I’ve been using it for about 18 months now and I’m very happy with it. It took some figuring out, with all the different instructions, but now I have the perfect her team. I wash my hair first towel dry it, then apply the Mayraki grey treatment on my scalp. Let it sit for about an hour or two hours if you prefer. I also put in hair conditioning from my mid shaft down and then after an hour or two I wash everything out and I’m good usually for a week. I wash my hair twice a week so most times I put the treatment in every other wash. I get so many compliments on my hair!
