Avoid drying soaps. Use a creamy moisturizing cleanser, it contains glycerin or petrolatum.
If you have a sensitive skin type, avoid tap water, because tap water can contain minerals making skin dry.
Avoid the bubbles bath. The bubbles may contain excessive chemical ingredients. For alleviating itchy skin, opt for bath oils or oatmeal scrub creams.
Use lukewarm water and avoid hot water. Hot water robs skin of moisture and cause dry skin, so it's best to shower in lukewarm water.
If you must shower in hot water, the showering time should be short and avoid hot tub bath. The same rule applies to hand-washing.
