I wanted to LOVE this shampoo, but I have to admit I do not. I guess I was looking for more volume, and it just doesn't have it. My hair looks a little thicker, but not really worth it for the price. The shampoo left a sheen on my hair that even my hairdresser noticed. The conditioner does not help. My hair was so still so tangled after using the conditioner that I felt like I was pulling out my hair when I combed it. This shampoo and conditioner just left my hair a hot, stringy mess! I kept using it several times hoping it would get better. Now I just wish I hadn't because I can't return it. I got the thickening spray as part of my Birchbox and that was why I ordered the shampoo and conditioner. The spray is MUCH better... so if you need thickening and volume, just buy the spray.
