the shampoos aren't that effective but i find they regulate it. dovonex gel (blue lid instead of green) works very effectively and it doesnt have steroids so you can use it for as long

I also had severe psoriasis on my scalp, ears and neck. I mostly used a mixture of my own, because other creams did not work. It is mostly natural essential oils. Extra Virgin Olive oil, Tea Tree oil and Coconut oil, i mixed those oils to use as lotion. It really helped, especially for itching and dryness on the scalp, neck and ears. You can try that and see if it works for you.

have you tried to research for some herbal oils i used the search criteria "psoriasis herbal cure" and that gave me a list of things that can be used and bought online. My son uses an herbal oil for scalp and he says it's actually working for him he has that patches on his scalp and he also uses an herbal shampoo that works for him.

Also had servere psoriasis on my scalpeert and Beck.i mostly used dovobet gel its white cortizone.
It helps fast, you put it on in the evening en in the morning you wash it.
But you need DOVOBET GEL not the creme

My Husband was told to use Sebcur shampoo which is sold in most drugstores, Walmart Pharmacy, etc. It helps take the itch out of his scalp from psoriasis. I hope this information helps someone else.
