Review (5/5): Works great to volumize and add shine
This vegan alternative to a boar bristle brush does a great job volumizing unwashed hair, as well as volumizing and taming freshly washed hair (and does indeed work well for blow drying).
The only con for me isn't really a con: the white bristles show dirt easily (immediately from unwashed hair, but for the health of my hair I often go over a week in the winter, so it would be expected). Even so, it just motivates me to wash it more frequently, ergo keeping it clean and sanitary.
