Regrow Hair Lost from Triangular Alopecia?

Hello,
I believe i have since my 20s (now 38) triangular alopecia – a small bald spot on one side of my head (above the ear). Thinning on top since early 20s. Been on minox 5% and finasteride for 1 yr. No change in bald spot apart from lots of vellus hair. Will it ever grow or is a transplant into that area the only solution. Many thanks

I would doubt that it would regrow from minoxidil. Hair transplants work well. See this previous post for more on triangular alopecia.
