Needless to say, Head & Shoulders isn’t going to do the trick.
It does not dry out or irritate the scalp, but does have a clarifying effect on the hair.
It performs best in conjunction with the accompanying African Black Soap Purifying Masque.
Salicylic acid (yes, the same product in acne/blackhead face washes) also works topically, helping to remove the thick layers of dead skin from psoriatic plaques, which allows other medications and treatments to penetrate the skin more effectively.
Both coal tar and salicylic acid are effective, but have long-term implications. In fact, it is recommended that psoriasis sufferers alternate between the two shampoos.
Unfortunately, all coal tar and salicylic acid shampoos contain sulfates, which are drying to the hair and can lead to breakage.
