<p>A method for the same-day permanent waving and coloring of hair ("same-day" meaning during a twenty-four period and preferably during a single session of only a few hours), which can provide to the hair improved shape retention, color receptivity, color stability, color retention, color evenness, color depth, shine, strength, softness, luster, and/or elasticity. After initial preparation (shampooing, treating with a pre-wrap, and placing on rods if the hair is to be curled), the hair is processed using a waving agent (e.g., thioglycolate), the excess is preferably removed, contacted with a first composition, the excess preferably removed, optionally but preferably contacted with a second composition, heated to dry the hair, and then contacted with a coloring composition containing an oxidative colorant and an oxidizing agent, the oxidizing agent helping develop the color and rebond the hair. The first and second compositions each contain a biologically acceptable metal (preferably a polyvalent metal, e.g., magnesium) and optionally a proteinaceous material (preferably containing cystine).</p> |
