Hey guys, I thought the same things before trying this shampoo. I received a sample in my Birchbox and thought for sure I wouldn't like it enough to even think about paying $55!!! Lo and behold, I am actually considering buying the full size!!!!! Crazy, right? Well its THAT AWSOME! After the first use I saw a huge improvement in my hair. It was soft, shiny, manageable, smelled great, was not weighed down or greasy at all whatsoever!! It didn't feel like second day hair it felt freshly washed and nourished. Now for the cherry on top: I didn't have to use ANYTHING in my hair today after using this shampoo for the second time, i mean no products after the shower, just the Shu Umera and a regular conditioner in shower. I usually use a styling oil and/or mousse or other frizz combating products. Before, if I didn't put something in my hair post shower, my hair would be a hot mess!!! I AM IN LOVE! By the way, I have medium-long, thick, wavy hair that's breakage and frizz prone! I wouldn't recommend this shampoo to everyone but hopefully this review helps!!! xX
