Search and filter this category ↗A large label amount is not a hair-growth result
Biotin is a B vitamin involved in processing carbohydrates, fats and proteins. It is widely marketed for hair, skin and nails, but deficiency is rare and benefit claims often go beyond the available clinical evidence. The most important practical detail may be its effect on some laboratory tests.
Read the evidence limits and sources
Evidence for improving hair, skin or nails in people without deficiency is limited. Small reports in specific conditions do not establish a general hair-growth benefit or validate every high-strength bottle. A higher microgram amount is not a reliable measure of cosmetic effectiveness.
