For a consumer product, it is wonderful! I did a hair decapage (long and thin hair) and I couldn't find a way to restore them. Before the mask, it took me over an hour to untangle them, resulting in my hair being wild and of poor quality. As I had gone to the supermarket for household shopping, I saw this mask on the shelves and thought that I had nothing to lose if I tried it. And truly, after the first use, I was amazed. I untangled my hair in 5 minutes, silky texture and lightweight (I also bought a corresponding conditioner that I applied immediately after the mask). It goes without saying that I will buy it again and again! It is the best thing I have tried on my hair! Before discovering it, I only used professional hair care products, now I will add these to the list of favorite products.
