Abstract

This invention details a method for providing thermal protection to human hair by applying an aerosolized polymer system to the hair before heat treatment. It has been found that acrylate polymers provide good protection from the damaging affects of curling irons and straightening irons and afford improvements in the look and feel of the treated hair.

Claims (4)

1. A formulation for protecting hair from thermal damage resulting from contacting said hair with a heated surface, wherein said heated surface has a temperature of greater than about 150° C., said formulation comprising a polymer in a solvent wherein the polymer comprises greater than 10 weight percent of at least one acrylate monomer, wherein said acrylate monomer is acrylic acid or methacrylic acid, wherein the solvent is selected from the group consisting of an anhydrous alcohol, water, acetone and methyl acetate, and wherein said formulation is effective in attaining a wetting force of less than about 4.0×10 −4 mN for said hair subsequent to contacting same with said heated surface.

2. The formulation of claim 1 wherein the wetting force is less than about 3.0×10 −4 mN of the hair after the thermal process.

3. The formulation of claim 1 wherein the polymer comprises Octylacrylamide/Acrylates/Butylaminoethyl Methacrylate Copolymer.

4. The formulation of claim 1 wherein the solvent is an anhydrous alcohol.
