Treatments for face and scalp

Hi everyone, This is my first post on the forum, but I've been a psoriasis sufferer for about 15 years now. I'm writing to ask about psoriasis treatments before I visit my doctor next week. I want to be prepared as in the past I’ve found it difficult to get prescribed anything useful from my GP. My question: Essentially, I’d like to know if there are any recommended treatments for treating mild psoriasis - particularly on the face and along my hairline. The positives: • I'm fortunate in having relatively mild psoriasis. I only get the occasional patch when I'm a bit stressed. I've kept clear for a while now from the neck down, using Dovobet cream (applied ~1 per week). • I live in the UK and during the summer months the sunlight is enough to keep the psoriasis away on my face (no other treatment required). The negatives: • When it’s not sunny (i.e. most of the year!) the psoriasis returns to my face. It really knocks my confidence when my nose is quite red and it’s in my eyebrows. • It's also in my hairline, especially near my ears and difficult to treat with creams. I've tried: • In the past my doctor has prescribed Nizoral for my hair but this does nothing (I think Nizoral is more of an antibacterial anyway). • I made the mistake of trying to use Dovobet on my face. But it's wayyy too strong and my skin is only now starting to thicken. Any help/guidance/advice would be greatly appreciated. PS: Also, is there any recommended way of getting referred to a dermatologist on the NHS? So far I’ve only seen my GP and the treatments require a lot of trial an error (they even insisted for years it wasn’t psoriasis). Many thanks in advance, Tom
