I had a friend who started balding in his early 20s. He had that stringy long blonde hair like a death metal guitarist (and he was a death metal guitarist). He just decided to shave it back then and move forward with that look, which he also pulled off well (he added a bad-ass
Scott Ian-style goatee).
When he had hair, he used to take his thumbs and start in front of his ears, then move them around his ear to the back of his neck in order to push his long hair back all the time. It was funny to watch him continue doing that as a continued habit for several months after having shaved his head. We'd both chuckle each time he did it.
