Finasteride and facial hair

I have read of some people seeing no impact on their beard development whatsoever from taking finasteride whilst other peoples beards have completely halted growth of new hair. I understand the impact finasteride has on ones beard is different in every case but will topical finasteride have the same impact as oral? Thanks

No, as a good topical liposomal finasteride will stay in the scalp and will largely not go systemic. A patient of mine last week told me he checked his DHT level on topical liposomal finasteride and there was no change in the DHT level he measured before going on this topical drug
