Wonderful explanation!

What I find particularly revealing is the bit about long hair being a sign of, among other things, youth (!!!).

This is a scientific argument that should once and for all silence those who always urge women past 30 or 40 to cut off their long hair in order to look younger.

Their reasoning is just so incredibly wrong. Regardless of the actual age, I can´t remember any woman who has ever looked younger with short hair than she did with long hair.

In fact, if you ask me, only very few exceptionally attractive and very lucky women such as Halley Berry can actually pull off short hair. And even they look much better (and younger) with long hair.
