I applied the mask exactly as the instructions said. You can see a difference from the very first use. I think it's necessary to buy the large package as with the small one, you can only have two or three applications at most. Also, I believe someone should have a severe problem to see a significant difference.

Not only would I buy it again, but now I buy it like water bottles! It works wonders literally

Great! Those of you who have left negative comments, I am sure you did not use it correctly. I have thin and fragile hair that breaks at the ends. I have used it once and the ends became like the hair we see in commercials.
The instructions are very simple. Wash with shampoo, not conditioner. Comb the well-dried hair and apply a very small amount (according to the amount of hair, I used as much as a hazelnut), rub it in your hands until it becomes white and apply it to the bottom of the hair and ends. I did nothing for 4 minutes with a timer and then applied a little leave-in conditioner and dried it. AMAZING RESULT

Hair thin, damaged for years from strong, copper dyes. Growing up, they became even more fragile, with frizz and split ends. Especially in the summer. How much money went to waste on cheap or more expensive masks. The leave-in silk helped a little.

Finally, I tried the treatment only with this mask, without its shampoo. The result is beyond my expectations! I saw frizzy ends smoothing out! The volume of my hair increasing! The quality has changed! I now got the big package to maintain them often. Thank you very much for making my hair new!!

Expensive for what it offers. I initially had the treatment done at the salon. Everything was fine until 2 days later. I bought the whole package (shampoo, mask, oil) to apply at home. HUGE MISTAKE! After a month of proper application, things went very wrong. After every wash, hair loss was massive to the point where I thought there might be a problem. STAY AWAY FROM THIS PRODUCT!!

I used it in the autumn on damaged hair and I was satisfied.

Five months later, after almost complete destruction of my hair from a bad keratin application at a well-known and reputable hair salon, it is the only product that restored my hair to an extreme degree in just 4 applications!

The best purchase I have ever made for my hair by far from all the others!

‘Εχω πολύ λεπτά μαλλιά που πριν λίγο καιρό μου έκαψαν με πρέσα στο κομμωτήριο. Όταν λέω έκαψαν, δεν μιλάω για απλή ξηρότητα, μιλάω για σοβαρό κάψιμο σε όλο το μήκος, σχεδόν από τη ρίζα. Έχω κάνει αρκετές θεραπείες με Olaplex, οι οποίες βοήθησαν αρκετά, αλλά είχα ελπίδες ότι αυτό το προϊόν θα βοηθούσε ακόμα περισσότερο. Ακολούθησα τις οδηγίες κατα γράμμα, έχω κάνει ως τώρα 4 και δεν έχω δει κανένα αποτέλεσμα. Λένε πως δεν χρειάζεται μεγάλη ποσότητα, εγώ έβαζα 4-5 αντλίες σε μεσαίου μήκους, ίσια και λίγα μαλλιά (στον ώμο) αλλά ένιωθα σαν να μην είχα βάλει τίποτα και δεν ήμουν ποτέ σίγουρη αν έχει πάει παντού. Η ποσότητα 15ml είναι πολύ μικρή κάνοντας το προϊόν πανάκριβο. Το Κ18 δεν έκανε απολύτως τί-πο-τα για τα μαλλιά μου, αντιθέτως, αν τα άφηνα χωρίς να βάλω κάποιο leave-in conditioner (μετά από τα 4 λεπτά φυσικά) ήταν ξερά σαν άχυρο. Φύκια για μεταξωτές κορδέλες. Πεταμένα λεφτά

Excellent product, I have no words. Of course, before using it, I searched for the correct way to use it and I will share the following:
Only shampoo in the bathroom, no mask, no conditioner.
Hair should be wet, not dry or damp.
One pump in the hand and rub the hands together until a white opaque texture is created.
Apply it all over the hair, if needed, but not too much product is necessary.
Leave it on for 4 minutes, do not do or apply anything else.
After the 4 minutes, apply a heat protectant gently and at the end, after styling it as you like, apply a hair oil.
I have hair damaged from bleaching and this mask changed my life. It is expensive, but look for it on sale.

Expensive but excellent. I use it once a month (for economical reasons) on hair with highlights. You wash your hair and then apply it. You wait for 4 minutes. Then I apply conditioner. You can also choose not to rinse it out, but if I don't use conditioner, my hair gets tangled

In frizzy hair, it helped a lot, I will definitely buy it again! It is the best purchase I have made for my hair!

