Description

  The present invention relates to a hair treatment set comprising at least an I agent and an II agent, and a hair cosmetic set comprising at least a shampoo agent and the hair treatment set.

Usually, after shampooing, treatment is performed to make the hair smooth and soft.
However, when a conventional hair treatment agent (Non-patent Document 1 etc.) is used, as the shampoo / treatment is repeated many times, the hair gradually becomes stiff and stiff, resulting in sufficiently soft and smooth hair. There was a problem that it was not finished.

  If the amount of dicaprylyl ether or phytosteryl oleate is too small, it may adversely affect the flexibility or finish of the hair, while if too much, the hair may become stiff and stiff.

  The hair treatment II agent is of a so-called “detained” type, which is not washed away (not rinsed off) after application.

  The hair cosmetic set according to the present invention comprises at least a shampoo agent and the above hair treatment set.

  The shampoo agent contains at least a cationized polymer, an amphoteric surfactant, and an anionic surfactant.

  In the shampoo agent, examples of the cationized polymer and the anionic surfactant include those exemplified in the hair treatment II agent.

One or more of these may be contained.

  The shampoo agent can further contain cationized trehalose. By containing cationized trehalose, softness can be imparted to the hair at the time of shampoo rinsing and the hair at the time of towel drying after rinsing.

  The shampoo agent may further contain polyhydric alcohols (such as those exemplified in the hair treatment I agent) and nonionic surfactants (such as those exemplified in the hair treatment II agent) as additives.

  In the composition of the shampoo agent, the cationic polymer is 0.01 to 1.0 (preferably 0.1 to 0.6)% by weight, and the amphoteric surfactant is 1.0 to 15.0 (preferably 2.0). ~ 10.0)% by weight, and 1.0 to 30.0 (preferably 2.0 to 20.0)% by weight of anionic surfactant. The cationized trehalose is preferably 0.01 to 0.5 (particularly 0.05 to 0.3)% by weight.

  If the amount of the cationized polymer is too small, creaking may occur during rinsing and the feel may be impaired. Conversely, if too much, the hair may become stiff and stiff.

  When there are too few amphoteric surfactants, a soft feeling cannot be acquired and hardness may arise. On the other hand, if the amount is too large, stickiness may occur and the feel may be impaired.

  When there are too few anionic surfactants, sufficient washing | cleaning property will not be acquired and the performance as a shampoo will not be acquired. On the other hand, if the amount is too large, the detergency becomes too strong and the skin may be irritated.

  If there is too much cationized trehalose, the hair may become stiff.
