I've noticed that whenever I try putting on an item that changes the hair of your avatar, that the hair I have selected still shows under it. Since you can't remove the hair layer, I was wondering how to get around that problem for if I ever wanted to wear a wig in the future.

If you go to the "Avatar" link in the Wardrobe you can change your hair to "Bald". This way you won't have any visible hair interfering with wigs. :)

Thanks. I guess I thought that the initial hair choice was semi-permanent.

you can also choose No Eyes and No Mouth in the Expressions below that. That way you can wear wearable eyes and lipsticks without worrying if they can cover what's beneath.

I didnt even know that. Thank you for the information.
