Scalp psoriasis can occur on parts of the scalp or on the whole scalp. It forms in the same way as on other parts of the body, but the hair traps the scale and stops it from being rubbed away as it would, say, on the elbows. In addition, the hair also acts as a physical barrier, obstructing the application of creams and ointments to the affected skin. The net result can be stubborn, thick, scaly plaques which require specifically formulated scalp treatments.

What are the symptoms?

Scalp psoriasis causes red patches of skin covered in thick, silvery-white scales.

Some people find the condition extremely itchy, while other cases are very mild. Severe cases can lead to hair loss, although this is usually only temporary.

What are the treatment options?

There are many treatment options that can help scalp psoriasis, but they all need to be used regularly and it's important for customers to find one that fits in with their lifestyle.

Tar shampoos, gels, ointments and creams are commonly used to treat scalp psoriasis. They may be combined with other ingredients €“ such as salicylic acid to help remove scale, or coconut oil to moisturise the skin. Examples: Pentrax Shampoo, Polytar Liquid, Meted Shampoo.

Remind customers that medicated shampoos are designed for the scalp, not the hair, so using a regular shampoo and conditioner after a scalp treatment will reduce any unpleasant smells associated with medicated shampoos.

Further treatments, such as topical steroids, are available from GPs. Severe cases should be referred to the pharmacist.