It promises that hair recovers after burning. After 5 months of continuous use, I found that the hair continues to be burnt and only softens when using the product. However, any mask can do this, so it does not restore the hair after burning, therefore it is a terrible product

Excellent treatment and very easy to apply. Without having done the corresponding professional treatment at the hair salon, my hair improved a lot from the second application. When it finishes, I will definitely buy it again.

Amazing treatment!! What you're writing is a comment without basis.. simply because you bought a product while in reality, in order to see a difference, you need to go to the hair salon! The "mist" should be applied, which is the first stage of the treatment! If you don't go for this, you won't see results!!! The application of the mask is for maintenance at home... every hair has its own needs and your hairdresser will advise you on how often the treatment should be applied, first at the salon and then for maintenance at home!! All of you have damaged hair... you want them healthy but without putting your hand in your pocket.. come on! The proper use of the products is not evident from the first application alone, but over time, and that's what makes the difference!!

The worst thing ever!!! Many hairdressers recommended it to me. So, I decided to try it. Besides not being worth its money, at first, everything seems perfect. After the second week, it makes your hair straw-like and constantly breaks. I stopped using it, started using silk chi, and found my hair's health! Stay away!!

I have thin hair and I used the treatment for breakage. I applied it focusing on the front part where my hair is weaker and gradually all my hair broke! I almost had bangs without even cutting my hair! I stopped using it and replaced it with a professional conditioner and mask, and the elasticity returned, although I have to wait for my hair to grow longer. Unacceptable product and very expensive!

Tremendous product for damaged hair from bleaching, I have seen a tremendous difference in my hair, as long as you know how to use it correctly

Immediately after use, the hair is soft, but the more I used it, I noticed that it became dry, especially the ends. I don't know if it would work for someone with a different hair type, but for mine, which is fine, it made it much worse.

I had a treatment at a hair salon once (very expensive). The result was soft hair for the first two days. The following days, they became like straw. My hair was curly and now it is undefined. It's like a mess of straw. I can't fix them at all. It has already been 3 months since the treatment and it seems like there is no hope for them to recover anymore.

Um, very good product I have to say, my hair was typically damaged from bleaching. The only thing is, I bought the small amount of ml to try it out because it is an expensive product, but even with just that, I saw a little difference. Imagine if I used more ml and more times. I recommend it girls, I think you will see a difference!!!!

To me, from the moment I used it, it felt like it burned my hair. I was shocked, my hair became worse than ever and I am still trying to fix them.

I tried it once on a Saturday, thinking I would see a miracle as they say. The hair was terrible, like straw. I washed it on Monday or Tuesday, I don't remember, and put it again as they say, the hair was slightly better, not straw-like at least. The next day, it was dry again. There was a little bit left for one more time, but I will not use this awful mask treatment again, as they called it. I followed the instructions as they said. I look at the bottle and I get upset. I would give it away, but I would at least get a spray treatment from another brand. I have never been so impressed with a hair product so quickly. The first time I saw the advertisement, I was convinced. It's a tragic product

My hair was damaged after chemical treatments at the hair salon, but luckily I tried k18 and my hair was restored. They stopped breaking and started growing again. The hair becomes incredibly soft and the hairstyle stays in place. Personally, I bought it a second time and will buy it again

Personally, I have used it twice at home after getting my hair dyed at the salon... initially, the hair feels very stiff and you think something is not right... but as soon as you straighten it, you see the results... shine and reconstruction, I would definitely give it a 10... my hair is visibly thicker. Now, I don't know if this result will last without frequent use... time will tell... but I would definitely buy it again.

When you apply it, your hair immediately becomes hydrated, but when you dry it, it looks dull and dry. I used it for 1 month and didn't see any difference

It leaves the hair dry and lifeless, as if you haven't put anything on it at all, only shampoo. Definitely not worth it

It doesn't soften the hair too much, but the intense restoration from chemical treatments is noticeable. I will definitely buy it again. It is not used for detangling, although I don't have such a problem. I believe it is suitable for restoring the hair structure and preventing it from looking frizzy.

After decolorizing my hair, it became very thin, the curl was ruined, and it was breaking. This specific product did a very good job, the hair returned to its previous state (thick) and it no longer breaks, and the curl has also returned. I am very satisfied and would buy it again, it's worth its money!
