I think that since I started using it, my hair is clearly much shinier and softer (in combination with other products) and it especially helps with my ends, which are usually drier. Overall, I will continue to use it and I believe it did the job for me

When I SEE COMMENTS saying that it did nothing to their hair, one thing I am sure of. That they use professional products as if they were widely consumed. That is, for example, they leave the hair cream all night or many hours on the hair while it says up to 5 minutes. I have saved my hair that they burned me, with series of Kerastase, hair that after 30 years of technical work, which never had movement, have returned.

Tragic mask, I haven't tried anything worse. I didn't have very damaged hair and yet it completely dehydrated them, to such an extent that the hair was breaking and creating split ends. I should note that during the period I was using it, I didn't put any pressure or strain on my hair, and I had already trimmed split ends before starting to use it. In order to recover my hair from the deep dehydration caused by this mask, I obviously had to go to a hair salon and undergo several hyaluronic and lipid treatments.

My hair was burned from the hair salon and I managed to grow it out as soon as I started using it. It's fantastic

I have thin, curly hair that is dyed with highlights. The shampoo and mask did not suit me as much as I expected, maybe they don't work well with my hair. They are good products, but I consider them a bit overpriced compared to the result.

I can't understand why Kerasta's saws are so expensive since they don't do anything at all! After using the entire range for a while, I simply said it doesn't suit me and I changed companies. Completely by chance, my friend told me that she wants to buy the whole range because her hairdresser recommended it to her, and the same thing happened to her, the mask and shampoo did absolutely nothing! We're wasting money!

My hair had been damaged from bleaching, and a hair salon recommended this particular company to me, which was unknown to me. Thanks to Kerastase products, I have hair today! If you have the financial means to combine the shampoo with the hair mask, it will change your hair. Personally, I was 100% satisfied and would buy it again

For 20 years, I have been dyeing my hair blonde with a 40-volume developer, and I have also done several bleaching treatments. The first time I did it at 18, my hair got damaged. The reason why is very simple: my friend's mother did it for me, using dye and bleach, and it only took about 2 hours since I had short hair back then. It was a miracle, I must say! Anyway, when I took matters into my own hands as a hairstylist, I have managed to grow my hair flawlessly to my shoulders, without any extensions. People often wonder if I have hair extensions because it looks so perfect. In conclusion, Kerastase products are the best! They prevent rather than treat.

I have damaged platinum hair from decoloration and I gave it a chance since it is a well-known and therefore expensive brand. The result is much lower than my expectations, during rinsing there is a slight feeling of softness, but as soon as they dry it feels like you've passed them through sandpaper. I would not buy it again, I believe there are much better options, and the fact that it smells nice does not cover me in any case.

I have very damaged hair from bleaching. I knew the company for a long time and that it is very expensive, but I decided to try it once to see if there is really a difference in my hair. Unfortunately, it's a waste of money. The hair is tangled and difficult to comb, something that I haven't encountered even in masks that cost 3€. It only has a nice scent, but otherwise it's not worth its money at all. I don't regret buying it because I was curious to try the company, but now I know that I don't need it anymore. I know well that its price is a marketing issue. It's much better to buy masks at 1/4 of its price

Wonderful product for very damaged hair. I use it in combination with the shampoo from the same range. I have normal to thick, blonde and damaged hair from bleaching and dyeing, and from the first use, you can see your hair smooth and shiny. For me, there is no better brand for hair care! You just need to know the needs of your hair and buy the corresponding products if you want to see results. Someone who uses products for damaged hair, for example, and their hair is normal, won't see a difference because the quality of their hair is already good, and it's like using just conditioner. We just sometimes exaggerate and choose products that are not suitable for our needs. Mask and shampoo from the same brand for better results.

While it leaves the hair soft and easy to comb, it does not provide treatment. It is like a regular conditioner....

I have normal to thick hair, with frizz, curls, and it is relatively damaged from blonde dyes and occasional highlights.
I liked it quite a bit, it moisturizes the hair a lot without weighing it down, reduces frizz to some extent, and you feel like you're giving your hair a salon treatment at home.
I would buy it again, the only downside is the price and the quantity if you have long hair.
But for medium or short hair, I definitely recommend it!

It is the most perfect mask for very damaged, dyed, and even neglected hair... It revitalizes the hair from the first application.... After regular use, the hair is perfect in combination with its serum.

I used it for the first time and I thought it would be like other common hair masks... I was really satisfied, it's an amazing mask, I would definitely buy it again and again... I loved it!!!!

I have thin hair with highlights and I was looking for a good mask for hydration. My hairdresser recommended this particular one and I bought it. Well, I wasn't crazy about it, it hydrates like all good masks, nothing more. Also, after applying it, my hair doesn't comb easily, it's tangled as if I didn't use a mask. It's too expensive for what it does.

The best mask for dehydrated hair, my hair was damaged from bleaching and the ends were very dry. From the first use, it softened and kept them hydrated. It only requires a small amount and spreads easily with a massage on the ends. Perfect scent, worth its money!

My hairdresser recommended it to me because my hair was damaged from bleaching. I have been using it for a month and I have seen a huge improvement in the hydration of my hair.

It is an amazing mask for thin and very damaged hair. It contains the ingredient of keratin. It doesn't moisturize the hair too much, but it leaves them thick and full, resulting in nourishing them. Also, due to the keratin, for those who have slightly damaged hair, this mask helps to straighten the hair. It is purely a 'therapeutic' hair mask. If someone wants a mask that leaves a silky and smooth result, this product will not satisfy them. I only use this one because I have very thin hair. Also, the product doesn't run out quickly.

Unbelievable mask, Kerastase is a guarantee, I didn't expect anything less when I bought it! I needed hydration and deep nourishment, something that this mask delivers 100%.
