You are damaging your hair. The dry shampoo that I have is like a powder substance. You just sprinkle it onto your hair and then comb it. It doesn’t feel oily or coated … it just feels clean and smells decent (after a good workout, my hair stinks cause I sweat a lot).
My hair is extremely thick and wavy. I also have to straighten my hair every time I wash it. Dry shampoo saves me time.
