How Does Finasteride Work?

Prevent Hair Loss

Finasteride (brand names Propecia or Proscar) is in the class of medications called type II 5-alpha reductase inhibitors. By blocking 5-alpha reductase, this medication blocks the conversion of testosterone to another male hormone, DHT. Decreasing the circulating DHT hormone can block its effect on hair follicles and the prostate gland. Unlike rogaine, which triggers hair regrowth, this medication prevents hair loss by blocking the conversion of testosterone to DHT. DHT can bind to hair follicles in genetically predisposed people and miniaturize them.

Furthermore, the reduction in DHT levels also contributes to the improvement of symptoms associated with an enlarged prostate, or benign prostatic hyperplasia (BPH). By lessening the hormonal influence on the prostate, it can help reduce urinary problems such as difficulty in urination and frequent nighttime urination. This dual action of promoting hair retention and alleviating prostate enlargement symptoms makes it a versatile treatment option in men’s health.
