Residue and tint. Choose a tinted version for dark hair, or one that sprays clear. White cast is the most common complaint with starch-based dry shampoos.
Format. Aerosol gives even coverage, while powder or non-aerosol formats suit sensitive users and travel. The format changes both residue and how easy it is to target the roots.
Application. Spray from the distance directed onto roots, wait a minute, then massage and brush out. Spraying too close leaves patches and buildup.
Washing frequency. Use it between washes, not as a replacement for washing. Repeated layering builds up on the scalp and can cause itching.
