I have a hard time with dry shampoo in spray bottles, as it is often heavily perfumed, and then my hair becomes rough, and my scalp itches, and it feels like I have a layer of dried clay on my scalp. I bought this after reading reviews, and it is fantastic. I have thin, fine hair that is quite short and extremely colored. I usually wash my hair every day, which makes the color fade quickly. I pour a little into my palm and put my hands together so both get powder. Then I massage it into my scalp and hair. I start with a little so I can take more if needed. With this, I can wash every 3rd day, without my normally sensitive scalp starting to itch or looking like the butter packaging has been used for styling.
I find the scent to be discreet and fresh.
Covers with two thin layers, one layer is enough with thicker application. It's so shiny that you can see reflections in it. Stays like a rock (in combination with base and top coat). Dries quickly and is easy to remove.
