Use of GHK-Cu analogs for hair follicle enlargement and stimulation of hair growth

Methods for the design and testing of copper-peptide complexes with hair growth properties are described.

A wide variety of GHK-Cu analogs were described that increase hair follicle size and increase hair growth in mice and rats.

Stimulation of hair growth in mice and rats The details of hair stimulation by copper peptides was studied by 1) phototrichogram, 2) folliculogram (micro morphometric analysis), and 3) the rate of DNA synthesis in the follicular cells. The effects were essentially a stimulation of the follicular cell proliferation, resulting in an enlargement of the anagen follicles from vellus to terminal type (therapy) or a maintenance of the piebald terminal follicles (prevention). A SRCP (PC1020) had the effect of follicular enlargement on the back skin of fuzzy rats, covering the vellus follicles. Chemical agents and peptides affect hair growth.
