Peptides have been identified that bind with high affinity to body surfaces, such as, hair, skin, nails, teeth, gums, and oral cavity surfaces. Diblock and triblock peptide-based body surface coloring reagents formed by coupling a body surface binding peptide to a pigment binding peptide, either directly or through a spacer, are described. The peptide-based body surface coloring reagents may be used in conjunction with pigments to color body surfaces. The invention relates to the field of personal care products. More specifically, the invention relates to diblock and triblock peptide-based body surface coloring reagents comprising body surface-binding peptides and pigment-binding peptides that may be used to attach pigments to body surfaces.
