New Study Shows HairAge Vitae Improves Hair Pigmentation and Reduces Grey Hair Density

Saanroo has announced the publication of a new human clinical study evaluating HairAge Vitae, its proprietary Ageratum conyzoides ingredient, for its effects on hair health, including improvements in hair pigmentation and density in adults.

Published in the peer-reviewed Journal of Cosmetology & Trichology, the 12-week open-label clinical study enrolled 65 adults with between 10% to 50% grey hair in the temporal scalp region. Participants applied a topical serum containing 0.5% HairAge Vitae twice daily, and researchers evaluated changes in grey hair density, the percentage of grey hair across multiple scalp regions, participant self-assessments of hair appearance, and safety outcomes.

The results showed that HairAge Vitae significantly reduced grey hair density while improving multiple measures of overall hair appearance, further strengthening the scientific foundation for the ingredient in topical hair care applications.

“The publication of this human clinical study represents another important step in building the scientific foundation for HairAge Vitae,” said John Quilter, CEO at Saanroo. “The findings demonstrate meaningful improvements in hair pigmentation and overall hair appearance, providing formulators with clinically substantiated evidence to support the development of innovative topical hair care products.”

The study further reported a statistically significant 15.5% reduction in grey hair density after 12 weeks of use. Researchers also observed significant reductions in the percentage of grey hair across the temporal, frontal, and vertex regions of the scalp, as well as a significant decrease in the average percentage of grey hair across all scalp regions. Participant self-assessments further reflected improvements in hair thickness and overall hair health, a darker hair appearance and a reduced appearance of grey hair. The topical formulation was well tolerated throughout the study, with no serious adverse events reported.

HairAge Vitae is a proprietary Ageratum conyzoides ingredient developed for hair care applications, available as both a topical and an oral supplement. Published human clinical research has demonstrated benefits for hair growth, hair density, and, now, grey hair appearance, providing formulators with a science-backed ingredient for hair health creams, gels, serums, capsules, tablets, powder and more.
