A person’s health is reflected in their hair. The causes of hair loss are related to genetics, hormones, nutrition, stress, diseases, and other factors.
1. Androgenic Alopecia
According to Dr. Zhang Shiheng, the director of Neihu Qiluo Integrative Medicine Clinic, androgenic alopecia (pattern baldness) is the most common cause of hair loss and is related to heredity. Androgenic hormones are metabolized by the body’s 5α-reductase enzyme into dihydrotestosterone, which attacks the hair follicles and causes hair loss. Once dihydrotestosterone is produced in the body, the hair follicles will shrink and degenerate, and hair loss will begin.
