Abstract
Chemical membrane complex (CMC) in hair strands is damaged by exposure to environmental factors, and by hair processing methods that use basic solutions to permanently reshape and/or recolor hair. A CMC repair solution contains components of CMC that repair CMC while cuticle cells are lifted following coloring or perming. Hair treatment with CMC repair solution quenches reactive chemicals on hair and rebuilds damaged CMC on hair. Hair treatment with some embodiments of CMC repair solution lowers cuticle cells by reducing hair pH. Application of CMC repair solution to cuticle-lifted hair strands allows permanent hair reshaping and permanent hair coloring in a single treatment session without loss of cuticle cells or associated hair damage.
Claims18
A hair treatment solution for hair with lifted cuticles, consisting of:
- water, wherein the hair treatment solution consists of at least 5% by volume of water;
- a first branched fatty acid, wherein the hair treatment solution consists of at least 1% and not more than 20% by volume of the first branched fatty acid;
- a first unbranched fatty acid, wherein
- the first branched fatty acid consists of a terminal fatty acid having a first alkyl substituent at a first substituent position on a main chain of the first branched fatty acid, the first substituent position being not less than 15, and not more than 21, carbon atoms away from a carboxyl group carbon of a terminal carboxylic acid, and
- a main chain of the first unbranched fatty acid consists of at least 12, and not more than 25, carbon atoms, including a carboxylic acid carbon;
- and
- an acetic acid and sodium acetate buffer system.
A hair treatment solution, consisting of:
- at least 5% by volume of water;
- not less than 2% and not more than 20% by volume of a first branched fatty acid wherein
- the first branched fatty acid is a terminal fatty acid having a first alkyl substituent at a first substituent position on a main chain of the first branched fatty acid, the first substituent position being not less than 15, and not more than 21, carbon atoms away from a carboxyl group carbon of a terminal carboxylic acid;
- not less than 1% and not more than 10% by volume of the hair treatment solution of a first unbranched fatty acid wherein
- a main chain of the first unbranched fatty acid has at least 12, and not more than 25, carbon atoms, including a carboxylic acid carbon;
- and
- an acetic acid and sodium acetate buffer system.
A hair treatment solution, consisting of:
- at least 5% by volume of water;
- not less than 1% and not more than 10% by volume of a first branched fatty acid, wherein
- the first branched fatty acid is a terminal fatty acid having a first alkyl substituent at a first substituent position on a main chain of the first branched fatty acid, the first substituent position being not less than 15, and not more than 21, carbon atoms away from a carboxyl group carbon of a terminal carboxylic acid;
- not less than 1% and not more than 10% by volume of a first unbranched fatty acid wherein
- a main chain of the first unbranched fatty acid has at least 12, and not more than 25, carbon atoms, including a carboxylic acid carbon;
- and
- a buffer system consisting of a weak acid and a conjugate weak base.
