My hair is quite long and thick, I got this because I noticed I had lost their shine and along with new shampoos and conditioners I bought, I decided to try this as well. After using shampoo—I wash my hair twice, once is not enough—I applied it only to the roots on my scalp and left it for a minute. For those who use oil, dry shampoo, or wax in your hair, it will help a lot; it deeply cleanses what a shampoo cannot do and is also very moisturizing. I use it once a week when I put oil in my hair.
