Regrowth Labs D5A is a topical hair regrowth treatment containing 0.5% Dutasteride and 1% Azelaic Acid. These ingredients act as 5α-reductase inhibitors, preventing the conversion of testosterone to dihydrotestosterone (DHT), which is linked to hair loss. The product also includes Propanediol, a plant-based alternative to Propylene Glycol, which enhances absorption and reduces skin irritation.
The formula incorporates Trichogen to stimulate hair growth and improve scalp microcirculation. It uses nanosome encapsulation technology and transdermal enhancers for deeper penetration. The product is free from petroleum, mineral oil, fragrance, sulfates, and parabens.
