What to try next

I’ve had scalp psoriasis for quite time but it wasn’t until last year I knew what it was. I battled for a while thinking it was just dandruff until I could literally pull chunks of my scalp off daily, I finally plucked up the courage see my GP who first when down the route of multi shampoos but they had no effect. Betacap for a while seemed to calm my scalp down so I wasn’t constantly itching but it very quickly stopped working and I had multi prescriptions for antibiotics for the wounds on my head that kept becoming infected ( I really struggle not to itch) Around December I noticed a lump on my neck and by January there were 3, my GP thought they were likely linked but after finding more I went for ultrasound and was thankfully relieved to be advised they were just reactive nodes, likely due to the psoriasis on my scalp. I tend to go through stages of very small break outs of my skin but these are minor in comparison to some but over the last few months they are becoming more frequent, my fingers, thumbs and ankles are now heavy cracked as are patches on my legs and thighs. My arms seem to be under control. I’ve tried Exorex but this doesn’t seem to help either. I’m currently using dovobet for my scalp which does calm the itching to a degree but woah betide if I skip a day. The only issue I have is that my hair looks so greasy I really struggle to wash it out which probably doesn’t help my scalp that I’m washing my hair multiple times in a morning! A few months back I woke up and couldn’t read properly as my vision was blurry and it continued so bad through the day I booked an emergency eye test but apart from dry eyes he couldn’t detect anything so referred me to an othamlogist. I was pretty dumbfounded to be told my eyes were perfectly healthy but my eyelid glands were inflamed causing my tear film to be uneven hence the blurry vision and you’ve guessed it, linked to psoriasis! I’m starting to feel a bit of a loss as I’m told it’s aggravated by stress but I don’t feel stressed. I feel like I’m being a nuisance to my GP as essentially I’m not unwell and don’t want to waste their time but my body literally feels like it’s fighting me at any given time. I no longer have flare ups my scalp is just constant, my scalp hasn’t calmed fully for over a year, the only thing I’m able to control is my eyes with daily bathing and multi eye drops throughout the day. I have medical insurance and would like to see a dermatologist but don’t want to waste their time as I don’t feel like my skin is severe enough to warrant a visit but I would love to get my scalp under control. Can anyone recommend anything they’ve used on their scalp that has helped, even if it’s something you’ve tried at home. I’ve read so many forums and taken everything harsh out from washing, soaps, shampoos, deodorants. I’ve tried all the medicated shampoos, I don’t use any products on my hair at all. The rest I can live with, I would just love to be able to wake up in a morning without the need to fine comb by hair to remove all the dead skin before washing it so many times to spend the day itching and starting the cycle over again. When my hair is dry and it’s sectioned, you can see the skin just waiting to be itched off, it’s really not a pretty look. I will try anything :) Thank you
