So I went to the Hair Salon thing and tried to change my hair, but my human avatar is still bald on my profile.. When I go to my wardrobe, my hair is there.. Why? :(

Maybe you have your HA itself set to be bald? Try clicking on AVATAR and double check what you have listed for hair on your base HA and all the different expressions.

That hasn't changed anything. I don't know what I'm doing wrong here.
