ABSTRACT:
A process for the permanent waving of hair in which hair wound on a mandrel is exposed to the action of a reactive waving solution containing at least one reducing agent capable of cystine cleavage to achieve cystine cleavage and the step of applying an oxidizing agent to the hair to reform the cystine bonds, is improved by contacting the hair for from about 5 to 15 minutes with the reactive waving solution to achieve a substantially-maximum cystine bond cleavage; blotting the hair to remove the reactive waving solution; and contacting the hair with a protein flow solution for a period of time sufficient to induce protein flow in the hair to achieve a desired curl configuration prior to application of the oxidizing agent to reestablish the cystine bonds to fix the curl. The protein flow solution is an aqueous protein flow solution having a pH of from about 2 to about 10. The protein flow solution is preferably an aqueous solution of at least one protein flow agent which is a polyvalent metal ion, a water-soluble hydroxyorganic compound containing up to about 4 carbon atoms, and at least one hydroxyl group or mixtures thereof.
