What should happen during the makeover: Brittany has long, soft, pretty hair, but it's not very exciting. I want to see a bold, cheekbone-skimming cut that will show off the angles of her face. Dye it red, while you're at it.
What's more likely: There's no way she's going to get out without a drastic cut, but my guess is that Tyra will have Brit's hair lightened. Not a tragedy, but not very thrilling.
