I would consult with a third physician, ideally a highly regarded dermatologist specialised in thricology, if you want to hear a highly experienced opinion.
Check out the Spanish group of dermatologist in Madrid led by Dr. Serjo Vaño, some of them as Dr. Muñoz also offer online consultations. I am a last year Italian medical student doing my thesis in dermatology regarding alopecia areata and I can guarantee you that, at least at the moment, they are at the forefront of hair research in Europe and globally. I am advising to consult specifically with one of them because they were the doctors that introduced low dose oral minoxidil in the hairloss niche back in 2017, so they have more experience more than anyone else.
Hope it can help
