A classic bun is a quick hairstyle for long hair. Hair buns are easy to style and only require a brush, a hair tie, and a few bobby pins.To create a classic bun, brush and gather hair at the top of the head. Using a soft band, tie hair into a ponytail. Take the ponytail and wrap it around the band, securing it with bobby pins. Use a hairspray to keep your style smooth and secure in place for the day.
