Supplements for Androgenetic Alopecia

What the Research Shows

Clinical research on dietary supplements for androgenetic alopecia is limited, and few oral nutrients show a strong ability to reverse genetic hair loss. Most evidence suggests that supplements are only effective if a person has a pre-existing nutritional deficiency. For example, biotin and iron may support hair growth in individuals with proven deficiencies, but they do not treat the underlying hormonal cause of androgenetic alopecia in those with normal levels. Regarding specific botanical supplements, evidence is generally weak or conflicting. Saw palmetto is frequently marketed as a natural DHT blocker, but current clinical evidence is insufficient to prove its efficacy in regrowing hair or stopping loss. Other supplements, such as collagen or various vitamin complexes, lack high-quality, large-scale human trials to support their use for this specific condition. Overall, the strength of evidence for most over-the-counter hair supplements is weak. While some small studies suggest potential benefits, the lack of standardized dosing and rigorous methodology across the research makes it difficult to confirm any definitive clinical benefit for the general population.
