I can't understand why this product gets such a low rating from many.
I have long, curly hair that I've dyed brown at home for many years (I'm naturally dark blonde). After many at-home dye jobs, my hair has finally become dark, almost black.
I tried the bleach yesterday to lighten my hair, I didn't expect to get my natural hair color back in one go, after surely a thousand dark dye jobs over the years. The product smelled strong, but all bleaches, hair dyes, and lighteners do. I was afraid my hair would turn orange since there were a lot of red pigments in it. But I think I got a super nice brown/light brown shade. Much better than expected! My hair also smells really good, like after the hairdresser.
My hair is very porous/dry, and I was a bit afraid it would break. But you can tell that the product is gentle on the hair. I much prefer to use a gentle product several times, rather than something super strong that makes the hair break.
I think many have way too high expectations, thinking that the bleach should remove all old color in one go. It's not that simple, especially if you've dyed your hair many times. It's a process to go from dyed hair to natural hair color.
As I said, I'm very pleased that my hair became many shades lighter. I'm thinking of doing another treatment in a week.
(My hair was black from the start, so there was a significant difference! One more treatment and it will be 👌👌).
