An aqueous permanent wave solution employing one or more compounds for cleaving keratin interprotein disulfide bonds is enhanced by including a biocompatible 1,3-alkyldiol. Preferably from two to seven percent by weight of 2-ethyl-1,3-hexanediol or 1,3-butanediol is employed. Such compositions provide a useful neutral permanent wave solution employing ammonium thio- glycolate, the first permanent wave solution with a pH in the same acidic range as the isolectric point of hair, or a five minute permanent wave with either an acid or alkaline solution.
