Comment on What to Do When Hair Feels Greasy After Washing? by AnnieO.

I was having the same problem, it started with a patch of hair on the crown of my head, and was spreading forward. I was so disgusted! What worked for me was OGX Extra Strength teatree mint shampoo. I bought it at Walgreens. If it didn’t work I would have tried an apple cider vinegar rinse, but I REALLY hate the smell of vinegar. If the shampoo stops working, I will be sure to update on here. Also, I have psoriasis, which I am positive created this scalp problem. Different causes for it may have different solutions?
