It is not uncommon to develop dryness and itch after a trip to a cold country with low humidity. The dryness of the skin can aggravate the itch and can lead to the development of eczema. Hives can also be triggered by the change in temperature and climate.
It would be useful for you now to use soap free washes and moisturize the skin regularly but if the dryness and scaling is persistent, you can visit the dermatologist who will be able help you with this problem.
Hope you had an enjoyable trip to Europe!
