ABSTRACT:
Simultaneous permanent waving and dyeing of hair fibers is attained by incorporating a silk amino acid and a water soluble or emulsifiable silicone based compound in the permanent waving lotion and intermixing the dyestuff with the oxidizing or neutralizing composition. Preferably, the combined dyeing and neutralizing composition is adjusted to have a pH ranging between about 7 and 9. In this preferred embodiment, the hair is warmed after receiving the combined dyeing and neutralizing composition with said composition preferably being processed on the hair at a temperature ranging between 40.degree. C. and 65.degree. C. In addition, further enhanced coloring and permanent waving is attained by incorporating a lipotropic material into the dye additive composition.
