I had this problem a few months ago and I watched a Youtube tutorial for getting rid of itchy scalp and dandruff at home. I can't remember exactly which one I watched, but after doing what it said my head felt amazing...so much relief! I think it was doing a scrub first with baking soda and olive or coconut oil. Then you let it sit a bit. Then you rinse in the shower with apple cider vinegar. Then you can shampoo like normal. It felt really good and no itchy dandruff has come back since then.
