See {Sexual Selection, Stasis, Runaway Selection, Dimorphism, & Human Evolution} thread for some other comments on this topic.
​
What needs to be explained as much as the length of human head hair is the sexual dimorphism in hair patterns -- it's the dimorphism that says sexual selection to me, starting with it being a signal for health\fitness as mentioned above, but then it (long head hair) is taken to the extreme condition that is the mark of fisherian runaway sexual selection in any other species.
​
Enjoy.

Re: additional note
... may be selected for no other reason than they are being selected.
​
If the selection is for the purpose of mating, it is sexual selection.
