Abstract

The purpose of the present invention is to provide a hair treatment method that permits a suitable amount of a component having a hair treatment effect to be deposited uniformly on the hair, and that has exceptional persistence of effects in which hydrophobicity, combability, and smoothness is restored by appropriate heat treatment to hair that has been damaged and in which these effects can be maintained for a long period of time. The present invention pertains to a hair treatment method characterized by including: a step (1) of applying, to hair, a hair treatment agent containing a copolymer that includes a polysiloxane structure and a polyoxyalkylene structure in the main chain, the copolymer having a side chain that has a trialkoxysilane group or a silanol group; a step (2) of subjecting the hair to heat treatment at 40-230 DEG C; and a step (3) of washing the hair.

Description

technical field [0001] The present invention relates to hair treatment methods. More specifically, it relates to a hair treatment method capable of smoothing hair, imparting water repellency, etc., and maintaining the effect over a long period of time. Background technique [0002] Various hair care ingredients such as silicones are blended in hair washing cosmetics such as shampoos and conditioners, and hair conditioning cosmetics such as hair styling agents and hair care treatments. These hair care ingredients can absorb the damaged part of the hair to repair it, cover the hair and improve combability. [0003] In the hair treatment method aimed at the aforementioned hair care treatment, it is required to maintain the effect for a long period of time, especially when it is carried out in a hair salon or the like. [0004] However, polymers formulated as hair care ingredients in existing hair cosmetics can restore the combability of hair immediately after use, but are eas...
