The Neutregena T/sal therapeautic shampoo is definitely a great choice for a psoriasis treatment .This shampoo is recommended for an itchy dried scalp due to psoriasis or eczema ..It stops the itch faster than just using the regular ,head and shoulder shampoo whch i wouldnt recommend ,the t/ sal does work on behalf of the itchy dried scalp ,but i wouldnt recommend this shampoo as a long term use . .It does leave the hair dried and frizzy ,not intended for giving the hair a moisterizing healthy ,shiny look..
