I used this particular shampoo in combination with the corresponding conditioner. I have dyed and thick hair. I can say that it left my hair soft without weighing it down and it could be used for frequent/daily washing. I liked it more than the CHI Deep Brilliance line which I also tried.

Top shampoo just like the moisturizer from the same company. It lathers, not like those where you waste half the bottle to realize you've washed your hair. As long as I do keratin, it will DEFINITELY be the number 1 shampoo I buy.

The best conditioner I have tried. As soon as I put it on, I already feel my hair "drinking" the keratin. But even after rinsing it off, they remain soft.

I didn't like it even though the corresponding conditioner is quite good. It's very thick, difficult to spread on the hair, which gets tangled a lot while washing, and you need a lot of cream to detangle it afterwards. I also didn't notice any particular result.

Disappointing purchase. It didn't suit my hair. I bought it because of the keratin and because it doesn't contain SLS and parabens. However, while I expected it to moisturize my hair, it leaves it dry like straw. The hair becomes dull, but I think that's because it doesn't contain SLS. I also use the conditioner from the same line, which makes my hair soft, but I'm still not satisfied as it leaves a greasiness on the scalp and I have to wash it every two days.

Bad purchase. I prefer to pay a little more and get the Metal I wanted something for the holidays that doesn't have sulfate, but this really confuses my hair, which feels like a tangled mess when rinsing, like dreadlocks, and definitely needs conditioner.

I have been using it for the past two months along with the conditioner. I wash my hair and the next day it feels like I haven't washed it for 5 days. It causes hair breakage and as a result, intense hair loss. Worse than supermarket shampoos. I would not buy it again.

I was not satisfied with the product. I have thin, dyed, damaged hair that tends to frizz, and I wanted a shampoo to hydrate it. It did not address the frizz. My hair was dull and not moisturized at all. I would not buy it again. The rest of the products in the same line are excellent!!

Leaves the hair very dry!
It caused me intense dryness to the point of making wounds on my scalp.
It seemed tempting as a professional product at a good price but ultimately it's not worth it.

I bought it because I read good reviews that it leaves the hair smooth and shiny. My hair is thick and frizzy. I didn't like the scent at all, it leaves a feeling on my hair as if they are unwashed and need to be washed in 3 days

I wanted to wait for a month of use in order to have a complete opinion. In my hair type (normal with coarse hair), the result was leaving them so soft to the point where the hair breaks. I noticed that it makes my hair oily, without having such problems before. Lastly, I observed intense dryness on my scalp, which forces me to wash them daily because they become oily

Very bad! It does not make satisfactory foam...after washing, the hair is dehydrated, dull, and 10 times more tangled.

My hair is very sensitive and tends to break. This specific shampoo left my hair dehydrated and dull.. I would not choose it again

In my case, it caused intense dryness on my skin.. It may be due to the type of my hair..

Good but it doesn't work miracles. Overpriced. There are other cheaper options for keratin that do the same.
