What is DHT and what does it do? Testosterone, a male hormone, is converted into DHT or Dihydrotestosterone in various tissues of the body and the skin. The enzyme 5 alpha reductase converts testosterone into its more potent form DHT. DHT is responsible for causing hair loss known as Androgenetic Alopecia. DHT is thought to be approximately 10 times more potent than testosterone because of increased affinity to the androgen receptor. There is significant debate in the scientific community regarding the actual physical process of DHT and its role in hair loss. It is known, however, that it collects at the base of the hair, restricting its growth. At first, the hair will thin, then the follicle will be asphyxiated and hair loss will occur. One method of combating this asphyxiation is to stop the production of DHT by inhibiting 5-alpha-reductase. This is the method most commonly employed by products such as Propecia and Minoxidil. Procapil® does not interfere with or restrict the function of these treatments, and will only compliment their usage.
