I believe you can't read my statement, "with the use of minoxidil you "may" be able to savage some". There is no guarantee this could happen. OP's question is if he can regrow his hair on his temples not if he can maintain his hair.
"The effects of
finasteride are confined to areas of the scalp that are thinning, but where there is still some
hair present. It
does not
grow hair in areas that are completely bald. Although it
can regrow hair in thin areas, the major benefit of
finasteride seems to be in its ability to slow down or halt
hairloss.". -

I've seen numerous dermatologists and they said the exact same thing with these statements.
"Rogaine for example has a 30% chance of slowing progression of hair loss, but only 15% chance of leading to hair regrowth. The regrowth will be noticeable on areas where there is thin or weak hair. Do not expect regrowth on skin bald areas. It just doesn't work that way."
Hence the 'near impossible'. Sure there are stories but they're rare.
