What we cover at Regrowth Index, an independent, evidence-based reference for the full hair loss landscape.

Conditions and causes. Pattern hair loss, telogen effluvium, alopecia areata, scarring alopecias, postpartum, and the hormonal/nutritional/medical drivers behind them.

Diagnosis. How to identify what kind of hair loss you have, when to see a dermatologist, what blood tests are worth requesting.

Treatments. Pharmaceuticals, procedures, devices, supplements, and lifestyle interventions, with honest assessment of efficacy and side-effect profiles.

Every meaningful claim is cited to a primary source: randomised trials, systematic reviews, dermatology society guidelines, FDA documentation. We don’t accept payment to feature, rank, or recommend any product.
