Technical Field

The present invention relates to a hair treatment method.

Background

Curling manually imparted to hair by a technique such as permanent wave treatment is partially reversed as time passes after the day, and this causes problems such as deterioration in aesthetic appearance and entanglement of hair with fingers. However, the prior art for the purpose of eliminating this problem does not exist.

Disclosure of Invention

In a first aspect of the present invention, there is provided a hair treatment method comprising the following steps [ a-1], [ B ] and [ C ] and carried out in the order of step [ a-1] → step [ B ] → step [ C ] or in the order of step [ B ] → step [ a-1] → step [ C ],

Detailed Description

The present invention relates to a hair treatment method for improving ease of curling by making the curling direction of natural curls or hair curls by a permanent wave treatment or the like uniform and tidy to restore the appearance and making the hair less likely to tangle.

As a result of extensive studies, the present inventors have found that not only curling artificially imparted by a technique such as permanent wave treatment, but also natural curling is likely to cause partial inversion of the curling direction into a disordered shape due to accumulation of calcium ions in water during daily shampooing, and thus the curling is likely to be tangled, and the appearance is impaired.

As a result of further intensive studies, the present inventors have found that by treating hair with a hydrophobic organic acid, a specific carboxylic acid and an aromatic sulfonic acid in a predetermined order, calcium ions accumulated in the hair are eluted, and the interior of the hair is modified with the carboxylic acid and the aromatic sulfonic acid, so that the treated hair has a uniform and neat curly appearance and a beautiful curly shape, and is less likely to be tangled, thereby completing the present invention.

The hair treatment method of the present invention can make the natural curls or the direction of curls imparted to the hair by a permanent wave treatment or the like uniform and tidy to restore the appearance, and can improve the ease of handling of curls by making the hair less likely to tangle.

In this case, the steps [ A-1], [ B ] and [ C ] are performed simultaneously. In general, each step may be performed for each part of the hair to be treated in the order of step [ a-1] or step [ a-2] → step [ B ] → step [ C ], or in the order of step [ B ] → step [ a-1] or step [ a-2] → step [ C ].

[ Process [ c1 ]: step of setting Hair after step [ C ]

After the step [ C ], the hair may be rinsed or not rinsed, and the rinsing is preferably performed in view of making the treated hair have a good texture such as lightness and less entanglement. The present invention may further comprise a step of washing the hair after the step [ C ].

In the case of rinsing the hair after the step [ C ], it is preferable to perform the following step [ C1] between the step [ C ] and the step of rinsing the hair from the viewpoint of sufficiently obtaining the effects of the present invention.

Step [ c1 ]: leaving the hair to which the third hair treatment agent has been applied in step [ C ] at 15 to 100 ℃ for 1 to 60 minutes

The temperature at the time of leaving in the step [ c1] is 15 ℃ or more and 100 ℃ or less, preferably 60 ℃ or less, and more preferably 30 ℃ or less. In terms of ease of handling without requiring a special device at the time of hair treatment, it is preferably 15 ℃ or higher and less than 30 ℃, that is, room temperature. On the other hand, from the viewpoint of further shortening the standing time, the standing may be performed while heating with a heater or the like, and the temperature in this case is preferably 30 ℃ or more, more preferably 40 ℃ or more, and preferably 100 ℃ or less, more preferably 60 ℃ or less, and further preferably 45 ℃ or less.

The time for leaving in the step [ C1] after the third hair treatment agent is applied in the step [ C ], is 1 minute or more, preferably 3 minutes or more, more preferably 5 minutes or more, and 60 minutes or less, preferably 45 minutes or less, more preferably 30 minutes or less, from the viewpoint of relaxing irregular hair, imparting a soft touch to hair, straightening the hair of hair, and imparting manageability. In the case where the standing is performed while heating with a heater or the like as described above, the standing time can be further shortened, and the standing time in this case is 1 minute or more, preferably 3 minutes or more, more preferably 5 minutes or more, further preferably 10 minutes or more, and preferably 30 minutes or less, more preferably 15 minutes or less.

In the present invention, the standing time in the step [ C1] means the time after the third hair treatment agent is applied to the hair in the step [ C ] until the next step, i.e., a step other than the standing step.

In general, it is advantageous that the penetration of the ingredients into the hair is carried out under heating for a long time, but the present invention is excellent in that the effects of the present invention can be obtained even when the hair is left at room temperature for a short time. In the hair treatment method of the present invention, it is presumed that such an effect can be obtained by applying the second hair treatment agent to the hair in advance in the step [ B ] to change the characteristics of the hair and promote penetration of the component (C) into the hair.

The step [ c1] is preferably performed in an environment in which evaporation of water is suppressed. Specific examples of the method for suppressing the evaporation of water include a method of covering hair to which the third hair treatment agent is applied with a plastic film, cap, or the like, and a method of continuously spraying water vapor such as superheated water vapor to hair.

When the step of rinsing the hair is performed after the step [ c1], the step of rinsing the hair may be included thereafter. In the case of including a step of washing hair, commercially available shampoos and the like can be used for washing. The hair may be treated with a commercially available conditioner, or the like after washing.

After the step of rinsing the hair, the hair may be dried or may not be dried, and from the viewpoint of preventing damage to the hair, drying is more preferable. The drying may be performed by natural drying, heat drying with a blower or the like, and from the viewpoint of shortening the treatment time, heat drying is preferable. In addition, from the viewpoint of further improving the manageability and preventing hair damage, it is preferable to disentangle the hair by using a tool such as a hand, a comb, or a brush appropriately before and/or after the drying step.

The hair treatment method of the present invention is a technique capable of aligning the phase of curling of hair based on a completely different principle from a permanent wave treatment using a reducing agent or a so-called straight hair treatment using a strongly alkaline hair treatment agent, and therefore does not include a step of applying a hair treatment agent containing a reducing agent or a hair treatment agent having a pH of 12 to 14 to hair. Therefore, the hair treatment method of the present invention can deform hair without damaging the hair.

With respect to the above-described embodiments, preferred embodiments of the present invention are further disclosed below.
