Abstract
A packaged, self-heating neutralizing composition for use in the second stage of a permanent waving operation comprises a first component selected from a water-soluble sulfite, bisulfite, metabisulfite or thiourea stored in one compartment of a two-compartment package and a second component comprising H.sub.2 O.sub.2 separately stored in the second compartment of said two compartment package. Just before use, the said components are mixed together with an accompanying evolution of sensible heat. The resulting mixture contains free H.sub.2 O.sub.2 in amounts of about 0.5-3 percent by weight of the composition.
