Folligen is a non-drug hair loss treatment developed by Dr. Loren Pickart. It contains copper peptide and is designed to improve scalp health, reduce irritation, and stimulate hair growth. Clinical trials showed copper peptide facilitates hair growth by stimulating dormant follicles. Folligen comes in cream, lotion, and spray forms and is intended to promote hair growth both on its own and alongside other treatments like Minoxidil. Potential downsides include allergic reactions or scalp irritation from copper peptide for some users.
