Yes, they will judge.

Should they? No. But they do. Just the world we live in. So you need to take that into account and make your choices from there.

And it isn't just hair. Heck, I know of someone (now gone) where I've worked that used to only want "fit" people to apply and would toss out resumes based *entirely* on looks. No fatties allowed in that club, I guess. :p
