Controlling Psoriasis Itching

General measures to relieve itching of psoriasis include:

Keep your skin cool; warmth tends to make itching worse.

Wear light clothing for coolness and to avoid scratchy pressure against your skin. Avoid skin irritants in fabrics such as denim and corduroy, tight clothing, and sometimes even wool and silk. Cotton clothing is recommended as much as possible.
Launder clothing with mild soap or detergent (Dreft, Ivory Snow, certain sans-additive detergents such as Tide Free). Use no additives such as enzymes, fabric softeners. Wash new clothing prior to wearing.

Keep your skin moisturized with a light emollient recommended by your dermatologist, as dry skin tends to be more prone to itching. Moisturizers can be applied to the affected psoriasis areas as frequently as required to relieve itching, scaling and dryness. Moisturizers should also be used on the unaffected skin to reduce dryness. Moisturize therapy helps to restore one of the skin's most important functions, which is to form a barrier to prevent bacteria and viruses getting into the body and therefore help to prevent a rash becoming infected. Moisturizers are safe and rarely cause an allergic reaction.Occasionally, products with lanolin may cause a reaction. Ideally, moisturizers should be applied three to four times a day. Apply in a gentle downward motion in the direction of hair growth to prevent accumulation of cream around the hair follicle (this can cause infection of the follicle).
