ThriveCo Hair Prime Serum is a lightweight, non-sticky, odourless formula that reverses premature greying of hair to restore natural hair colour. It is a clinically efficacious innovation and contains ARCOLYS that progressively recovers the hair's natural, dark pigment by reducing oxidative stress for improved melanin production by inhibiting hair whitening by stimulating the repigmentation of grey strands from the roots without the use of colourants. A reduction of white hair density and proportion can be observed in 2.5 months, which becomes even more significant in 5 months. It works regardless of gender, imparting a younger look, and thereby increasing confidence and self-esteem. No nasties formula made from scientifically proven ingredients It is cruelty-free and a dermatologically approved anti-greying serum for daily use. Designed for both men and women.
