It really, really shouldn't. However, interviewers can be a conservative bunch, and I'd normally advise girls to avoid dyeing their hair blue pre-interview and to remove non-traditional piercings, so I'm not sure I could say "It'll be fine!" with 100% confidence.
If it's really important to you then don't be put off by these non-evidence-based musings. You could say you did it for charity/to support a friend/relative having chemo, but I kind of feel like lying about it is worse...
