A video how-to for a workout-friendly hairstyle for medium-length hair.
Here's how to do a bun with a headband. First, gather your hair high on the top of your head. Twist it into a high bun and secure it with pins or an elastic. Then, mist hairspray all over to set the style. Lastly, put a headband on your head about an inch back from your hairline. After your workout, release the bun and you'll have tons of body and fullness.
