Our verdicts
Optimal Solutions Hair, Skin & Nails Gummies
A cheap, pleasant-tasting and fully disclosed biotin gummy that delivers exactly what its label says. The problem is the premise: for most people without a deficiency, 2,500 mcg of biotin is unlikely to change hair, skin or nails. Buy it as a low-cost experiment if you like, and tell your clinician before any blood test.

Hair Growth Supplement
One of the better-supported hair supplements, with a transparent label and a sensible biotin dose, at a lower monthly cost than Nutrafol. The evidence is still small and company-funded and there is no third-party certification, so treat it as a three-to-six-month experiment alongside a proper diagnosis.
