Hairweave is something you do to your hair, so I'd call it a hairstyle. Skinhead is more a description of the person than the hair style, I'd call a person a skinhead, the style is a shaved head. If I were describing the hairstyle I might be going to get I could say I'm going to get a hairweave, then dreadlocks, put them in bunches and when I'm tired of it shave my head and be a skinhead.
