Abstract
The present invention is directed to methods, compositions and kits for neutralizing alkaline hair. The present invention is also directed to methods, compositions and kits for straightening human hair. The methods comprise neutralizing the hair with a hair neutralizing composition comprising at least one fatty acid. The compositions comprise neutralizing compositions comprising at least one fatty acid. The kits comprise an alkali hair relaxer or components for preparing such a relaxer and the hair neutralizing compositions.
Claims41
A method of neutralizing alkaline hair comprising applying a composition comprising at least one fatty acid to the hair, wherein the at least one fatty acid is present in an amount effective to neutralize the hair.
A method of straightening human hair comprising:
- (a) applying an alkali relaxer to the hair;
- and
- (b) applying a composition comprising at least one fatty acid to the hair, wherein the at least one fatty acid is present in an amount effective to neutralize the hair.
A method of straightening human hair comprising:
- (a) applying an alkali relaxer to the hair;
- and
- (b) applying a composition comprising at least one fatty acid to the hair;
- wherein step (b) alone is effective to neutralize the hair without further application steps beyond step (b).
A hair composition comprising:
- (a) one or more fatty acids in an amount effective to neutralize alkaline hair;
- and
- (b) a vehicle chosen from a solvent, a lipid, an ester or an inert carrier or any combination thereof.
A hair composition comprising:
- (a) a natural oil containing a fatty acid;
- and
- (b) at least one additional fatty acid in an amount effective to neutralize hair that has had an alkali relaxer applied to the hair.
A kit for straightening human hair comprising:
- (a) an alkali hair relaxer or components necessary for preparing an alkali hair relaxer;
- and
- (b) a hair neutralizing composition comprising at least one of a fatty acid or a natural oil containing a fatty acid.
A method of neutralizing hair after relaxer has been applied to the hair, the method comprising the selection of a neutralizing composition comprising a vehicle and a fatty acid for application to hair, wherein the selection of the neutralizing composition is based on one or more of the following factors:
- (a) the acid value of the fatty acid;
- (b) the ability of the fatty acid to mimic the effects of fatty acids naturally present in hair;
- (c) the concentration of the fatty acid in the vehicle used to apply the fatty acid to the hair;
- (d) the quantity of the vehicle and therefore of the composition applied to the hair being neutralized;
- (e) the quantity of relaxer remaining on the hair before it is to be neutralized, including the effect of rinsing of the relaxer from the hair;
- (e) the strength or the pH of the remaining relaxer;
- (g) the period of time during which the composition remains in the hair;
- and
- (h) the hair type, texture and quality.
