In the pros: it moisturizes very well without weighing down fine hair, it has a nice creamy texture which, however, turns into a very fluid consistency on the hair and requires a minimal amount to take effect. Finally, it helps a lot with styling while having a very light - somewhat masculine - scent which fortunately disappears after application.

In the cons: the price, as well as the fact that I didn't see any volume except for the excessive hydration it provides (due to hyaluronic acid). Also, I have noticed that whenever I use it, my straight hair becomes frizzy.

The mask is amazing. One of the best from Kerastase. What I like most about this mask is that it "embraces" the hair. It is thick (but creamy) yet you feel like the mask sticks to the hair. It provides incredible hydration and I simply love it

It is the first time I use a mask from the brand Kerastase, so I don't have a comparison with the other masks of the company...!!! I am very satisfied, I really felt like I was using a professional expensive product.. my hair shone from the first use.. now that I am on the third application, my hair has gained permanent shine... the scent is wonderful... as for the density, I haven't seen any significant difference yet, but it is still early!!! Personally, I found the application a bit difficult and the first time I used a relatively large amount, but it turned out it wasn't necessary... with a normal amount and a good application, the job gets done!!! I would buy it again!!!! After half a month of use, I remove one star because I didn't see it helping with the density after all!!! But it is very moisturizing and gives shine as I said!!!

This series is the best thing I have bought for my hair, it does exactly what it says. Hair is 100% denser. I used it after postpartum hair loss and I was really disappointed until I used it.
