Problems solved by technology

However, cationic polymers have a number of disadvantages when used alone, such as the tendency to make hair look thinner and greasy, especially when other chemical treatments are applied to the hair
In addition, amphoteric polymers have also been employed, but they also do not provide sufficient softness and detanglement when used alone

[0173] Without rinsing the hair, the beautician applied the relaxer composition to the entire head of each subject, leaving the composition on the head long enough to relax the hair as desired. Then, rinse hair well, wash with a neutralizing shampoo, rinse again, and style. Hair was evaluated before and after washing steps.

Embodiment 2

[0175] Example 2: Permanent Hair Color Pretreatment

[0176] The pretreatment of Example 1 was applied to half a head of hair by a beautician and distributed evenly, except that the composition did not contain 0.50% fragrance. It was noted that the composition applied easily to the hair. The other half of the head was left untreated. The headers of 3-bit objects are preprocessed in this way.

[0177] Without washing the hair, the beautician applies a permanent hair color composition (oxidative dye) to the entire head, leaving the composition on for at least 30 minutes to achieve the desired color. Then, rinse hair well until the rinse water is clear, then wash with a cleansing shampoo, rinse again, and let hair dry. Hair was evaluated before shampooing and after drying.

[0178] Hair after rinsing out color but before shampooing

Abstract

The present invention relates to a composition for the protection of keratinous fibers containing at least one compound chosen from ceramides and glycoceramides, at least one cationic polymer, and at least one amphoteric polymer; to a process and kit for protecting keratinous fibers from damage caused by chemical treatment by applying, prior to chemical treatment, to the keratinous fibers a leave-in composition comprising at least one compound chosen from ceramides and glycoceramides.

Description

field of invention [0001] The present invention relates to a composition for protecting keratinous fibers comprising at least one compound selected from ceramides and glycoceramides, at least one cationic polymer and at least one amphoteric polymer. The invention also relates to a method of protecting keratinous fibers with a leave-in composition comprising at least one compound selected from the group consisting of ceramides and glycoceramides. Background technique [0002] It is well known that keratinous fibers (especially human hair) are affected by the atmosphere and various chemical hair treatments (such as hair dyeing, bleaching, perming or relaxation / straightening) (especially long-term repeated use of these chemical treatments) Impaired (i.e. sensitized or weakened) to varying degrees. The hair then becomes difficult to detangle and style and also feels rough to the touch. [0003] In order to protect the hair during chemical treatment, various protective compound...
