This product is truly a game changer - lives up to the bold claim
I decided to try the Grey hair treatment from GR-7 but was a little bit sceptical about it working. I put it on the areas where I had grey hair (probably just under 10% grey coverage originally) twice a day and didn't wash my hair for a week. I was totally AMAZED - by the end of the week, all the greys had gone back to my original dark brown colour! 4 weeks later, and i still use it once a week to top it up and love having my colour back!! would totally recommend. Can't believe this product isn't being shouted about more on social media!!
