A variation on the standard bun
This is based on a tutorial for a ballerina bun remixby The Beauty Department.
I ended up doing a variation and instead of braiding the hair I ended up twisting two strands of hair together because braiding your hair while upside down is very difficult to try to make it look decent.
Link to how-to:
Use a dime sized dollop of hair gel or pomade and work through hair. Separate hair into front and back sections.
