My hair had become really bad after highlights... so much so that I doubted if any mask or treatment could fix them. With just one application, they are already much better! I think it's worth its money. Besides, it doesn't require a large amount, so logically it will last for a long time!

I bought it with the intention of using it after prolonged exposure to the sun and sea water, like today, once a week for deep hydration. First application on hair with highlights at chest level, wet, generous amount throughout the length and roots. I left it on for half an hour. When I rinsed my hair, it wasn't as soft as to pass between my fingers, which happens to me with other drugstore hair masks. I dried it with protection from KMK by KONNY'S silk and saw it slightly moisturized compared to previous days, without styling. I will use it once a week and I will come back with a refreshed review. Its scent is the same as the other Olaplex products.

Perfect mask! My hair since I bought the entire series is different hair: everyone asks me what I have done. I use them all together in combination for about 2 months

Excellent product, the best hair mask I have ever used. Combined with the shampoo, I consider it to be the best for healthy, shiny, and beautiful hair!

I have no words for this amazing product. It softens and smooths as if you have just had a salon treatment. You don't even need to blow dry it. I was ready to book a keratin appointment, but thanks to this excellent mask, I will be able to postpone it for at least another 2-3 months. Buy it with closed eyes, you will see your hair transform!

So far, I have not found a mask that is competitive with Olaplex. It surpasses Moroccanoil, Kerastase, Redken, Macadamia (all the ones I have tried) by far. It is worth every euro!

Very good product. After the third application, there was no longer any trace of split ends in the hair. Very soft, shiny, and with nice movement.
