Advice on Thyroid, DUPA, Bald Spots please

[HelloVera]

After been a Lurker for a few months and since my hairloss is getting a lot worse thought i'd see if anybody had any advice since the situation is getting worse.

I started losing my hair when i was about 31, mostly in a diffuse pattern and slow frontal/temple pattern. Went to see a doctor and she said i have either premature balding/ scalp psoriasis, got given keto shampoo and quick blood tests told i was ok. Its been getting worse since. Anyway last year had family tragedy. My hairloss worsened and i ended up with depression. April this year decided to go to the doctors. This time the doctor took me serious because worst symptoms and gave me blood tests. Got an emergency call saying i had extremely bad hypotyhroidism, turns out its been like that for good 2/3 years. Got put on 50mg lexo for 3 months, got told to up the dose to 100mg last week.

My hair seems critical now with DUPA and bald spots appearing all over my scalp esp at the back, does seem red n imflammed as well but not much itchy. Is this common in Hypo and reversible? One Doctor didn't check my scalp and when i asked for a biopsy the other told me to wait till the lexo kicks in but its got worse in the last 3 months.
