How come topical finasteride even works at all?
    Finasteride/Dutasteride 11/9/2025

    At a glance
    In this question or advice post, the primary subjects mentioned are
    💧 Finasteride (topical) 0.1% everyday
    💊 Dutasteride (oral) 0.5mg 3 times a week
    💊 Finasteride (oral) 1.25mg 4 times a week
    💧 Minoxidil (topical) everyday
    the tone is 😐 neutral.
    Topical finasteride can effectively reduce scalp DHT by targeting local enzymes, despite less systemic impact compared to oral forms. Combining oral dutasteride with topical finasteride and minoxidil may enhance hair loss prevention, though evidence of its effectiveness is limited.
