Sorry to hear you've being having such a tough time with it.
I completely understand about not wanting to leave the house it's so awful when it's on your face, especially because you cant do anything to hide it

I'm currently on Eumovate ointment for my face and neck and also Protopic 0.1% to try also for face and neck I tried it a few days ago but I think it may have given me a bad reaction as it made my neck feel like it was on fire and burning so I haven't used it since.
I don't have any treatments for my scalp at the moment other than having bath every third night and scratching scales off with my nails and then with a metal tooth comb (hurts like hell and takes 2hrs!)
I've only just recently started seeing dermatologist again, prior to now I last saw one when I was 15 went through every topical treatment they could give me in every strength but after only a year was told it wasn't worth me continuing to go anymore so I haven't had much help so far how about you?
