Bumble and Bumble hair powders have been around for a while but are definitely still noteworthy. Introduced to us by colleague of ours, this product can be used to cover roots or gray. The powder can be also be used in a pinch for dry cleansing. Available in white, blondish, red, brown and black, it truly can be a lifesaver.
from the Bumble and Bumble site:
"Hair powders add sexy va-va volume, extend the life of a blow-dry by absorbing excess oil and provide a dry texture that keeps pins and clips from slipping (so styles stay put). The shades enhance or shift hair color – these fantastic (and fun) forms of temporary color can be used to blend away roots between color appointments (Hallelujah!)."
