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!
