I've heard that beyond treating the scalp, one should toss any bedsheets, pillows and pillowcases, hats, scarves, and combs and brushes. After that, carpets can be scrubbed, and anything else cleaned to within a degree of its life. The little jerks like to hide there before going back to the scalp to start the cycle all over again.

Or something like that. But for goodness's sake, don't go all Britney on us! There's got to be a way or something a dermatologist can prescribe to give you some relief.
