Excellent product, my hair is bleached blonde.
With the use of this particular serum, I noticed that my hair doesn't break and that the structure and appearance of the hair really changed.
Truly a very good product!!

I used it a few times after washing on wet hair. Fine hair, oily roots. In terms of reconstruction, it is very strong but exactly because it opens the cuticles and pushes out whatever is in the hair, it destroys the color. That is its job as my hairdresser told me and it is good at it. I stopped using it because it stripped my color and I didn't want that. My hairdresser told me it is for damaged blonde hair and that it is very strong. Afterwards, you definitely need conditioner as it leaves the hair rough.

My hair is curly, with fine, long strands and blonde highlights. I bought the whole range, the shampoo is very good, the mask and the leave-in mask are quite good. This particular product made my hair very hard and dry and it wouldn't detangle at all. The situation got worse the more I used it and even though I only combed my hair during washing with the conditioner and before drying with the leave-in, I couldn't detangle it and it would break. It's a shame for the money I spent, it completely disappointed me. One plus is that the range has a nice scent.

In combination with the whole series (but also with another shampoo from the same company), the hair from the second or third application is shiny, hydrated, and my ends look perfect. The truth is that individually I don't think it would work, and that's a problem because the whole series is a bit pricey to keep buying again and again. So the 4 stars are for the price, otherwise as a product it is very good

The result doesn't show immediately, but after 2-3 uses, it makes the hair look healthier and shinier. On my hairdresser's advice, I use the serum on damp hair after washing and do not rinse it out.

I would say this specific product did not help me... while the whole line is excellent, the serum I don't know, it dehydrated my hair more, and since I stopped using it, my hair has improved a lot. I definitely will not buy it again.

It takes a little time for its effectiveness to show, don't judge it by the first washes. Combined with the shampoo, it does a very good job; personally, my hair came back to life. It was very damaged, and no other product worked to such an extent.

I wasn't crazy about the product. I couldn't tell if it has any effect; I didn't see any difference. It also has an extremely unpleasant smell during application.

I bought this serum because my hair (naturally thick) had suffered quite a bit from the holidays and was dry and "thirsty." The truth is that while the hair is wet, you get disappointed because at that moment, it doesn't make them feel very soft, nor do you feel that it detangles them. However, as it stays in the hair and especially when you dry it, you see it soften, detangle, and transform. The hair after blow-drying is hydrated and shiny, as if it has undergone some treatment! So, for me, it definitely works! I recommend it and will also try the corresponding mask!

Although I didn't use the shampoo from the series, I applied this serum without any additional mask or conditioner. While my hair was wet, it didn't easily detangle and I was concerned, but its effectiveness showed during drying: my hair straightened easily with a brush, it is soft, with movement (and not sticky-dry) and has a salon-like scent!
