Ever since I grew my hair out (I can put my bangs in my mouth, and my ears have gone into hiding, bahahahahaaha...anyways), I've noticed every other asian guy with long hair as well, it's still not common, but I never bothered to actually notice until I grew my hair out as well.
Short spiky seems to be the most common, next is short/close to bald, but it seems like long hair is beating'em.
And it's a learning experience, now I can sympathize with gals and why some of them take a while and even wake in the wee hours of the morning to pretty themselves up. Besides make up, wardrobe and such, hair takes a long time to dry, unless you use a hair drier.
The end.
