I've been dying my hair since the age of 17 to hide grey hairs and parts of my head are fully white now (in my early 40s). I'm never going to age gracefully and go grey, but im sick of dying my hair platinum blonde to hide the white roots.
So having been sucked in by the viva nmn marketing, I decided to give it a go. And I think it's actually working! I've been checking my parting and to my disbelief I have a load of black hairs sprouting through!
Has anyone else reversed their grey/white hair with NMN?
