Just a random question that some of you may stumble upon.

Amongst all the idol groups (both male and female) is there anyone who hasn't yet dyed their hair? Is there anyone who still has their natural hair colour? I know they dye their hair for style, comebacks and for trends but is there at least one idol who hasn't? It seems so common to dye your hair when being idol that I always wonder if someone has refused to or has kept their hair colour for their own reasons.

Like full on natural hair. No highlights, no dyes that are natural colours. Just plain.

I'm just curious.
