January 2012 in “Biomolecules & Therapeutics” This study found that Grateloupia elliptica extract may help treat hair loss by promoting dermal papilla cell proliferation, inhibiting 5α-reductase, and reducing inflammation in various cell types.
January 2016 in “Korean Journal of Pharmacognosy” This study found that Grateloupia elliptica extract may promote hair growth by activating wnt/b-catenin signaling and enhancing dermal papilla cell proliferation in rat and mouse models.
September 2025 in “Journal of Applied Biological Chemistry” In a laboratory study, Grateloupia elata extract demonstrated antioxidant and anti-aging effects by scavenging free radicals, inhibiting collagenase and elastase, increasing procollagen production, and reducing MMP-1 secretion, suggesting its potential use in functional cosmetics.
This study suggests that Grateloupia elliptica extract may promote hair growth by activating wnt/β-catenin signaling and fostering dermal papilla cell proliferation.
