You're always on the move, and probably living out of a suitcase! The last thing you need is a complicated hair-care routine or fussy style. For long hair, a pony can be functional and fabulous.
Go from sporty to chic with glossy, smoothed-back hair. Secure above nape and wrap a strand around the elastic. Slip on a wide black headband for an upscale take on a workout go-to.
For a glam look, knot the pony on top of your head in a loose ballerina bun. Slicked-back sophistication (try a deep side part) works for short hair, too!
