Personally, I'm at a loss to understand why they would pass any remarks. Bald from chemo, I get - bloody rude of course, but I get it. Maybe they don't like your "choice" of style but, really? I like to think that I wouldn't have ignored it but I suspect the shock would be enough to dumbfound me.
When I went back to work, I wore a wig for the first week as my hair (post it's first after-chemo clip) was only a few mms long and a bit patchy. I couldn't stand working in the wig so the second week I went au naturel. Very short, patchy and an ugly grey colour. Eighteen hundred teenagers never batted an eyelid except for one lovely boy who complimented me on my new haircut (obviously been told at home to recognise when a woman gets her hair cut). They never knew that I had had cancer or chemo and a few hundred of them had never even met me before.
