Getting Rid Of Oil
The most popular purpose of dry shampoo is to hide dirt and remove oil. Powdered dry shampoo works best for blondes or ladies with highlights. Aside from hiding oil, some powders may also help to conceal dark roots on highlighted hair.
Styling
Want to get a professional-looking bun or up-do at home? Texture is key for creating an up-do, and dry shampoo powder is an easy way to create it. To prep, apply the powder in sections before you back comb; this will help to lock in the tease. Let the powder sit on the scalp for a couple of minutes before styling, combing, or blowdrying, so it can absorb your scalp's excess oils.
Volume
While dry shampoo powder is best for greasy, dirty strands, spray is best for adding volume and texture. Flip your head over and spray generously, tousling with your fingers. Follow by focusing on the roots, and then finish by spraying all over. The dry shampoo will give too-slick hair an undone, piece-y texture that looks effortless. This works, in effect, because the starch in the dry shampoo coats each strand and absorbs its excess oils, making it feel matte to the touch.
