Yes, products such as Spectral.DNC-N and Revita shampoo have active DHT blockers such as caffeine, azelaic acid, ketoconazole, emu oil and more.
CAFFEINE: Caffeine reverses the effects of dihydrotestosterone (DHT), the main hormone involved in hair loss. It is also known to increase blood circulation to the scalp and extend the anagen phase.
EMU OIL: Emu oil is rich in essential fatty acids. Over time, it can revitalize the scalp, stimulate hair growth, and decrease hair loss. Clinical studies also have shown that emu oil acts as a 5a-reductase inhibitor and reducing the DHT in the scalp.
KETOCONAZOLE: Ketoconazole has antifungal properties and is clinically proven to fight the conversion of Testosterone to DHT. It reduces scalp irritation caused by fungal colonization or infection, which is crucial to quelling the inflammatory process that occurs in male and female pattern balding.
AZELAIC ACID: This potent 5α-reductase inhibitor treats androgenic alopecia with a mechanism of action different than Minoxidil. It demonstrates higher bioavailability and a superior toxicological profile, as well as inhibiting DHT
