Do DHT blockers reduce body hair?
It has been reported that both Dutasteride (Avodart) and Finasteride (Propecia) can reduce chest hair. One doctor did report that he counted body hairs and found the count dropped by half on one patient he followed. The patient, of interest, did not notice the reduction.
Based upon this, one might expect that it will also reduce nose hair and ear hair, or at least the build up of these unwanted hairs. If I knew for certain that there was a solution that was as simple as a pill, I might offer it to all of my patients and I would even take it myself. The story, however, is still out.
