I am very happy
I am very happy, it works, at the beginning I had some hair left on my hands, but the gray hair is gone, and I must say that I was smoking cigarettes and drinking strong coffee normally. I wish I had taken pictures of my hair before and now after 21 days, and I used GR7 once a day and washed my head every 4-5 days. I recommend it, it worked for me. My natural color come back 😉
