Efficacy and Safety of Latilactobacillus Curvatus LB-P9 on Hair Health: A Randomized, Double-Blind, Placebo-Controlled Clinical Trial

This study evaluated the effects of Latilactobacillus curvatus LB-P9 on hair health in a randomized, double-blind, placebo-controlled trial with 80 participants, of which 73 completed the study. Participants taking LB-P9 supplements experienced significant improvements in hair luster, elasticity, and satisfaction compared to the placebo group, with a 19% increase in hair luster and enhanced tensile strength. No significant adverse reactions were reported, suggesting LB-P9 is a safe and effective supplement for hair health. The study highlights the potential of probiotics like LB-P9 as an alternative approach to managing hair health, though further large-scale trials are needed to confirm these findings and assess long-term effects.
