The following describes some of the many other  causes  of  hair loss: 

Hair Disorders: Hereditary thinning or baldness (also called androgenetic alopecia): This is the most common cause of hair loss. It affects men and women.

Disease: Underlying medical condition: Hair loss can be the first sign of a disease. About 30 diseases, including thyroid disease and anemia, cause hair loss. By treating the disease, hair loss often can be stopped or reversed. 

Illness: Significant hair loss can occur after an illness. A major surgery, high fever, severe infection, or even the flu can cause hair loss. Your dermatologist may call this type of hair loss telogen (tee-lə-jen) effluvium (ih-flu-vee-uhm).

Ringworm of the Scalp: This disease is contagious and common in children. Without effective treatment, ringworm can cause balding. 

Hormones and Stress

Giving birth: After giving birth, some women have noticeable hair loss. 

Falling estrogen levels cause this type of hair loss. The hair loss is temporary. In a few months, women see their hair regrow.

Menopause: Hair loss is common during menopause. This loss is often temporary. Hair regrows with time. If a woman is 40 years of age or older, she should not expect her hair to have the fullness that it did when she was younger. 

Stress: Experiencing a traumatic event (e.g., death of a loved one or divorce) can cause hair loss. 

Dieting and Poor Nutrition 

Weight loss: Some people see hair loss after losing more than 15 pounds. The hair loss often appears 3 to 6 months after losing the weight. This hair loss is common. The hair re-grows without help.
