| 摘要 |
This invention relates to a method of straightening, texturing and strengthening hair undergoing an alkaline straightening procedure and to nonacidic aqueous hair texturing and strengthening compositions for use in conjunction therewith. The texturing and strengthening compositions have a pH value from at least 8 to about 11 containing at least one water-dispersible hair texturing and strengthening agent including a quarternary nitrogen atom with at least one aliphatic alkyl group directly or indirectly bonded to the quarternary nitrogen atom, the aliphatic alkyl group having from about 3 to about 22 carbon atoms. Methods for applying the compositions in post-straightening and pre-straightening procedures are disclosed.
