Tarsum Extra Strength Psoriasis Shampoo - Coal Tar Shampoo and Conditioner for Scalp Psoriasis, Seborrheic Dermatitis, Severe Dandruff, & Eczema - Exfoliating Relief for Flaky, & Itchy Scalp (8 oz)

Works for dandruff too, but I have scalp psoriasis and this is literally the only thing that worked. I’ve been on multiple prescription shampoos and drops, tried a million OTC shampoos. It smells absolutely terrible but within 2 washes, my severe itching was gone and about 80% of the flakes were gone. I use twice a week. https://a.co/d/09cctOt5
