Rebecca Romijn looks absolutely fabulous. She is more of an actress than a model today after trading the catwalk for a movie studio, but as supermodel hairstyles go, this ranks near the top. It's just a perfect hairstyle.

Based on the hair color differences at the end of her hair, it's possible it's enhanced with extensions for fullness. The main aspect of this hairstyle design, though, that you need to get right like Rebecca is the wavy angles of the hair at the top that frame your face. The "S" shape (left) and inverted "S" on the right.
