In most cases, male hair loss is caused by hereditary Androgenetic Alopecia, more commonly known as “male pattern baldness”. The tendency for male pattern baldness is genetically inherited from either side of the family and begins to develop after puberty. The presence of the hormone Dihydrotestosterone (DHT), in a genetically susceptible man, is necessary for male pattern baldness to occur. There is no cure. Good nutrition can positively affect the quality, but not quantity, of hair.
