Hairstyles in Singapore are intensely fun to draw. Even in a seemingly normal and boring cut, like a shaved head, there are random growths and curls emphasized by gel or other styling products. My current favourite cut looks like someone has attached a giant fluffy toupee to a normal short male haircut. Unfortunately they haven't clamped it down properly and half of it has fallen off and is alive in the wind, while the other more reasonable side is muffining over the edges of the young man's head.
I didn't quite catch that particular look here at one of my favourite food courts, but I did manage to gather quite a few examples of the asian style with my brush pen.
