What are the types of hair loss?
The medical term for hair loss is alopecia, and it has many different causes. The levels of hair loss can range from scattered hair loss to full scale hair loss. Some hair loss reflects a permanent and gradual change in hair growth patterns and some loss is temporary due to stressors to the body. The three major categories of hair loss are: AndroGenetic Alopecia (AGA), which is the most common type of hair loss resulting from heredity, hormones and age; Alopecia Areata (AA), which is a sudden loss of hair due to an autoimmune disease in which the immune system attacks the hair follicles, it is often reversible; Telogen Effluvium, which is temporary hair loss due to a stressor to the body, which is usually reversed once the condition is resolved.
