Abstract
The invention concerns a method for straightening keratinous fibers including: (i) a step of applying on the keratinous fibers a hair straightening composition containing at least one alpha-hydroxy and/or keto acid derivative, the pH of said composition being not more than 9 (ii) a step of increasing the temperature of the keratinous fibers, using heating means, to a temperature ranging between 110 and 250° C.

1-14. (canceled)
A process for relaxing keratin fibers, comprising:
- applying to the keratin fibers a hair-relaxing composition comprising at least one α-hydroxy acid or keto acid derivative, wherein the pH of said composition is less than or equal to 9, and
- heating the keratin fibers to a temperature of from 110° C. to 250° C.
A kit comprising at least:
- one heating apparatus that provides a temperature of from 110° C. to 250° C.,
- at least one hair-relaxing composition comprising at least one α-hydroxy acid and/or keto acid derivative, wherein the pH of said at least one composition is less than or equal to 9.
