Summary

The Nutra Harmony "Biotin, Collagen and Keratin Beauty Complex" is an oral food/dietary supplement specifically designed to Promote hair growth for people suffering from temporary thinning hair. The main goal of this clinical trial is to evaluate the efficacy of two different doses of the study supplement (with 5,000 mcg vs 10,000 mcg biotin). A product formula with 10,000 mcg of biotin per serving was clinically tested and demonstrated results in strengthening hair and increasing hair thickness by promoting the growth of terminal hairs in subjects aged 21 to 50 years, with self-perceived thinning hair associated with poor diet, stress, and hormonal influences, compared with the placebo tablet.
