No better than a product of the drug

Due to the many good reviews, I've decided this hair mask to buy, because I wanted something treat my hair. I have long blond-streaked hair that tends to be brittle. Before that, I got myself getting cheap products from the drugstore. The mask leaves hair soft and smooth. I had hoped that this situation would continue for over the next washes, but this is not the case. In my view, the product is good, but not better than a conventional favorable product from the drugstore.
