Finasteride 1 MG (Propecia)
An FDA approved medication developed by Merck, called Propecia (Propecia is 1 mg of Finasteride), inhibits the conversion of Testosterone (T) to Dihydrotestosterone (DHT), the hair killing male hormone. By inhibiting 5-alpha reductase from producing DHT, we can also inhibit and sometimes reverse the balding effects of DHT.
Early treatment with Finasteride can, in some patients with moderate thinning, reverse the miniaturizing effects of DHT.
Finasteride 5 MG (Proscar)
Finasteride 5 MG is FDA approved for the treatment of benign prostatic hyperplasia, or BPH. So, DHT shrinks the hair follicle and enlarges the prostate.
Dutasteride 0.5 MG (Avodart)
Another medication called Avodart, developed by GlaxoSmithKline, also inhibits the 5-alpha reductase enzymes, but in a more complete fashion than Finasteride. Avodart or Dutasteride, is also FDA approved for the treatment of prostate enlargement.
