The primary objective of the study was to assess the efficacy of DA-OTC-002 as a topical cosmetic hair treatment. The investigators conducted a prospective, institution-level, interventional, single-blinded, placebo-controlled investigation to assess the efficacy of a combination an alpha-1 agonist and a TAAR receptor agonist (DA-OTC-002) as a topical cosmetic hair treatment.
76 female subjects were included in the study. Subjects were otherwise healthy females, aged 18 years are older, and had ample hair on the scalp to allow application of test article. Subjects with an interfering dermatologic disease or procedure, who were pregnant, lactating, or planning to become pregnant during the study, had experienced a clinically important medical event within 90 days of the visit, who were actively treated for hypertension, or had known allergies to any excipient in DA-OTC-002 were excluded from the study. This study was conducted in compliance with Good Clinical Practice, including the archival of essential documents. All subjects gave informed consent during the study enrollment.
