Hi, thanks for the replies, Sailor and Mike. It's much appreciated! I guess my main concern is that if I shave my hair off, my head will be a very pale canvas and so any rosy cheeks will stand out more. So I quite like the contrast with my dark hair because I've a feeling it distracts attention from any redness and makes it less apparent. I'm curious what you guys think about that.
My hairstyle at the moment is just a regular short back and sides job. Any length of hair at all is enough to set off the SD, so yeah I think it'd have to be totally shaved if I wanted to do that. It's mainly a question of whether it makes me look very red and pale. And because of the skin condition, I don't really want to use moisturisers that tan my skin, unfortunately.
