Rihanna's follicles are magical. They can be short and long at the same time, as they are in this long-on-top, short-on-the-underside cut (aka Skrillex hair).

In 2012, she returned to her pitch black, stick straight and long hairdo, but added an edge with the close-to-the-scalp sides.

It might be a you-know-what during the grow out phase, but it looked cool in the current.
