Peptide Hair Growth Serum

A leave-on scalp serum with five peptides, saw palmetto, rosemary and eucalyptus extracts. One fluid ounce, fragrance free.

This is a cosmetic product and belongs alongside whatever your physician has prescribed rather than in place of it. If you are on minoxidil or finasteride, keep taking them — nothing here replaces either, and anything in this category promising faster results than a prescription is worth treating with suspicion.

A few drops to the scalp, massaged in. Selected by our physicians.
