After so many red carpet experiences and events, many stars adopt a signature hairstyle, so when they diverge from that, they can be practically unrecognizable. Others like to mix it up all the time, trying new hairstyles and switching from curly to straight to wavy and back again, always leaving fans guessing. But no matter what their style philosophy, there are plenty of stars who just look seriously different when they switch their hairstyles between curly and straight.
These 20 celebrities look gorgeous no matter what—but they look totally different with curly and straight hair. Which hairstyle do you prefer?
