Sorry, yes oatly is oat milk, I chose it for my daughter because it is quite thin like breast milk and we didn't know if she'd be allergic to soya, also oats are a super food. Would imagine you could make it yourself too. Have not tried almond milk myself but think I will try it, sounds good.
I think I'm going to do it, anything is worth a go. What treatment are you guys on at the moment? I'm on ciclosporin and the p is clearing with that so don't know how well I would be able to tell if going dairy free is helpful.
Going to sound really stupid now but what's the issue with gluten? Dairy I get why it has an impact but how does gluten effect the skin, I thought it was more of a digestive thing??
And if I cut both out, keeping in mind I don't eat meat anymore, what would I eat? 
While I'm on the subject I had a friend suggest I get allergy tested by a lady she went to who practices an old chinese technique, something to do with putting the substance on your neck and lifting your leg, poss sounds a bit crazy but she gave up everything they said and it worked a treat, anyone tried that?

NCU, hi. I am not on any treatment right now; in fact the only treatment I was every on was Soriatane (acetretin?) last summer. I agree with your concern that if you are seeing success with cyclosporine it might be hard to judge if going gluten free and dairy free is effective also.
As for what going gluten free is all about, I believe gluten irritates the lining of the colon. There is a separate autoimmune disease (Celiac disease) all by its self where folks get a violent reaction if a trace amount of gluten reaches their colon lining. But it seems there are lighter variations of gluten intolerance that might only milder reactions in the colon (for example, gas) and inflamed psoriasis.
What else can you if you go on gluten free and dairy free? Well, just about everything else that is relatively anti-inflammatory. Heavy red meats are not good, nightshade veggies are not good either. Forget about junk food, alcohol and tobacco. But all other veggies/fruits are fine, rice is good, and so is fish. Several PHO forum members find juicing or blending up several fruits and veggies at once to be a convenient way to get a super dosage of nutrition all in one go; I recommend this to anyone. No doubt you might find this diet to be a bit restrictive. But in a few weeks you will see there are loads of good foods out there, your body will respond favorably to all this nutrition, and hopefully your psoriasis will fade into the distance.
Good luck!

PS - I believe cyclosporine is a drug you can only take for a maximum of 1 year because ultimately it becomes too toxic, ... at least this is the rule of thumb here in the USA. And so after a year you will be expected to transition to some other drug. Now mind you, I am not a fan of treating psoriasis with toxic medications unless absolutely necessary. Yet if cyclosporine is working for you and you are happy with it then simply carry on for the full year. During this time focus on doing an overall clean-up of your diet, keeping in mind the warning kat.chloe just gave you Once you are off cyclosporine you can do things like going diary free and gluten free.
