Aerosol isn't for everyone, for a variety of reasons. While there are a lot of loose powder formulas without it (French cult brand Klorane also makes a great one), the pointed applicator on Verb's is my top pick for the sheer control it gives you. Sectioning hair in horizontal partings is very important, especially with loose powder formulas, to ensure the dry shampoo gets to the root, and the engineering of this bottle makes that easier.
Tip: Loose powder formulas are heavier that aerosol, so massage it in at the roots, let it sit for a few minutes, then brush out the excess.
