Hair color powdering is a centuries-old technique that Bumble and bumble session stylist Laurent Phillippon made modern with their multi-purposes sprays.
Use them to create instant fullness, enhance color, blend roots, add grip (when pinning up) and dry cleanse (correct over zealous product use or get an an extra day or two from a blow dry).
Directions:
Shake well before each use. Hold can 10-12 inches away from head and spray directly onto roots and hair. Let dry before shaking out excess with fingers. Brush through to distribute (or remove). Style as desired.
