I am rapidly getting lot of white nd silvery hair long nd short new ones  especially on  a particular side  of my head and it is increasing rapidly which doesn't seem to be genetic  .Iam also suffering increased hair losss despite on finasteride(5 mg 3-4 month) nd minoxidil + for years) which taking due to androgenetic hair loss fr years as hv normal androgen sensitivity due to my dad.But lately I feel hair loss due to hormonal improved but that same white hair area had  more haie loss so that is taking time  .I M feeling I m having alopecia aerata too as not easily recognised due to my overall thin head .   suggest me tests general nd immune I need to have .can't go outside due to corona to show doctor .Or if somecan is confident they can help me properly diagnose I m ready fr online consultation too but I think in video it will not be clear
