@sallsters: 2024 randomized, double-blind, placebo-controlled trial: after 12 weeks, the hydrolyzed-collagen supplement group had a 27.6% increase in total hairs counted vs placebo, but importantly, that hair-count difference was not statistically significant. The study did find a statistically significant 31.9% improvement in the clinical grading of healthy hair appearance. @Crushed Tonic #collagen #crushedtonic #protein #proteinpowder #collagen
