So, as you may (or may not) know, kpop artists dye their hair a lot. Sometimes to a natural color like brown or blonde. Other times its a not-so natural color like blue or green. They look great whichever they have. But what about their /natural/ black hair?
Our first example is Exo-K. Exo usually/sometimes has at least one member with black/dark hair (D.O.).
Second, we have the other half of Exo, Exo-M! This includes former members Kris, Luhan, and Tao.
Next is BTS. Bangtan looks real nice with black hair. It's pretty hard to find pics of V with black hair. I think seeing Jungkook with blonde hair would be strange. I dunno, but he looks nice~ too.
This is just my opinion but I think they look better with their black hair. Or at least dark hair like purple. They all look great either way, so no complaints.
I would have more groups but...no. Sorry that I'm kinda biased to BTS and Exo.
