A cosmetic composition comprising, in a cosmetically acceptable medium, one or more imines not containing a hydroxide group; the medium and imine being so chosen that the imine reacts on the cystines of keratinic fibers by beta-elimination to produce dehydro-alanine and leads to the formation of lanthionine in order to produce permanent hair straightening in less than 60 minutes. Independent claims are included for: (1) a kit comprising at least two compartments one of which contains the claimed composition and another a supplementary care, conditioning, makeup, de-makeup, protection, cleansing or washing composition for keratinic fibers; (2) A method of permanent straightening of keratinic fibers employing the claimed composition; (3) Use of an imine not containing a hydroxide group as an active agent in the permanent straightening of keratinic fibers; (4) an active agent for permanently straightening keratinic fibers comprising the imine. |
