Well, it really depends on where you live. I can do that with backcombing and hairspray, but only if I'm inside. Step outside, and I have a very broken sideways hawk. The traditional mohawk is waay stronger.
I have the same problem when I backcomb mine. Fl has terrible humidity and it just wants to droop. D:br /> But if I super coat it with hairspray when I'm done it'll be ok... usually.
