Baldness is often thought as a sign of old age, unattractiveness, and infertility in men. Although none of these may be true, this can be a cause of low self-esteem and low self-confidence. Permanent hair loss comes from hair follicles that become thinner and weaker. Male patterned baldness is scientifically called Androgenetic Alopecia, and is caused by genes
[basic, functional units of heredity, each occupying a specific place on a chromosome.] , hormones
[chemical substances created by the body that control numerous body functions.] , and age.
