I have long dry hair, thick, but fine so I have to be careful what shampoo I use to not have it weigh my hair down. This quenching shampoo by Bumble and Bumble is great for my hair!! It quenches my dry ends without weighing down the top and making my hair look flat. I still have lots of body and volume, plus it makes my hair smooth and moisturized. My hair is naturally wavy to curly, and this is the only shampoo that I can use for both curly styles as well as straight smooth styles. As a plus, it smells good too! I also use the conditioner every time I shampoo.
