A Headband

"Women think that if they have short hair they can wear only bobby pins and barrettes," says Karen Shelton, founder of Hairboutique.com, a beauty website based in Dallas. "But a headband will add definition and accentuate a great cut." It's also a good choice if you're trying to grow your hair out.

What to Look For: For very short hair (one to three inches), look for bands less than two inches wide. For longer bobs, thicker bands, wraps, and scarves also work.

How to Style: The key is to create volume at the crown for a flattering "halo" effect that also keeps the band in place. As you blow-dry damp hair, use your fingers to lift the pieces on the top of your head. For even more volume, tease hair at the crown. Place the band just past the hairline, brushing any bangs to the front of it.

Tip: Some headbands are destined to slip. To help a wayward one stay in place, secure it with a small bobby pin just behind each ear.
