Hi, thanks for your query.
For dry itchy skin you may do as follows:
-use a oat meal based cleanser for bathing.
-bath with luke warm water instead of hot water.
-apply a good emollient
cream containing shea butter or olive oil after bath and repeat it twice or thrice as required.
-avoid scratching as it initiates scratch-itch cycle which increases the intensity of itching. Take oral anti hisatmine like fexofenadine
or levocetrizine by prescription.
-Drink about 2-3 litres of water per day.
-You may use a calamine
lotion or over the more itchy areas as it gives a soothing effect.
Hope this helps you.
