Clinical Evaluation of a Nutraceutical Supplement (Olistic Women) for Hair Growth and Hair Loss in Human Volunteers

Hair loss is a multifactorial and complex condition influenced by factors such as hormonal changes, vitamin and mineral deficiencies, genetic predisposition, oxidative stress, aging, inflammation, and psychological stress. This 6-month randomized, double-blind, placebo-controlled study aimed to evaluate the efficacy and safety of a drinkable nutraceutical formulated with natural, high-quality, patented, and standardized ingredients designed to support hair health through multiple biological pathways. A total of 106 premenopausal women aged 18 to 40 years and diagnosed with telogen effluvium were randomized to receive either the nutraceutical (n = 53) or placebo (n = 53). The primary endpoint was the increase in hair density from baseline versus placebo. The secondary endpoint was the change in the anagen-to-catagen/telogen (A:C/T) ratio. These parameters were assessed using phototrichoscopy and phototrichogram via TrichoScan®. The study was approved by an ethics committee and conducted by two independent board-certified dermatologists at two study sites.
