Abstract
A method of treating hair to reduce post-perm odor by (1) reducing the degree of reaction between a permanent wave reducing agent and a natural compound contained in hair, e.g., hair aldehydes; and/or (2) altering the malodor of products formed by the reaction of hair and a permanent wave reducing agent, during the oxidation step; and/or (3) binding a fragrance to the hair to mask any odoriferous compounds that result from reaction of a reducing agent with the hair, or from the reaction of reduced hair with an oxidizing agent; and/or (4) change the naturally occurring post-perm odor by adding a reducing agent reactant during the permanent waving process resulting in more pleasant smelling reaction products.
