Our Psoriasis Shampoo helps soothe itchy scalp by softening hard crusty scales and large flakes while easing the redness and itch that can be associated with psoriasis.  The large scales and flakes become soft so they can easily be removed. Tea tree, wheat protein, and neem oil work synergistically for a healthier scalp. Shampoo has a rich and creamy foamy lather that is safe for colour-treated hair.
