the most common cause of itching on the skin is due to dryness allergy and sometimes it might be due to skin allergy with multiple reasons. 
it is very important to find the cause otherwise it will not improve. 
if it is due to dry skin you can apply coconut oil again and again and if it is due to some other reasons like insect bite or drug reaction or any other pathology you can go for atarax anti itch lotion and then meaet your doctor and do not apply any type of powder or cream without medical consultation. 
give plenty of water to adrink and remain in contact with your doctor.
