T-gel side effect? put on arms during shower ...come out of bath, dry, and skin peeling? have scalp psoriasis - not on arms

See below: Sounds like the t-gel is not agreeing with you. You may need a different shampoo with you having scalp psoriasis. See a dermatologist if you haven't already to get some topical ointments that may help.

Irritant Dermatitis: T-gel will not make your skin peel, unless you have scrubbed the area. Shampoos and soaps have similar ingredients. The peeling should stop in a few days.
