Grecian gradual anti-graying lotion 125ml is not a dye for grey hair, but an anti-graying lotion for men based on the natural recovery of the hair's melanin.
Over the years, the hair loses its natural melanin giving way to the appearance of gray hair. It is recommended to use this lotion daily for approximately 3 weeks to get the hair to produce melanin again and recover its natural colour without the need to dye it. The result is very natural and some grey hair may remain visible.
