@amandaburnett up till now I have just assumed the scales and itching on my scalp was from psoriasis and now I am wondering if it is lichen planopilaris! My dermatologist has never mentioned it. I have lichen planus which seems to to be under control with Methotrexate but even with Stelara 90ml Injections my scalp is still itchy and scaly. Tried every kind of shampoo and lotions - naturopathic and allopathic but no results. I am going mental with the itching and scaling/flaking! I would like to know how to acquire that low light therapy hat in Ontario!
