Welcome the new era of cellular hair beauty

Kaiseraugst (CH), 4 April 2025

As consumers increasingly seek science-backed solutions to maintain scalp and hair health, senolytic science emerges as a breakthrough approach to addressing the root causes of hair aging.

By testing their bioactives on hair follicles, dsm-firmenich discovered an ingredient that will redefine the concept of anti-aging hair care. ETERWELL™ HAIR is the first senolytic hair care ingredient designed to support hair longevity, tested on hair follicles with an exclusive model for senescent cells. It works directly on the follicles, selectively reducing these harmful cells and restarting the natural hair renewal processes.

“With ETERWELL™ HAIR, we’re powering brands to meet consumers’ expectations with a proven, sustainable ingredient that revitalizes hair from the root,” said Fabrice Guillemard, Global Associate Director of Marketing at dsm-firmenich.

In in vitro tests, ETERWELL™ HAIR demonstrated a 53% reduction in senescent cells with just 0.001% dry extract, targeted senolytic mechanism. Clinical trials showed up to 28% increase in hair density after 150 days, especially for balding volunteers. Additionally, 70% of participants saw an improvement in their Anagen/Telogen (AT) Ratio, a key marker of hair vitality.

Aligned with sustainable beauty principles, ETERWELL™ HAIR brings together science and respect for both people and the planet. Made with 100% natural ingredients, including ethically sourced Alpine blue flax, it follows green chemistry principles with organic ethanol extraction and a super-low carbon footprint – under 3 kg CO2eq/kg – keeping the environmental impact to a minimum.

ETERWELL™ HAIR combines cutting-edge science with sustainability, offering consumers a holistic, responsible and effective way to support hair longevity at every stage of life.
