摘要：PROBLEM TO BE SOLVED: To provide a method for correcting keratin fiberssuch as hair, especially a beauty method. The present invention is a method ofstraightening keratin fibers, preferably hair, comprising the steps of (i) applying a
composition for straightening keratin fibers onto keratin fibers, and (ii) at least one In thecoating means, a step of coating the keratin fibers to which the composition is appliedand keeping the keratin fibers in a wet state, (iii) more than 100°C, preferably more than100°C and less than 210°C, more preferably 110°C to 200°C. Rectifying the wet keratinfibers with a heating iron at a temperature of ℃, (iv) removing the coating of keratinfibers, and (v) optionally rinsing and/or drying the keratin fibers And a composition forcorrecting keratin fibers, the composition comprising (a) an alkylaminosulfonic acid and atleast one compound selected from those represented by a specific chemical formula forcorrecting keratin fibers. Wherein the pH of said composition is 7.5-12.0, preferably 8.0-11.5, more preferably 8.5-11.0. The present invention can provide a long-lasting sufficientstraightening effect and conditioning effect to keratin fibers (for example, to impartsoftness and smoothness to keratin fibers), less damage than conventional orthodonticmethods, and operation. Good property (for example, processing time is short by notdrying before heating). [Selection diagram] None
