Hi Everyone, nice to meet you all.

I guess that i'm posting on here to get advice on treatments that may have worked for other people.
I've had p on my scalp for about 18 years. Throughout that time my stable has been ketaconozole shampoo. It doesn't help at all but it doesn't aggravate as much as 'normal shampoo'. I get an itchy dry scalp with most of the red plaques around the hairline.
Other treatments I tried over the years include polytar shampoo, Betnovate scalp application and Elecon scalp application.
Currently I am prescribed Cocois (although I find this hard to apply)and clobetesol shampoo (which I am starting to find a bit harsh). I have just attempted to use Dovonex for the second time but like my previous attempt it has made my scalp worse and given me a rash on the side of my face.
I guess what I was wondering is what treatments have worked for others. I feel like I need something to put the moisture back into my scalp but easier to apply than cocois.
Also, I have heard conflicting informatiion in how to deal with the plaques and flakes. I apply olive oil to my scalp for an hour at a time, or overnight and then rake off what i can using a fine tooth comb but I have also read that you shouldn't scratch the scalp as it can make matters worse.
I'd be grateful for any help you can offer.
