Abstract

A composition comprising two peptides with a size of 11 and 12 amino acids, wherein 2-3 of said amino acids are cysteines and a suitable dermatology excipient, which can be used for treatment and grooming products for animal hair, preferably for treatment and cosmetics for human hair.

Claims (7)

1. A method for treating hair, the method comprising administering a peptide composition comprising:

a peptide consisting of

SEQ ID NO: 1 or SEQ ID NO: 2; and

an excipient.

2. The method of claim 1 , wherein the method comprises binding the peptide composition to hair.

3. The method of claim 1 , wherein the peptide composition comprises ascorbic acid, citric acid, sodium hydroxide, triethanolamine, or a combination of two or more thereof.

4. The method of claim 1 , wherein the peptide is conjugated to an acyl group.
