A process for permanently reshaping keratin fibers comprising mixing a component A and a component B to form a reducing composition. The component A comprises at least one thiol-based reducing compound having one thiol group selected from the group consisting of thioglycolic acid and derivatives thereof, thiolactic acid and derivatives thereof, 3-mercaptopropionic acid and derivatives thereof, and cysteine and derivatives thereof, and has pH 7.0 or less and the component B comprises at least one buffer salt selected from the group consisting of carbonates, bicarbonates and carbamates, and has pH 8.0 or more, wherein at least one of the component A and component B comprises at least one disulfide compound that is further defined, and wherein the reducing composition has a pH ranging from 7.0 to 7.8 and a viscosity ranging from 500 cps to 100,000 cps. The reducing composition is then applied to the keratin fibers.

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 an extended period of time. The present invention pertains to a hair treatment method characterized by including: (1) a step for 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; (2) a step for subjecting the hair to heat treatment at 40-230° C.; and (3) a step for rinsing the hair.

A method of treating hair to reduce frizz involving the following steps: (i) prewashing the hair with water, (ii) applying a frizz reducing product to the hair using at least one of a brush and a spray, (iii) drying the hair in air, (iv) rinsing the hair with water, (v) drying the hair, (vi) applying to the hair a flat iron, and (vii) rinsing the hair with water. The frizz reducing agent used to treat hair is glyoxylic acid. The specific temperature the flat iron is set will depend on the specific hair type and degree of frizz.
