Anyone Else Balding?

I realise this sounds kind of silly out of context. Have been having hair loss for a couple years, thinning, falling out, etc. Been having mixed results with rosemary oil. Not too keen on trying minoxidil. Very young and wondering if this happened to anyone else. I am specifically on a very poor diet ATM, but vitamins are normal—except for low B12. I read famotidine was a potential cause, although I don't use famotidine. Not looking for a diagnosis; just curious how many other people this affects, if any. First post here, so please let me know if I missed any important post guidelines. Thank you!
