Abstract
Systematic review of published evidence on biotin efficacy for hair and nail growth.
Key Findings
All reported cases of clinical improvement with biotin occurred in patients with an underlying biotin deficiency or inherited metabolic disorder; there is no evidence of benefit in healthy individuals.
Conclusions
Biotin supplementation for hair loss is only justified in documented deficiency states.
Limitations
Case reports and small series only; no randomized trials available to pool.
Supplements Studied
All reported cases of clinical improvement with biotin occurred in patients with an underlying biotin deficiency or inherited metabolic disorder; there is no evidence of benefit in healthy individuals.
Outcomes Measured
All reported cases of clinical improvement with biotin occurred in patients with an underlying biotin deficiency or inherited metabolic disorder; there is no evidence of benefit in healthy individuals.
Every case of clinical benefit occurred in patients with an underlying biotin deficiency; no evidence supported use in healthy people
Though its use as a hair and nail growth supplement is prevalent, research demonstrating the efficacy of biotin is limited.
