## Abstract

The present invention provides a hair cosmetic composition containing the following components (a) and (b) and a hair treatment method in which the hair cosmetic composition is applied to the hair: (a) one or two or more peptides each having the number of amino acid residues being 5 to 50, and having neither a sulfur-containing amino acid residue nor a derivative thereof; and (b) a hair-swelling organic solvent.

## Claims

### Claim 1

A hair cosmetic composition, comprising:
(a) a peptide which is free of sulfur-containing amino acid residues and which
(1) consists of 20 or 22 amino acid residues;
(2) has a molecular weight of 1500 to 3500;
(3) comprises 4 or 5 basic amino acid residues;
(4) comprises 10 or 16 non-polar amino acid residues;
(5) has a C-terminal lysine residue; and
(6) has a at least 80% homology to an amino acid sequence selected from the group consisting of SEQ ID NO: 1, SEQ ID NO: 2, and SEQ ID NO: 3; and
(b) 0.1 to 5 mass % of an aromatic alcohol.

### Claim 2 (depends on 1)

The hair cosmetic composition according to claim 1, wherein the aromatic alcohol (b) is at least one of benzyl alcohol or benzyloxyethanol.

### Claim 3 (depends on 1)

The hair cosmetic composition according to claim 1, wherein the peptide (a) consists of:
the amino acid sequence of SEQ ID NO: 1.

### Claim 4 (depends on 1)

The hair cosmetic composition according to claim 1, wherein the peptide (a) consists of:
the amino acid sequence of SEQ ID NO: 2.

### Claim 5 (depends on 1)

The hair cosmetic composition according to claim 1, wherein the peptide (a) consists of:
the amino acid sequence of SEQ ID NO: 3.

### Claim 6 (depends on 1)

A hair treatment method, comprising applying the hair cosmetic composition according to claim 1 to hair.

### Claim 7 (depends on 6)

The hair treatment method according to claim 6, further comprising:
allowing the hair cosmetic composition to stand in the hair for 1 minute to 24 hours; and
thereafter washing the hair cosmetic composition from the hair.
