WEEKS 4–8
Scalp health and shedding shift
Weeks 4–8 typically show reduced hair shedding, improved hair shaft thickness in existing hairs, and healthier scalp condition. GHK-Cu’s anti-inflammatory and antioxidant activity at the scalp begins improving the follicular environment. For patients experiencing telogen effluvium, this is the window where active shedding often begins to slow.
