I'm shedding regrowth and have scalp discoloration. Possible AGA?

I shed 90% of my hair last Mar to Aug. I had severe scalp pain and itching too. Some derms said it was early AGA from both my parents. But when I shaved my head in Aug I had discolored spots in the areas of pain. My hair thickened after Aug and starting Spiro and Fin. But this past month I've been shedding tons again. Itch and soreness are worse, and those areas are thinner. Is this inflammatory/scarring? Is it AGA? Is it a Fin or Spiro shed? I'm waiting for biopsy results. Thanks.
