Wear two headbands with an updo - You want to place the two thin headbands a couple inches apart, and tease your hair at the crown so that the bands are separated with volume. Pull your hair into a high ponytail, twist into a messy topknot, and pin in place.
Quick Messy Bun / Up-Do. Love this! Tried it with my curly, medium length hair (so I didnt need to do the brushing or teasing parts) and it worked really well! A nice big bun with lots of waves/texture thanks to my curls :)
Take 2 elastic bands and separate the hair into 2 ponytails, one above the other, in the back of your head. Once the ponytails are secured, take sections of each ponytail and, starting at the ends, roll them toward the head, pinning them in place with bobby pins. Roll the top ponytail first, then the bottom, leaving pieces closest to the middle for last.
