    TLDR The supplement helps improve hair growth and reduce hair shedding.
    The study evaluated the effectiveness of a marine protein-based dietary supplement on subclinical hair thinning/loss through a multisite, double-blind, placebo-controlled clinical trial. Across different trials, participants taking the supplement showed significant improvements in hair density, thickness, and reduced hair shedding compared to the placebo group. Specifically, one trial with 96 women aged 21-55 showed a significant reduction in hair shedding within 3-6 months and an increase in mean vellus-like hair diameter after 6 months. Another trial with 74 female participants showed a 20% reduction in hair shedding and an 8% increase in vellus-like hair diameter after 6 months. The findings suggested that the supplement could be beneficial for individuals experiencing subclinical hair thinning or loss by promoting hair growth and reducing shedding.
