Here is a passage to put you off cutting your own hair (though not if you are cutting it all off, like the OP):
"Did you notice how queer his hair looked?"
"Now you mention it, I did think it looked a bit odd."
Beesley began eating toast and marmalade. Chewing angrily, he went on: "He's bought himself a pair of hair-clippers. I found them in the bathroom yesterday. Cuts his own hair now, you see. Too sodding mean to pay out his one-and-six, that's what it is. My God." This, then, was why, from the back, Johns appeared to be wearing a blatant toupee which had slipped over slightly to one side, and why, from the front, his face appeared to be surmounted by a curious helmet. Dixon was silent, thinking that Johns had at last done something he rather respected.
