Omega-3 Fatty Acids for Androgenetic Alopecia
A Strong Evidence Multiple large clinical trials consistently show significant benefits.Based on 71 studies (8 meta-analyses, 9 RCTs) with 19,624 total participants. 58/71 studies show positive effects.
The Bottom Line
Research suggests that omega-3 fatty acids may support hair health as part of a broader nutritional approach to androgenetic alopecia, though they are rarely studied as a standalone solution.
- 71 studies with nearly 20,000 participants, including 8 meta-analyses
- 82% of studies show positive effects on hair health
- Typically studied as part of multi-nutrient regimens rather than alone
- Anti-inflammatory properties may contribute to scalp health and hair growth
