Query: Tea tree oil therapy - not for me

I have oily hair and a scalp that gets itchy a day after washing. I thought itchy scalp was just something I had to live with until I tried a shampoo from Pytho that actually controlled the itching. Unfortunately that shampoo was discontinued. From then on I had went on a search for a shampoo that can tackle my itchy scalp.I tried Garnier Dandraff shampoo, Neutrogena T-Gel, Jason scalp therapy, and even some African black shampoo. None could control the itch in any reasonable degree. Neutrogena seem to perform better, while Jason performed worse than regular shampoo. Maybe the Jason shampoo was meant for dry hair?Finally tried this one called "Head & Shoulders Clinical Strength Anti Dandruff Shampoo" and finally I'm back to having no itchy scalp.Of course, different shampoo works for different folks. My only advice is to try the cheaper shampoo first before moving up to ones that cost 15 or 30 dollars a bottle.
