We don't think "makeover" means straighten your hair.
CurlTalker RoseAnnaDana observes:
Just once I'd like to see a makeover show where they make a woman over and leave her curly! Why do they always cut, color, and blow straight? Then everybody oohs and ahs about how FAB their new hairdo looks. Okay I'll admit that after the makeovers they do look good, but curly is good too!
