Efficacy and safety of Latilactobacillus curvatus LB-P9 on hair health: a randomized, double-blind, placebo-controlled clinical trial

This study investigated the effects of Latilactobacillus curvatus LB-P9 on hair health through a randomized, double-blind, placebo-controlled clinical trial with 80 participants aged 18-60 years with mild to moderate hair damage. The results showed significant improvements in hair luster, elasticity, and participant satisfaction in the group receiving LB-P9 supplements compared to the placebo group. Specifically, hair luster improved by 19%, and hair tensile strength increased significantly. Participant satisfaction also improved, with no significant adverse reactions reported. The study concludes that LB-P9 supplementation may be a beneficial alternative for enhancing hair health.
