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.
