I'm starting to get itchy fingers and majorly bored with my hair, but I'm terrified to do anything to my avatar lest I should lose my beloved boob-itis. So the question! If I delete my HA to change the hair, will I still be a zombie, or am I cursed to a eternity of duckbutt?

No, I'm pretty sure you won't lose it. I don't think there is a way to delete your HA? xD; If you want to change your hair, then it only changes the hair. That's all. It won't change your zombie thing :)

You CAN make a new HA, although I'm not sure if that will get rid of the zombie-ness.

I thought you could only do that with the old HA/wardrobe system. Anyways, I change my HA hair all the time and I'm still a zombie o.o

=Just to confirm= The only way to cure or remove your zombieness is to take some Lamouracillin

You can do anything you wish in the wardrobe, it won't affect it.
