It doesn't: Topical Dht blockers are no effective. Oral fin asteroids blocks Dht from the inside and does work on most men especially on the middle of the scalp.

Not exactly.: Dht blockers (such as finasteride) will slow down or even reverse balding in men, but localized hair loss (alopecia areata) is not affected by Dht blockers. You'll need local steroid injections for that, from a dermatologist.
