9: Do: Highlights
Adding a splash of color to just about anything is always a good idea, and your hair is no exception. Obviously we're not talking about putting hot pink streaks in your hair, but some natural highlights flatter any face, as long as they're subtle.
Here's why: Adding highlights to your hair will brighten up your face, giving it a younger and thinner look. Also, the juxtaposition of light and dark in your hair mimics stripes. Vertical stripes draw the eye up and down, making your face appear slimmer. And if your hair is flat or dull, highlights give your tresses volume and shine, which is always a good thing.
