DD's itchy scalp - how to soothe?

[meditrina]

I'm sure it's not nits! I'm combing regularly anyhow, and finding nothing.

But she's intermittently complaining of being really itchy, and periodically has a scratching fit. There's no scurf. And although it doesn't exactly fit the weather, it's only come on in the last couple of weeks when it's been humid.

Any ideas what it might be?

Or if it's just one of those things, can anyone recommend anything that might help sooth it?

This won't help but my 12yr old son is complaining of exactly the same thing and has been for a few months. Definitely doesn't have head lice. GP has given a couple of different shampoos which have made no difference, neither have H&S itchy scalp or baby shampoos work. He's slightly more comfortable when hair is very short but not for long. I'm at a loss!
