Olive Oil...

We've begun rubbing olive oil on their scalps since they had the shave, reason being that their scalps were a bit dry, and the paedaetrician told us that's the best way to treat it.

So now twice a week we rub extra virgin olive oil (the same stuff I make spaghetti bolognese with...) on their scalps before we tuck them in. Usually Friday and Saturday nights.
They don't seem to mind it, though it does make them smell like the kitchen of a mediterranean restaurant...
