If u feel that dryness is causing u body itching then why don't try a Mist generating Lamp, those are easily available in Malls, specially City Lifestyle in city center and other Malls. I have heard that many people suffer from dryness here in doha and many of them have mist generating lamps in their houses to create artificial humidity. well I myself have started feeling dryness since last month and I m also thinking to buy the mist lamp.
