in Skyrim? Thanks. If not I hope it will be added.

On PC you can type showracemenu in the console (WARNING: Don't change race, or even click on another, your stats will reset. Just change character's base appearance. That is safe.)

On consoles, you're out of luck for now.

I wonder how Bethesda could overlook such a feature. They had it in FO3 which they made. Skyrim is better in my opinion, but its just lame how they overlooked getting a haircut.

You're wearing helmets, masks and hoods pretty much all the time, never seeing your hair anyway. Now, if someone makes a mod that makes helmets invisible so you can see your character's pretty face and awesome haircut, okay, but until then it's not much of an issue.
