yes to the Mason Pearson
makes my hair look thicker after i brush,
even while it looks smoother..
nifty trick.
but to answer the questions...
natural or plastic is fine. i just like the tortoiseshell color.
i usually brush my hair in the morning if i took a bath the night before.
combs down my cowlicks.
but right after a shower, i comb it.
in my purse, i keep a comb, just because it's more portable.
