The most common form of hair loss is androgenetic alopecia, more commonly known as male or female pattern baldness. This type of hair loss is hereditary and is caused by the hormone dihydrotestosterone (DHT).
DHT is short for the hormone/androgen dihydrotestosterone. DHT is formed when the 5a reductase enzyme synthesizes DHT in the body’s adrenal glands and hair follicles. It is also important to understand that changes in the metabolic function as well as the production of various androgens such as DHT can have a drastic impact on hair loss in both men and women. A larger number of men in the world will be affected by this type of hair loss. By the age of 80, almost 80% of the world’s male population will have experienced some level of hair loss from androgenetic alopecia. But almost 40% of the world’s female population will also experience hair loss from the hormone DHT.
