Abstract

Peptides have been identified that bind with high affinity to hair. Peptide-based hair reagents formed by coupling a hair-binding peptide to a benefit agent are described. The peptide-based hair reagents include peptide-based hair conditioners and hair colorants. The peptide-based hair conditioners and hair colorants are comprised of at least one hair-binding peptide coupled to a hair conditioning agent or a coloring agent, respectively.
