I can get everything else to work but the hair. Help?

What exactly you are doing and problem(s) you're having? Just tested and it's working fine for me.

are you referring to the default hair? if you want to use a default hair, in the hair tab you'll probably see a button that says "back to hair selection" or something [it looks more like regular text though. -click it -choose the new hair you want -then choose the desired colors -scroll down to the "show on avatar" button -under the avatar, you'll have 2 options: "wear now" and "save to outfits"

If this doesn't work, there are many wigs available to choose from, with many styles and colors. and not all of them are expensive ;)

Thank you
