Tressemmes marketing tries to make it seem like their products are professional grade. I don't find this to be the case. Certainly their products aren't priced as high as salon products but I think the product shows the reasons why. I tried this product because my hair isn't super straight but isn't curly ( it has a wave to it) I thought that it might bring some volume to my waves and make them look more curl like rather than messy. I used their mousse as well. I found their product to be okay but didn't make my hair feel or look any different than any other drug store available hair product.
