Yeah, you must be eating something inflammatory still, or not the right kind of oils and nutrients.
I found something on Neem oil as a treatment for psoriasis:

I think it may be worth trying too, not as THE treatment, but as an additional one. Notice that that article says it's genetic but the causes are not clear enough, and then it says that it is an inflammatory skin disorder. So, reducing inflammation must be the key. ;)

Neem oil does not cure psoriasis. Nothing cures psoriasis.
The skin disorder is a genetic condition, and we can't fix our genes (yet).
Neem can, however, be a godsend for people suffering from psoriasis, and it can help control psoriasis symptoms.
Neem treats psoriasis symptoms so successfully that some people claim to be cured. In reality they still carry the potential of a psoriasis flare up in them, but thanks to neem they can lead a symptom free life.
There is a caveat. In some people neem has indeed worked miracles, but for others it hasn't done much. Why? Well, the truth is, there is a lot about psoriasis that isn't fully understood yet, and there is also a lot about neem and neem oil that we don't know yet. As a result nobody can tell you many specifics about the interactions of neem oil and psoriasis.

Psoriasis is an inflammatory skin disorder.

The root cause of psoriasis is genetic, but carrying the genes does not necessarily mean symptoms. It also takes an environmental trigger.
Several factors can trigger or worsen psoriasis symptoms: skin infections (like boils), systemic infections (like respiratory infections, flu), stress (that's a big one), alcohol consumption (interestingly this triggers psoriasis only in males), medication.
Any skin irritations or injuries, like infections, cuts, burns, rashes, insect bites etc, make symptoms worse. Anything that weakens the immune system makes symptoms worse, and in people with autoimmune disorders (e.g. rheumatoid arthritis) or immunosuppressed people (e.g. transplant recipients, cancer sufferers undergoing chemo, HIV) psoriasis can be very severe.
Symptoms improve with lots of sunlight, air and Vitamin D. Psoriasis symptoms often clear over summer, only to return again next winter.
Neem oil is a brilliant emollient, a substance that softens and moistens dry cracked skin. This straight away eliminates a lot of the irritation and itchiness. It moisturizes and protects, and heals any lesions or scaling.
Neem also soothes the redness and irritation directly, through the steroid like effect of some of its ingredients. Yes, neem can affect your skin similar to the way steroids do, but without all the nasty side effects.
Neem oil generally enhances skin health and the natural immunity of your skin, which is one of the biggest factors in psoriasis.
Neem oil is strongly antibacterial, and the benefit of this for psoriasis is obvious. Neem cleans up any skin infections that may have developed because of cracked broken skin (due to dryness or scratching). When used regularly (by using a neem soap, neem shampoo, or neem lotion) neem also prevents any future skin infections that may aggravate or bring back psoriasis symptoms.
(As a bonus neem oil also prevents insect bites, another trigger that can worse symptoms. DEET, the synthetic chemical in insect repellents is a known skin irritant which would aggravate psoriasis symptoms.)
Neem leaf supports and stimulates the immune system. (Neem leaves are available as capsules, tablets, or as neem tea.) Anything that helps your immune system helps with psoriasis.
One research study showed that when people who used the common coal tar treatment for psoriasis also took neem leaf extract internally, then their psoriasis symptoms cleared up faster.
Other research reports showed that nimbidin, one of the components found in neem seed oil, has anti-inflammatory properties comparable to standard drugs like phenylbutazone (non-steroid) or prednisolone (a steroid).
Experiments and reports from patients with psoriasis suggest that taking neem leaf orally combined with a topical neem oil treatment (like baths, soap, lotion or salve) can be at least as effective as coal tar and cortisone in treating psoriasis, with none of the nasty side effects.
I think it may be worth trying too, not as THE treatment, but as an additional one. Notice that that article says it's genetic but the causes are not clear enough, and then it says that it is an inflammatory skin disorder. So, reducing inflammation must be the key. ;)
