Using oral Minoxidil .25mg, 14 weeks in, 26 yr old male, also on Finasteride daily, previously on Minoxidil topical 7%

My question is, i was prescribed .25mg oral minoxidil for hair loss i was told it is more effective than topical 7% (dermetologist told me this) after 14 weeks i have lost over half my frontal area, my temples which i gained r now gone and there are no signs of things getting better, my concern is i have only seen tests done on women for .25mg, is .25mg really effective for Men, or is it equivelant to 2% topical, i am very concerned, i was better off before, granted its only been bit over 3mnths
