Clinical verdict
Saw palmetto + biotin is a popular hair-loss combination with plausible but unproven synergy. Saw palmetto's 5α-reductase inhibition is proven for BPH, not hair loss (limited hair data). Biotin deficiency causes hair loss but supplementation only helps if deficient (rare in healthy adults). The combination hasn't been studied as a specific pair [1].
