  • FIG. 1 A cross-sectional view for schematically illustrating a hair-root portion in curly hair is shown in FIG. 1 .
  • a hair root 3 is a portion, which is positioned in a hair follicle 2 , a part of which is completed by being constituted of a scalp 4 .
  • this hair root 3 is curbed as an arc shape.
  • the permanent treatment liquid permeates into the hair root 3 within the hair follicle 2 .
  • the permanent treatment liquid permeates into the hair root 3 , since thioglycolic acid, which is included in the permanent treatment liquid, acts to the hair root 3 , the elasticity of the hair root 3 becomes small, and additionally flexibility is given to the hair root 3 .
  • a hair base end 5 is a part, which contacts with a hair papilla 6 , the bottom of the hair follicle 2 , the elongation of the hair 1 occurs because of the fact that the cell division occurs here. Therefore, since the hair base end 5 receives a certain action because of the fact that the hair root 3 is shaped to a straight configuration, it is believed that the hair 1 , which extends after the permanent treatment, turns into a straight-hair shape.
  • the permanent treatment liquid is adhered onto the portions alone, which are separated from the hair root, among the hair. It is because of the fact that, in the permanent treatment method for shaping hair to straight hair, since external forces, such as pulling and compressing, are applied to the hair, there is a fear that the hair might be cut off upon pulling if the permanent treatment liquid is adhered onto a portion, which is close to the hair root among the hair, to make the elasticity of this portion small.
  • the permanent treatment liquid does not permeate down to the hair root, and accordingly hair, which has extended anew since the permanent treatment, has been still kept to be as curly hair.
  • the permanent treatment method of the present invention because of the fact that the permanent treatment liquid is permeated down to the hair root and the hair is pulled while warming it, it is possible to turn the hair, which extends after the permanent treatment, into a straight-hair shape, as described above.
  • the treatment powder used in the treatment-liquid absorbing step can be at least one member of hydrophillic organic powders and hydrophillic inorganic powders.
  • Thioglycolic acid (C 2 H 4 O 2 S) which is included in the permanent treatment liquid, is a water-soluble liquid, which is referred to as mercaptoacetic acid or mercaptoethanoic acid, and the permanent treatment liquid is an aqueous solution in which thioglycolic acid is dissolved into water. Consequently, by means of the hydrophillic treatment powder, the permanent treatment liquid is adsorbed or absorbed very well.
  • the permanent treatment liquid becomes likely to permeate into the hair root, and accordingly it is possible to turn hair, which extends after the permanent treatment, into a straight-hair state more securely.
  • the “warming temperature” set forth herein is referred to as the temperature of means per se for warming the hair.
  • the instance of adapting a portion, among the hair iron, which is brought into contact with the hair to be 100° C. or more is referred to as “adapting the warming temperature of the hair to be 100° C. or more.” Since the higher the warming temperature is the more the shaping action enlarges, it is desired to adapt it to be 220° C. approximately.
  • the treatment liquid which is adhered on the hair, causes a kind of water-vapor explosion so that it has been dangerous.
  • the warming temperature exceeds 200° C.
  • the treatment powder absorbs the permanent treatment liquid to turn it into a dry state so that no water vapor blows up.
  • the shaping step dividedly twice; to carry out a pre-shaping step, the first shaping step, between the permeating step and the treatment-liquid absorbing step; and to carry out a post-shaping step, the second shaping step, after the treatment-liquid absorbing step. Because of the fact that a portion, among the hair, which has not been shaped completely by mean of the pre-shaping step is detected; and the portion is shaped once again by means of the post-shaping step, the hair is shaped to straight hair more securely. And, hair, which extends after the permanent treatment, too, turns into straight hair more securely.

  • FIG. 9 is the A-A cross-sectional diagram of FIG. 8 .
  • the permanent treatment liquid is such that it is possible to employ known ones which include thioglycolic acid.
  • the concentration of thioglycolic acid included in the permanent treatment liquid can preferably be 7% by weight or less with respect to the permanent treatment liquid. As described above, it is because of suppressing cut-off hair upon shaping. Note that, in the case where the concentration of thioglycolic acid in the permanent treatment liquid exceeds 7% by weight, cut-off hair becomes likely to occur during shaping, however, in this case as well, hair, which has extended since the permanent treatment, turns into straight hair. Therefore, the concentration of thioglycolic acid in the permanent treatment liquid can exceed 7% by weight.
  • the concentration of thioglycolic acid in the permanent treatment liquid can desirably be 4.5% by weight or more and 7% by weight or less. It is adapted to be 4.5% by weight or more, because the higher the concentration of thioglycolic acid is the more securely the shaping can be done in a shorter period of time. Note that, even when the concentration of thioglycolic acid is less than 4.5% by weight, it is possible to shape the hair to a straight-hair shape securely by increasing the amount of the permanent treatment liquid to be adhered onto the hair or prolonging the time taken for the permeating step and shaping step. And, in this case as well, hair, which has extended since the permanent treatment step, turns into straight hair.
