Plus it makes me bald, despite choosing a hair in the saloon. I was infected with a zombie virus from 2012 but i cured the virus today. So, is this removable? How?

Try the Healer - she might be able to fix it. Also, if that doesn't work, try in your wardrobe, it might be one makeup kit that does that effect.

It's the missing jaw from Doctor Rachelle. Try removing it here: http://subeta.net/explore/underground/doctor.php I'm not sure how this affect the hair layer, I've never tried these myself.

The baldness I think is a wardrobe error, because a few people have been reporting the hair layer not showing up in either the normal or beta wardrobes.
