Description
If your main goal is to support thicker, fuller-looking hair or reduce the appearance of thinning, AHK-Cu is often the better choice

Using them in sequence (lighter AHK-Cu spray first, followed by GHK-Curich creams or serums) allows each peptide to optimize a different aspect of skin biology

AHK-Cu is often more effective when the main concern is scalp health and hair density, especially in antithinning routines
