I observe this at an age about ten years older but in general this is a phenomenon. Yes. I have no clue why, as most women seem to answer my question not convincingly as if they do not want to tell the real reasons they have. But it isn't length only, there are ravishing, sexy, short hair cuts that do a lot of good for some women. I have trouble with the type of hair cuts that are usually more or less shapeless, uninspired or plain ugly and do nothing for looks, convenince or style. The lack of quality is often more visually compelling than the shortness as such I think. And that's just me, and I do little to have stylish hair. To put it plain: I do not understand that.
