I have bought some tea tree oil to add to my shampoo and conditioner in the hope that it will help my psoriasis.
I'm not sure how much to add though, the web suggests anything from a few drops to fifteen, but no mention is ever made about how big the bottle of shampoo is!
The assistant in Holland & Barrett was little use, she advised against me trying it as it would dry my scalp out and then went on to try and sell me Tea Tree Shampoo & Conditioner!
I have always used the essential oils as a final rinse. A small water bottle, about 500ml, with warm water and about 5-10 drops of the oil into it, shake well and use. Did this with lavender and tea tree as a deterrent for the deadly hair lice, when my grand-daughter was being plagued by them at junior school.
Might be better using rosemary and lavender oil together tea tree can be quite fierce
one drop of each in the amount of shampoo you'd use to shampoo your hair
don't put it into the bottle in bulk do each one fresh as the oils 'go off quickly'
another thing to try might be strong nettle tea make up a cupful allow to go cool pour it on and work it into roots of hair and leave for 15 mins then rinse really well
I've suffered with psoriasis for many years but fortunately I didn't have it on my scalp but my daughter did, the only thing that worked for her was a prescription ointment from her dermatologist. My Mum used cheap Coconut shampoo and conditioner for her scalp psoraisis and this worked for quite a long time but then stopped being effective, she now uses pure Shea butter, I think this softens the flaky patches and makes them easy to come off and for now seems to be working. I've never heard of using Tea Tree Oil, but I would start with a few drops and see how effective it is and then add more.

get a little dish and mix it in that or make up small quantities in a small glass bottle enough to do three or four washes. The nettle tea is slightly astringent but works on other flaky sore scalp conditions,, the rosemary and lavender are supposed to have slightly anti inflammatory properties as well
ive tried most things over the years , the most effective i have recently tried is polytar which i got of e bay, not 100% but does seem to make a difference.
