I was wondering could if anybody could make a mod so my character would be baldhead meaning know hair at please i need this for my character please.

What do you mean? There is a 'bald' haircut in the game.

If you mean changing your hair in progress, hit tilde and write showracemenu

When i mean bald meaning know hair at all not the balding and the buzzsaw hair style has hair.

1. Its "no" not "know".
2. Not having any hair would look very awkward because the texture break along the back of the head would be clearly visible.

there was a mod in fallout 3 that i used i can remember which one it was and it looked fine.

Well you might want to hunt that mod down cus it could help anyone quickly port it over if they get permission.

Probably talking about this: http://fallout3nexus.com/downloads/file.php?id=4620
A true bald hairstyle would be nice, but ultimately I don't care.
