(HealthDay News) — A nutritional supplement with specific omega-3 and omega-6 fatty acids and antioxidants can improve hair density and reduce the telogen percentage, according to a study published online January 8 in the Journal of Cosmetic Dermatology.

Caroline Le Floc’h, from Laboratoires innéov in Asnièrs-sur Seine, France, and colleagues examined the impact on hair loss of a six-month supplementation with specific omega-3 and omega-6 fatty acids and antioxidants. Participants in the randomized study included 120 healthy females. The change in hair density on standardized photographs was assessed as the primary end point.

The researchers found that photograph assessment demonstrated a superior improvement in the supplement group after six months of treatment (P<0.001). In the supplement group, the telogen hair percentage was reduced significantly (P<0.001). Compared with the control group, the proportion of nonvellus anagen hair (>40µm) increased in the supplement group. There was an increase in the trichometer index in the supplement group, and a decrease in the control group. Most participants in the supplement group reported a reduction in hair loss (89.9% of subjects at six months), and improvement in hair diameter and hair density (86.1 and 87.3% of subjects, respectively).

“Objectively measured improvements were confirmed by the subjects’ perception of efficacy,” the authors write.
