Buys you some time before washing I have normal, wavy, med-long brown hair and do not wash my hair regularly due to it drying my hair out too much. When I straighten my hair, I will use this product on day 2. This dry shampoo will buy you about a half day before needing to at least co-washing your hair with conditioner. It does help with absorbing some oil and giving you back some volume. I will use with a focus on my roots and make sure to thoroughly brush my hair out after letting it sit for a few minutes.
