This product works! BUT, you have to keep using it… I used everyday for 2 weeks, then backed off and used twice a week for about 3 weeks. After that, I have only been using once a week. Another plus is that it goes a long way, you don’t have to use much of it (I have long, very thick dark brown hair; almost black). I love this product, it definitely keeps my grey hair to a minimum and it smells great too! Thank you, Mayraki!!!
