I am not satisfied at all. They neither strengthened my hair nor do they smell particularly. Maybe after washing they are a little bit smoother but not straight at all

3 stars because I don't know the result after a while

as for the scent mentioned in the comments, it's not nice at all...
I have another keratin treatment in mind that is much, much better with an incredible scent... and a better shampoo... I think I won't buy this one again even if the other one is 20€ more

My hair has suffered a lot from highlights and poor management by 2 hairdressers. I have tried so many products...cheap and expensive...I didn't see a difference. With this line, I am shocked. They are amazing products. My hair is soft and silky. The color shines too. Incredible. I haven't felt them like this in years.

I got it because I recently dyed my hair and it got quite damaged. Although after several washes (5 to 7) the hair has softened a lot and is easier to style. There was no keratin treatment prior to the hair, so for treatment on damaged hair, it is just what I needed. I mainly use the shampoo and the conditioner, the oil and the spray not so much because I didn't see a big difference.

It's the third time I buy the set. My hair is curly and I style it with a hairdryer and straightener. It helps them straighten more easily and they are also very soft.

I used them years ago..and I loved them. The scent is perfect.
After several years.. I want to see if they are still as effective. They soften the hair.

I have oily hair and I have no problem with these products. On the contrary, I have seen an improvement in the health of my hair and when I straighten them, they look shiny. Additionally, they have an incredible scent.

Excellent range. I use it once a week and I have seen a difference in my hair. I highly recommend it unless you have oily hair, then this treatment is not for you.

They are excellent products! I have been using them for a long time and I have seen great improvement in both the health and appearance of my hair! They have a wonderful scent and make hair grow much easier since they do not break or create split ends
