Sporting multiple hair colors doesn't necessarily demonstrate creativity. For every stripper I see whose streaks or contrasting hair ends look good, I see at least a dozen who look awful.
To me, it usually appears that they saw something they liked on an actress or singer and thought the same effect would look as good on them. It doesn't always work out that way.
It also comes off as a kind of desperate attention-getting gimmick, like wearing shoes with blinking lights. Not a total deal breaker, but the sort of faddish thing girls do to impress each other more than anything that appeals to a customer.
