Summary

This 3-month study tests two doses of a dietary supplement containing biotin, collagen, keratin, and hyaluronic acid in 40 adults aged 21-50 with self-perceived thinning hair. Participants take either a low or high dose daily, and researchers measure hair thickness and strength using scalp imaging. The goal is to see if the supplement can improve hair growth and reduce shedding.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Biotin, Collagen, Keratin, and Hyaluronic Acid dietary supplement
What this could lead to: If it works, this could point toward an effective over-the-counter supplement option for improving hair thickness and strength in people with temporary thinning hair.
What could go wrong: This is a small, early-stage trial with only 40 participants and no placebo group, so results may not be generalizable. The supplement is not a drug and effects may be modest or due to chance.
