two grandsons... oldest and 4th oldest... have hair I would die for. Not sure it you would call it "Wavy" or "Curly" but it's VERY wavy and not kinky curly but definitely curly. The point is:
They have no need of a comb or a brush... and in fact neither uses a comb or brush. They get out of the shower, or lake, or swimming pool, whatever, and it's perfect. Doesn't need a thing done to it. Super thick, so thick I'm not sure they could get a comb thru it. And I'm not exaggerating... both went to their prom(s) without running comb or brush thru their hair. Towel dry, little hand motion, done.
