Our verdicts
Women Hair Growth Nutraceutical
Nutrafol Women is the most credible of the heavily marketed hair supplements: NSF Certified for Sport, dermatologist-endorsed and supported by a controlled trial of its original formula. But it costs about $1,000 a year, hides doses in proprietary blends, and its new biotin-free formula has less published evidence. Get a diagnosis first, and try it for six months only if the budget allows.

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.
