Abstract:
A process for imparting smoothness and a permanent wave pattern to hair of varying natural curl levels comprising the steps of:(a) applying an aqueous alkaline relaxant composition, containing an alkaline hydroxide reducing agent to the hair;(b) allowing said aqueous alkaline relaxant composition to remain on the hair for a time of from about 10 minutes to about 30 minutes, which is sufficient to relax the hair fiber structure without completely straightening the hair;(c) removing said relaxant composition from the hair by shampooing the hair with a non-neutralizing shampoo and/or rinsing the hair with water;(d) applying an aqueous waving composition containing a thioglycolate reducing agent to the hair;(e) rolling the hair onto a plurality of curling rods;(f) allowing said aqueous waving composition to remain on the rodded hair for a time of from about 10 to about 30 minutes, which is sufficient to rearrange the wave pattern of the hair;(g) rinsing the rodded hair with water to remove said aqueous waving composition;(h) applying a neutralizing composition to the rodded hair in an amount and for a time sufficient to lock the wave pattern imparted by said aqueous waving composition into the hair;(i) rinsing the rodded hair with water to remove said neutralizing composition;(j) removing the curling rods from the hair; and(k) shampooing and rinsing the hair with a neutralizing shampoo and water.
