- Offer a potent corticosteroid applied once daily for up to 4 weeks as initial treatment for people with scalp psoriasis. Refer to NICE CG153 for further details on treatment recommendations.
- Coal tar preparations are effective but may stain skin, hair and clothes. Do not offer coal tar based shampoos alone for the treatment of severe scalp psoriasis.
- Salicylic acid 2% may enhance loss of scale.
- Sebco® scalp ointment is a licensed alternative to coal tar pomade.
- If tar pomade (an unlicensed product) is being prescribed, it should be prescribed in “conventional proportions” which are significantly less expensive than bespoke mixtures ordered from “specials” manufacturers. The conventional proportions are:
- coal tar solution 6%, salicylic acid 2%, emulsifying ointment to 100g; pack size is 200g
- coal tar solution 10%, salicylic acid 6%, emulsifying ointment to 100g; pack size is 200g
