I've received this a couple of weeks ago and have been using it every time I've wash my hair since, twice a week, and I loved it! My hair feels a lot softer and stronger. I didn't see much change in my hair colour with it being blonde but that might just be depending on how much of the product i used each time, which wasn't very much. I would love to see how it would work for someone who has platinum or grey hair to see what colours came through. Overall I loved it and cant wait to continue using it to strengthen my hair.
