out of 6 beauty engineers, 1 or less evaluated that the softness was excellent.

[0054]

[Table 12]

As shown in Table 12, the hair treated with the permanent wave compositions of Examples 1 and 2 for permanent wave was excellent in softness. This is the composition for permanent wave of Examples 1-2 of the present invention,
This is because the first agent contained N- [2-hydroxy-3- (trimethylammonio) propyl] hydrolyzed silk chloride. The composition for the permanent wave of Comparative Example 4 was also excellent in softness because it contained N- [2-hydroxy-3- (trimethylammonio) propyl] hydrolyzed chloride chloride in the first agent. However, as described above, in the permanent wave composition of Comparative Example 4, there is a large change in the positions of the peaks after the treatment with the second agent and after the drying, and in the case of the permanent wave compositions of Examples 1 and 2, I couldn't keep a similar shape like.

Examples 3 to 4 and Comparative Examples 5 to 8 Four kinds of the first agents for permanent wave having the compositions shown in Tables 13 and 14 were prepared, and the second agent was the product of the present invention prepared as described above. 2-1, Invention Product 2-2, and Comparative Product 2-1
And the first agent and the second agent were combined as shown in Table 15 to obtain compositions for permanent waves of Examples 3 to 4 and Comparative Examples 5 to 8. The numerical values showing the blending amount of each component shown in the table are parts by mass. For components that are not pure components, the concentration is shown in parentheses at the end of the component name. The term "residual" in the table means the amount by which the total amount becomes 100 parts by mass.

In the preparation of the first composition for the permanent wave, ammonium thioglycolate is used as the reducing agent, and N- [2-hydroxy-3-chloride] is used.
As (trimethylammonio) propyl] hydrolyzed silk, as in Example 1 and the like, one having a concentration of 7%, which is commercially available from Seiwa Kasei Co. under the trade name of Promois Silk 1000-Q, is used. 2-hydroxy-3-
(Trimethylammonio) propyl] Hydrolyzed silk was included in the product of the present invention 1-2, and N-chloride was used.
[2-Hydroxy-3- (trimethylammonio) propyl] A product containing no hydrolyzed silk was designated as "Comparative product 1-4", and N- [2-hydroxy-3- (trimethylammonio) propyl] chloride was used. Instead of hydrolyzed silk, N- [2-hydroxy-3- (trimethylammonio) propyl] hydrolyzed keratin was contained as "Comparative Product 1-5", and N- [2-hydroxy-chloride] was used.
The product containing 3- (trimethylammonio) propyl] hydrolyzed collagen was designated as “Comparative Product 1-6”.

Then, as described above, in the preparation of the second agent for the permanent wave, sodium bromate was used as the oxidizing agent, and polyoxyethylene oleyl ether was contained as "inventive product 2-1". The product containing no polyoxyethylene oleyl ether is referred to as "comparative product 2-1".

[0059]

[Table 13]

[0060]

[Table 14]

The first agent and the second agent prepared as described above were combined as shown in Table 15 below to obtain the permanent wave compositions of Examples 3 to 4 and Comparative Examples 5 to 8.

[0062]

[Table 15]

While the combinations of the above-mentioned first agent and second agent were made as shown in Table 15 above, the hair bundle was subjected to a permanent wave treatment as shown below.

Healthy hair collected from the same person with a length of 210 m
A hair bundle with a weight of 0.5 g was prepared, and the hair bundle was washed with a 10% aqueous solution of sodium lauryl sulfate and dried, and then 0.3 ml each of the first agent was applied to the hair bundle, and the hair bundle was heated at room temperature. Hold for 20 minutes, during which the above bundle of hair is wrapped around a rod with a diameter of 17 mm (about 4 turns), then the first
Apply 0.7 ml of each agent, and in the constant temperature atmosphere of 25 ℃,
After leaving it for 1 minute, wash it with water, then apply 0.7 ml of the second agent, leave it for 10 minutes at room temperature, then apply 0.3 ml of the second agent, leave it for 5 minutes, then wash it with water for 24 hours. After permanent drying, the permanent wave treatment was completed.

After the treatment of the second agent for permanent wave, the rod was removed from the hair bundle, washed with water, and the wave shape of the hair bundle at the time when the water was wiped off was examined, and the wave shape at the time of drying the hair bundle was examined. The shape was examined. The second
The hair bundle after the agent treatment means a hair bundle that has been washed with water after the second agent treatment and wiped off water, and the hair bundle after drying means that after washing with water,
A hair bundle that has been naturally dried for 24 hours.

In examining the wave shape, first, as in Example 1 and the like, first, the hair bundle after the second agent treatment and the hair bundle after drying are suspended in a spiral shape (spiral shape) in the same direction. Lower. The hair bundle in this state is shown in FIGS. FIG. 7 shows the hair bundle after the second agent treatment and the hair bundle after drying with the composition for permanent wave of Example 3.
FIG. 8 shows a hair bundle after the second agent treatment and a hair bundle after drying with the permanent wave composition of Example 4, and FIG. 9 shows hair after the second agent treatment with the permanent wave composition of Comparative Example 5. Fig. 10 shows a bundle and a bundle of hair after drying, Fig. 10 shows a bundle of hair after the second agent treatment with the composition for a permanent wave of Comparative Example 6 and a bundle of hair after drying, and Fig. 11 shows Comparative Example 7
FIG. 12 shows a hair bundle after the second agent treatment and a hair bundle after drying with the permanent wave composition of FIG. 12, and FIG. 12 shows a hair bundle after the second agent treatment with the permanent wave composition of Comparative Example 8 and a hair after drying. Show a bunch.

