Claim:
A method for slowing down hair loss and/or stimulating hair growth, comprising applying to the scalp a composition comprising at least one compound of formula (I): in which A 1 is —CH 2 OH, A 2 is —CH 2 COOH or —CH 2 —CH 2 —COOH, A 3 is —(CH 2 ) 4 —NH 2 , —(CH 2 ) 3 —NH—C(NH)NH 2 , or —(CH 2 ) 3 —NH 2 , A 4 is R 1 and R 2 are independently chosen from among the hydrogen atom, linear or branched substituted or non-substituted C 1 -C 12 alkyl groups, substituted or non-substituted linear or branched substituted or non-substituted C 7 -C 20 arylalkyl groups, R 4 CO— and R 4 COO— where R 4 is a linear or branched substituted or non-substituted C 1 -C 12 alkyl group, or a substituted or non-substituted C 7 -C 20 arylalkyl, where substitutions include OH, NH 2 and COOH, X 1 and X 2 are peptide or pseudopeptide bonds, X 3 is a radical chosen from among —CO and —CH 2 —, and R 3 is a group chosen from among —OH, —NH 2 , linear or branched alcoxy C 1 -C 12 or —NH—X 4 —CH 2 —Z, where X 4 is a linear or branched C 1 -C 12 hydrocarbon group and Z is a hydrogen atom or —OH, —CO 2 H or —CONH 2 as well as their physiologically acceptable salts.
