ABSTRACT:
Post permanent wave hair odor is reduced by treating the hair fiber with an aqueous bicarbonate/carbonate salt solution and then with an acidic aqueous solution. After allowing sufficient time for this lotion to penetrate the fiber, the acidic aqueous solution is directly applied to the fiber so that a reaction with the bicarbonate/carbonate salts occurs. This reaction results in the formation of gaseous carbon dioxide. Evolution of this gas from deep within, as well as the surface, of the fiber serves to release any trapped volatile malodorous mercaptans and byproducts.
