Hair styling method
First Claim
1. A method of styling mammalian hair, wherein said method comprises:
- either first contacting the hair for about 1 to 20 minutes with a styling-effective amount of a composition comprising a poly(vinylamine-vinylformamide) copolymer and an aqueuous carrier; and
thereafter contacting the hair for about 1 to 20 minutes with a styling-effective amount of a composition comprising a bisulfite and an aqueous carrier;
or contacting the hair for about 1 to 20 minutes with a styling effective amount of a composition comprising a bisulfite and an aqueous carrier; and
thereafter contacting the hair for about 1 to 20 minutes with a styling effective amount of a composition comprising a poly(vinylamine-vinylformamide) copolymer and an aqueous carrier; and
subsequently styling the hair by contacting the hair with a device comprising at least one flat surface at a temperature of at least about 100°
C. for at least about 1 second to at least semi-permanently straighten the hair wherein the poly(vinylamine-vinylformamide) copolymer comprises a high molecular weight poly(vinylamine-vinylformamide) copolymer, a low molecular weight poly(vinylamine-vinylformamide) copolymer, or a combination thereof and wherein the bisulfite is selected from the group consisting of bisulfite salts of sodium, bisulfite salts of potassium and bisulfite salts of calcium.

Abstract
Provided is a method for styling mammalian hair that includes contacting the hair with a composition that includes a poly(vinylamine-vinylformamide) copolymer and a first carrier, contacting the hair with a composition that includes a bisulfite and a second carrier, and styling the hair. The method of the present invention promotes improved hair styling properties such as improved curl retention and straightness retention, e.g., under conditions of high relative humidity and temperature. The method can be used for semi-permanently straightening or curling the hair. Also provided is a method for controlling fizz by applying the copolymer and bisulfite compositions.
