What it is
Nature’s Bounty Hair, Skin & Nails is a budget beauty supplement centered on biotin, with some added vitamin C and other nutrients. It is one of the most widely sold products of its kind.
The evidence
Biotin genuinely helps hair and nails only in people who are deficient, which is uncommon. For everyone else the evidence is weak. Worth knowing too: high-dose biotin can distort certain lab tests, including some thyroid and heart markers, so tell your doctor if you take it.
Who it is for
Fine as a low-cost thing to try if you are curious, but keep expectations modest. If you have real hair or nail concerns, addressing diet, health, and any underlying cause matters more than biotin.
How we researched this
- We reviewed the product’s published ingredients, dose, and third-party testing claims.
