Abstract: A method for styling hair comprises placing the hair in a desired configuration and applying a hair styling composition to the hair. The hair styling composition comprises a powder of a multistage polymer of a soft polymer of Tg<40° C.; and a hard polymer having a Tg>40° C., and at least 10° C. higher than the Tg of the soft polymer wherein the hard polymer forms a complete or partial shell around the soft polymer the weight ratio of hard polymer to soft polymer being 1.01:1 to 2:1. After exposure to liquid water and drying at temperatures below 100° C., a maximum thermal transition temperature of the multistage polymer in an atmosphere of 0% relative humidity that differs by 20° C. or less from the maximum thermal transition temperature in an atmosphere of 75% relative humidity.

Abstract: There is provided a powder that comprises a multistage polymer that comprises (a) at least one soft polymer having glass transition temperature of 40° C. or lower, and (b) at least one hard polymer having glass transition temperature higher than 40° C., wherein the glass transition temperature of said hard polymer is at least 10° C. higher than the glass transition temperature of said soft polymer, wherein the weight ratio of said hard polymer to said soft polymer is from 1.01:1 to 100:1, and wherein said multistage polymer, after exposure to liquid water followed by drying at temperatures below 100° C., shows maximum thermal transition temperature in an atmosphere of 0% relative humidity that differs by 20° C. or less from the maximum thermal transition temperature in an atmosphere of 75% relative humidity.

Abstract: The present invention relates to improved hair styling compositions and methods of using such compositions. More particularly, the present invention relates to hair styling compositions with improved durability performance of the hair fixative resins, including resistance to high humidity, low tackiness, and good hold.
