The INKEY list Amino Acid Anti Gray Scalp Treatment

Hair color is determined by a pigment called melanin, which our hair follicles naturally produce. As we age the follicles make less melanin, and this causes gray hair. Free radicals also interefere with hair pigmentation.
Whilst we cannot prevent the ageing process and consequenty loss of melanin, we have created an overnight scalp treatment that helps to prevent and treat pigmentation loss. The result? Less gray hairs, when used consistently over a period of 4 months.
We have used an innovative ingredient in the formulation, DARKENYL™, which helps to reactivate and stimulate the pigment in the hair follicle, prevent gray hairs from developing by helping to reactivate the production of melanin and by controlling the levels of free radicals impacting hair pigmentation.
