Product specifications, research context, and handling information.
Dutasteride is a synthetic 4-azasteroid supplied here as a liquid research solution in an ethanol and USP propylene glycol vehicle.
Dutasteride inhibits type 1 and type 2 5-alpha-reductase, the enzymes that convert testosterone to DHT. Its mechanism acts at the level of DHT synthesis. Dutasteride pharmacology reference

The 2025 randomized Phase II trial evaluated direct scalp application of dutasteride solutions at 0.01%, 0.02%, and 0.05% w/v (0.1, 0.2, and 0.5 mg/mL). The 0.1% and 0.3% formulations listed here are two and six times the highest concentration tested, respectively. The trial does not establish safety, efficacy, or absorption for either listed formulation. Panuganti et al., 2025 Phase II trial
A separate randomized placebo-controlled study evaluated topical dutasteride alongside microneedling. Its findings apply to the combined intervention and do not establish the effects of conventional topical application alone. Sánchez-Meza et al., 2022 microneedling study
