✅ Proven Hair-Loss Treatments

14 hair-loss interventions in the evidence database with a positive verdict. The first 7 carry strong-to-moderate evidence (S, A, or B tier) — these are the evidence-based shortlist for androgenetic alopecia and related conditions. The remaining 7 carry modest evidence with a positive direction (C tier) — worth knowing about but not the first lever to pull.

Tier guide: S = strong evidence (≥3 meta-analyses agree). A = moderate (≥1 MA + ≥3 consistent RCTs). B = preliminary (small RCTs, direction consistent). C = modest (mechanism plausible + scattered human studies). Status "Published with Warning" means the conclusion is positive but the engine flagged something — usually a side-effect profile, off-label use, or limited subgroup.
