I happened upon this article today.

I haven't quite reached that age yet so I can't comment on whether or not it rings true for me, but I thought it was interesting.

Completely OT, but the real reason I clicked on that is because JLH's hair appears to be what my natural texture is now...except hers is all pretty and "done" and mine is a bit of a fuzzball (though it's looking better than before). Amazing how you can just wake up with curly hair one day...
