Plaque psoriasis sounds so technical when you say it out loud. What it boils down to is the fact that you’re blessed with thick scabs and flaking on your scalp and skin. People living with psoriasis understand the struggle. It’s like their own bodies are attacking them some days, with some breakouts worse than others. Get a group of psoriasis sufferers in a room together and watching them scratch their itchy scalps will make you want to join in. Stop that itch dead in its tracks with the soothing power of coal tar shampoo. It may sound gross, but coal tar is an effective treatment for itching, flaking, irritated scalps.
