Designed to reduce hair breakage and flood the scalp with nutrients, Nutrafol’s physician-developed formula comes recommended by Elisha Smith, an international master educator for Balmain Hair Couture and the owner of Pipton beauty boutique in North Carolina. “Scalp-focused exosome therapy is becoming the go-to for trichologists, facialists, and wellness clinics aiming to treat hair thinning, inflammation, and scalp aging from the root,” she says. For at-home treatments, this is her pick. “Nutrafol Growth Activator ensures and activates stronger, thicker hair using the power of ashwagandha exosomes, which are 150 times smaller than any other composition on the market, and are therefore able to more effectively penetrate the scalp,” she says.
Key ingredients: Ashwagandha exosomes, pea sprouts, Irish moss peptides

Our expert says: “Skinification of the scalp is a thing these days, and I’m here for it. Biotech serums like this one are outperforming traditional hair-growth formulas in both data and design.”—Elisha Smith
