Abstract
The invention provides compositions for relaxing and conditioning keratinous fibers, particularly human hair. The compositions of the present invention have a high pH, i.e., a pH greater than 10, preferably, in the range of about 11 to about 14, more preferably about 12 to about 13.5, and include as a conditioning additive a cationic guar. Surprisingly, the cationic guar maintains stability, viscosity and activity over time in the highly alkaline pH of the inventive hair relaxer and conditioning compositions of the present invention. The relaxer compositions of the present invention afford beneficial effects to the user, such as softness and ease of wet combing, and cause less damage to hair following application and use. In addition, the conditioning relaxer compositions of the present invention remain on the hair and provide lasting conditioning and relaxing effects after one or more shampoos.
