As a scalp psoriasis treatment, Exorex Lotion will clean and moisturise affected skin conditions on the scalp

Scalp

Shampoo hair in the morning (or evening if you prefer) with a compatible non-irritant shampoo such as Exorex Hair and Body Shampoo.
Apply Exorex Lotion to the affected areas of the scalp and massage in lightly for a minute (again, do not worry about getting Exorex Lotion on 'good skin' - no harm will be done).
Apply Exorex Scalp Moisturiser to the affected areas of the scalp and massage in lightly for about a minute. (if you are also using Exorex Lotion on your body you may find it easier to apply the moisturiser to your scalp after applying the Exorex Lotion to the affected areas of your body).
DO NOT RINSE OFF. Repeat at midday (if at all possible) without shampooing hair.
Repeat morning regime at night. At this time you can replace Exorex Scalp Moisturiser with Exorex Moisturising Cream if you feel this would be more beneficial.
With Exorex Lotion and Exorex Scalp Moisturiser, only you will know that you are using anything. Simply put a brush/comb through your hair once dry.

NOTE: You should not apply Exorex Lotion to the body more than 3 times daily.

There is, however, no restriction in daily use of Exorex Moisturising Cream .

You may wish, therefore, to apply it in between Exorex Lotion applications to help reduce itching and irritation, maintain moisture and help remove scaling.

ALWAYS READ THE LABEL ON EXOREX LOTION.
