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.

How to use


  • We  recommend  shaking  the  bottle  before  use. 
  • Use  as  an  overnight  treatment.  
  • Shake  into the palm of your hand, massage hands together,  use  your  fingertips  to  rub  into  scalp and leave on overnight. 
  • Apply enough to cover entire scalp. 
  • Wash hair as normal in the morning, if desired. 
  • Use every night for best results over a 4 month period. 
  • Best results can be observed after 4 months, so the first bottle will set you off in the right direction—but keeping consistent is key! Depending on usage, you should need between 4 to 5 bottles to keep you going for approx 4 months or over.


Just like skincare, layering your hair products is an effective way to maximise the results of your routine whilst also targeting multiple concerns. Whether it’s an itchy scalp or thinning hair, build a haircare routine that works for you and your hair and scalp goals.
