It’s absolutely unbelievable the results you get with this product! I had natural platinum hair from halfway from the top of my head forward and the back mostly my original sandy brown color for years and it looked nice. I had a lot of good comments about my gray hair buy I still felt it made me look old. I just wanted some highlights to blend in the front with the back. The contrast was too harsh in my view. So at first I applied Mayraki to create highlights here in there fearful that it would destroy my natural platinum color. For me, wherever I applied Mayraki Grey Hair, my hair turned blond immediately on the first application! The transformation was instant! I thought this would wear off in a day or two….I thought it would stain my pillowcases…. But no! I thought it would wash away so I didn’t shampoo for 3 days, but no!!! So a week later I did more streaks here and there just in case the product would damage my hair! It was the opposite, it’s like the pigment gave it life. It’s been 2 months. I now apply the product about once a week. I do it here and there to get a natural look. I have covered most of my platinum hair but if I miss some, it’s not a problem because it blends in with the new blond and everything blends in with the back of my hair which is sandy brown. I love that I can take the bottle with me when I travel and never have to worry about being at the mercy of a hair salon to look younger and most importantly I am not putting products full of chemicals on my head!
