OK so headlice were my first thought, but have asked a few lucky people to check now and it's definitely not that.
Apparently there is no flaking, redness, rash or scabbing anywhere. The crown of my head just itches like fury. I'm pregnant, so possibly it is in the vast "one of those things" category.
Anyone recommend any treatments? Seem to remember a TV ad for something called T Gel, any good?
