At first I was very happy with the results,I used it a couple of times.. and learned for the second time not to use the third step anymore...or my hair gets back to the color I had before...so after the second time my hair was a lot lighter(fr dark brown with black ends to light brown) but after a few days got darker and darker on its own and now after like a month is back where I started...didn't damage the hair to much but the smell is still there when wet.
