A Randomized, Double-Blind, Placebo-Controlled Study to Evaluate the Safety and Efficacy of a Nutraceutical Supplement With Standardized Botanicals in Males With Thinning Hair

BackgroundHair thinning in men is a prevalent issue for which treatment oftentimes consists of a multi-modal approach. Targeting key root causes of hair thinning, such as hormones, stress, and metabolism through vitamins, minerals, and botanicals, has been shown to be effective in improving hair growth and quality in women. This approach could also be effective in improving hair growth and quality in men with thinning hair.AimsThis study investigates the safety and efficacy of a nutraceutical in improving hair growth and quality in men with thinning hair.MethodsThis was a 6-month multi-center, double-blind, randomized, placebo-controlled trial. Men aged 21-61 years old with confirmed hair thinning were included. Subjects were randomized to receive the oral supplement or placebo. The study end points included changes in blinded Global Investigator Ratings for hair growth and quality, the Men's Hair Growth Questionnaire (MHGQ), and changes in the Arizona Sexual Experience Scale (ASEX) in the active group compared to baseline and placebo.ResultsDaily intake of the nutraceutical resulted in significantly more subjects in the active group compared to the placebo rated as improved for hair growth and quality in the blinded investigator global assessments. Overall changes and responses to the MHGQ also corroborated blinded investigator ratings. There were no trends in either treatment group for changes in sexual function on the ASEX questionnaire, and the supplement was well tolerated.ConclusionsIngestion of a nutraceutical targeting key root causes of male hair thinning significantly improves hair growth and quality in men with no changes in sexual function.
