Abstract
A process for relaxing hair in which the hair fibers undergo minimal swelling is provided, using a composition that decreases the swelling of hair fibers. Use of the composition or process decreases hair fiber swelling during the relaxing process, thereby decreasing structural damage to the hair while increasing hair fiber strength.
Claims9
A process for relaxing hair fibers comprising the steps of:
- (a) lanthionizing hair fibers with a non-reducing base;
- and
- (b) applying to the hair fibers a deswelling composition selected from the group consisting of starch, sugar and salt and further comprising a pH- decreasing agent selected from the group consisting of lactic acid and phosphoric acid.
A composition for decreasing the swelling of hair fibers comprising a component selected from the group consisting of hydrogenated starch hydrolysates, sodium lactate, glycerol, sorbitol, sucrose, glucose, fructose, magnesium sulfate, and sodium acetate and further comprising a pH- decreasing agent selected from the group consisting of lactic acid and phosphoric acid.
A composition for decreasing the swelling of hair fibers during the relaxing process comprising
- (a) between about 10 and about 95 parts by weight of a hydrogenated starch hydrolysate;
- (b) between 0.00 and about 12.00 parts by weight of a noncaustic acid;
- (c) between about 0.25 and about 5.0 parts by weight of a cationic polymer;
- and
- (d) between about 0.1 and about 5.0 parts by weight ethoxylated fatty acid.
