This video here is about making a messy hair bun. First the hair is drawn into a ponytail. Then, using a thick rubber-band, insert the the middle of the ponytail partially into the rubber-band so as to make a loop. Then spread the hair strands of this loop to make it look messy. Now from this spread loop, take bunches of strands and lift it slightly upwards and fix it using a hairpin. Fix the hairpins firmly so that they stay in the place. Spread out this bun from the middle. Curl up or tuck in the hair below the bun.
