DHT is the abbreviation for the word Dihydrotestosterone, and end product when contact is made between the enzyme 5-alpha-reductaste in the scalp, and the testosterone hormone.

DHT causes hair loss because it binds to receptor sites on the scalp and the hair follicles. This interrupts the process necessary for continual healthy hair growth when it sends false signals to the cells functioning for the hair’s proper growth. The reason why men usually lose hair in the temporal, crown and vertex depends on the location of most DHT in the area. The concentration of sweat carries the DHT to those areas, and thus, concentrating the hair loss as well.