  • cysteine similarly to thioglycolic acid, produces hydrogen ions and works as a reducing agent for reducing cystine. Since the reducing action of cystine by means of cysteine is weaker than thioglycolic acid, by using cysteine with thioglycolic acid combinedly, such an effect is available that the hair becomes less likely to be cut off upon shaping. In this case, the sum of the concentration of thioglycolic acid and the concentration of cysteine can preferably be 7% by weight of the entirety of the permanent treatment liquid.
  • the pH of the permanent treatment liquid can preferably fall in the range of 4.5-9.6, and can desirably be 8-9 approximately.
  • thioglycolic acid is acidic, it is possible to set up the pH of the permanent treatment liquid in the aforementioned range by compounding a known alkaline agent, which is represented by ammonia or monoethanolamine, with the permanent treatment liquid.
  • a known alkaline agent which is represented by ammonia or monoethanolamine
  • the part of the hair onto which the permanent treatment liquid is adhered is such that the more adjacent position to the hair root is the more preferable it is.
  • the permanent treatment liquid goes into the hair follicle directly or transmits through the scalp or hair shaft to permeate into the hair root.
  • the permanent treatment liquid moves in the hair-root direction by means of the capillary phenomenon between hairs neighboring with each other, even in the case of adhering the permanent treatment liquid onto the hair root, a portion coming out from the hair follicle, alone, the permanent liquid goes into the inside of the hair follicle to permeate into the hair root.
  • the permanent treatment liquid which has adhered on the hair-shaft surface, permeates into the inside of the hair and reaches the hair root.
  • the permanent treatment liquid is such that it is preferable to adhere it onto such an extent of position that, among the hair shaft, a portion around the hair follicle is wetted by means of the permanent treatment liquid.
  • the permeating step is such that it is preferable to carry it out while warming the hair, however, the temperature at this moment can preferably be 30-45° C. Since the reaction rate that cystine is reduced by means of thioglycol depends on the temperature, in the case where a large temperature unevenness exists depending on the parts of the hair, there might arise cases where the hair cannot be shaped homogeneously. However, in the case of carrying out the permeating step while warming the hair, since the temperature unevenness is reduced so that the cystine of the hair is reduced without unevenness, it is possible to shape the hair homogeneously in the shaping step. Moreover, in this permeating step, by covering the hair with a cap or wrapping material, and the like, it is possible as well to reduce the temperature unevenness much more.
  • this permeating step is such that it is preferable to leave the hair for a while after the permanent treatment liquid is adhered onto it, and it is desirable to leave it for 20 minutes or more. It is because of reducing cystine in the hair more securely by permeating it thereinto while taking time.
  • the permeating step and/or the shaping step can preferably be carried out while vibrating it with ultrasonic vibrating means, however, the frequency of ultrasonic wave in this instance can preferably fall in the range of 20-100 kHz.
  • the power of ultrasonic wave is higher, the treatment liquid permeates into the hair root even in a shorter vibrating time; and when it is lower, it is advisable to lengthen the vibrating time.
  • ultrasonic vibrating means whose frequency is 20 kHz and power is 10-20 W.

  • the temperature for warming the hair which is in such a state that the permanent treatment liquid is adhered thereon without the treatment-liquid absorbing step, can desirably fall in the range of 160-180° C.
  • a temperature which acts onto the hair actually, becomes a temperature of being the warming temperature or less, and accordingly it does not cause so-called water-vapor explosion.
  • the hair-warming temperature falls in this range, it is possible to shape the hair to a sufficient straight-hair shape in a short time relatively.
  • the shaping step in the case of warming it after the treatment-liquid absorbing step, it can preferably fall in the range of 200-250° C.
  • the treatment liquid is absorbed into the treatment powder so that the hair is turned into a dry state, it does not result in water-vapor explosion.
  • the hair-warming temperature falls in this range, it is possible to shape the hair to a sufficient straight-hair shape in a short time relatively.
  • the force for pulling the hair can be smaller relatively, for instance.
  • the force for pulling the hair can be 0.5 kg/cm 2 or more, and can more preferably be 0.8 kg/cm 2 or more. And, it can desirably be 1.0 kg/cm 2 or more.
  • the force for pulling the hair set forth herein is judged by the extent that the scalp is pulled. For example, the case where the scalp is pulled to the same extent as that a 10-kg weight is hung from hairs, which are grown in 10 square cm, to pull them down is referred to as “the hair is pulled with 1 kg/cm 2 .”
