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
