3 stars only because it doesn't foam at all, I mean not at all, and I have to literally use almost half a bottle to feel like it's cleaning my hair. Other than that, if I do that, it leaves my hair clean and ready to receive any mask or treatment. Its consistency is very watery and it runs like thick water, of course, since it doesn't contain SLS, it's logical that it doesn't foam and it's lightweight. However, I have used many SLS-free shampoos that were not as watery and produced much more foam. It confuses me, I don't know if I will buy it again. However, for anyone who has had a keratin treatment and wants a shampoo suitable to make the treatment last longer, it's good.

It leaves the hair feeling sticky, it doesn't give a nice scent. It seems like I didn't even wash it! I definitely do not recommend it :)
