To think red hair is not "unprofessional"

[HelpTheresPooballsInMyBed]

Obviously I'm not talking about natural gingers .

My colleague at work has today been reprimanded by one of the junior managers for having "inappropriate hair colour". It's not pillar box red or anything, more brown with a deep red shine, although obviously not natural, it's not "in your face", it's just purple/red/brown hair! If you're not sure what colour I mean google red purple hair.

I work as a carer for adults with additional needs and I'm not allowed to dye my hair any unnatural colour, eg, purple.

I work on project management in IT (finance sector) and I'd feel awkward with red hair. As would my boss, I think. There are some fields where I think you have to maintain a pretty conservative appearance.