Next, as in the case of the first embodiment, the peaks used in calculating the difference between the wave shape after the second agent treatment and the wave shape after drying are specified. That is, fix the position of the tip (free end side) of the above-mentioned hair bundle (however, fix it in a natural state without applying a load)
When observed from the side, the peak of the sine curve is taken as the peak, and the tip of the hair is taken as the starting point.
The second mountain, the third mountain ... are defined. Figure 7-
In FIG. 12, an arrow “→” and an arrow “←” are shown.

Then, the length from the root to each crest is measured for one rotation from the tip of the hair to the second crest, and the length of the corresponding crest to the crest of the hair bundle after the second agent treatment is measured. (This is referred to as "A") and the length of the pile of hair after drying (this is referred to as "B") was measured. The results are shown in Tables 16 and 17, respectively. The length (A) from the dried pile (B) to the pile after the second agent treatment is subtracted (that is, "(B)-(A)" is obtained), and the second formulation is used. The difference between the wave shape after the treatment and the wave shape after drying was taken, and the result is simplified in Table 18 and expressed as "difference in wave shape". Further, in Table 18, the sum of the differences in the wave shapes of the second crest, the first crest and the bristle tip is shown by the item "total".

In determining the difference between the wavy shape after the treatment with the second agent and the wavy shape after drying, what is done from the tip of the hair to the second crest is the same as in Example 1 above. , Because the difference between the wave shape after the second agent treatment and the wave shape after drying at that portion becomes a problem,
If the wave shape after the second agent treatment from the tip of the hair to the second crest is similar to the wave shape after the drying, the wave shape after the second agent treatment and the wave after the drying at the rod side part This is because even if there is a slight difference in shape, that portion is hidden by the permanent wave treatment of the actual hair and it does not pose a problem.

[0070]

[Table 16]

[0071]

[Table 17]

[0072]

[Table 18]

As is clear from the results shown in Table 18 (particularly, "total" item), Examples 3 to 4 are different from Comparative Examples 5 to 8 in the wave shape after the second agent treatment and the wave after drying. There is little difference from the shape.

Next, the similar shape of the wave was examined. First, as in the case of Example 1 and the like, how the position of the crest changed after the second agent treatment and after the drying was calculated by the following calculation formula.

[0075]

[0076]

Table 19 shows the positions and changes (after treatment / drying) of the second mountain, and Table 20 shows positions and changes thereof (after treatment / drying) of the first mountain. In Tables 19 and 20, “after treatment / after treatment after drying” means after the second agent treatment.

[0078]

[0079]

[Table 20]

Next, as shown in Table 19 above, the values after the second agent treatment / drying obtained with respect to the change in the position of the second peak and the positions of the first peak as shown in Table 20 above are shown. Table 21 shows the sum of the changes and the values after the second agent treatment / after the drying.

[0081]

[Table 21]

As is clear from the results shown in Table 21, in Examples 3 to 4, the change in the position of the crest was small and the similar shapes were maintained, as compared with Comparative Examples 5 to 8.

Then, using the hair bundle after the above permanent wave treatment, the softness was subjected to a sensory evaluation by 6 professional beauty engineers in the same manner as in Example 1 and the like. The results are shown in Table 22. However, in displaying the evaluation results in Table 22, the evaluation results are symbolized according to the same criteria as those in Example 1 and the like.

[0084]

[Table 22]

As shown in Table 22, the hairs treated with the permanent wave compositions of Examples 3 to 4 were treated in the same manner as the hairs treated with the permanent wave compositions of Examples 1 and 2 described above. The softness was excellent. This is because in the compositions for permanent waves of Examples 3 to 4, N- [2-hydroxy-3- (trimethylammonio) chloride N- [2-hydroxy-3-] was used as the first agent.
Propyl] hydrolyzed silk is considered to be the result.

Examples 1 and 2 exemplify cysteine-based and heating-type compositions for permanent wave, and Examples 3 and 4 illustrate thioglycolic acid-based and cold-type compositions for permanent wave. However, in the case of a cysteine-based composition for cold permanent wave and also in a thioglycolic acid-based composition for heating permanent wave, the wave shape after the second agent treatment was performed in the same manner as in the above-mentioned Examples. The difference between the wavy shape after drying and the wavy shape after drying is small, the similar shape is maintained, and the softening effect is provided.

[0087]

As described above, according to the present invention, the wave shape after the second agent treatment and the wave shape after drying are natural without the wave extending and disappearing even after the permanent wave treatment is finished and dried. It was possible to provide a composition for a permanent wave and a method for treating a permanent wave, which can be made to have a similar shape in a state.
