Hair repair composition
View Patent ↗The invention relates to a method for mending split ends of hair comprising contacting the hair with split ends with a composition comprising at least cationic polygalactomannan containing non-ionic hydroxyalkyl substituents and having a Brookfield RVT viscosity at 25° C. and 20 rpm greater than 700 mPa·s, at a concentration of 1 pbw in water, for instance comprised between 700 and 1,200 mPa·s.
1. A method for mending split ends of hair comprising contacting the hair with split ends with a composition comprising at least one cationic polygalactomannan having non-ionic hydroxyalkyl substituents and the cationic polygalactomannan having a Brookfield RVT viscosity at 25° C. and 20 rpm of greater than 700 mPa·s, at a concentration of 1 pbw in water, wherein the cationic polygalactomannan is the only component for mending split ends in the composition.
2. A method for maintaining curl retention of hair comprising contacting the hair with a composition comprising at least one cationic polygalactomannan having nonionic hydroxyalkyl substituents and the cationic polygalactomannan having a Brookfield RVT viscosity at 25° C. and 20 rpm of greater than 700 mPa·s, at a concentration of 1 pbw in water, wherein the cationic polygalactomannan is the only component for maintaining curl retention of hair in the composition.
3. A method for protecting hair color comprising contacting the hair with a composition comprising at least one cationic polygalactomannan having non-ionic hydroxyalkyl substituents and the cationic polygalactomannan having a Brookfield RVT viscosity at 25° C. and 20 rpm of greater than 700 mPa·s, at a concentration of 1 pbw in water, wherein the cationic-polygalactomannan is the only component for protecting hair color in the composition.
