Rating (out of 5): 2
Omega-3 fatty acids, particularly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), are well-known for their cardiovascular and anti-inflammatory benefits. Their use for supporting hair health is supported by some scientific evidence, though it remains limited and not wholly conclusive. Several small clinical trials and observational studies suggest that omega-3 fatty acids may help improve hair density, reduce hair loss, and enhance hair growth, likely owing to their anti-inflammatory properties and potential to nourish hair follicles. For example, a randomized, placebo-controlled study published in Journal of Cosmetic Dermatology (2015) found that a supplement containing omega-3, omega-6, and antioxidants improved hair density and reduced telogen (resting phase) hair proportion in women with female-pattern hair loss.
Additionally, omega-3s may help address scalp inflammation and dryness, which are sometimes underlying factors in hair loss or poor hair quality. However, large-scale, high-quality trials specifically isolating omega-3s' effects on hair health are lacking. Most available evidence comes from combination supplements or is based on animal models.
In summary, there is preliminary scientific support for the use of omega-3 fatty acids in promoting hair health, but the strength of evidence is modest (2 out of 5). More rigorous research is needed to determine clear efficacy and optimal dosing for this specific purpose.
