DARK ASH BROWN
"This
is a pretty medium ash brown," says Robinson. "It makes [Katie
Holmes's] eyes sparkle." When going dark, Robinson suggests that it's
important to keep length—and height—in mind. "When you have long, dark
hair and are tall in proportion to that, it looks elegant. But if you're
petite, make sure it's not one length, because it will look
overwhelming." Layering will add movement to your hair and stop it from
hiding your face and body shape.
