Reasons for Hair Loss in Girls

Alopecia is the term used for partial or complete hair loss. Female hair loss is most commonly caused by hormones such as testosterone, genetics, autoimmune conditions and aging. The loss typically occurs slowly over time and can be diffused throughout the scalp or it can follow male pattern baldness. In most cases, it can be treated once the cause has been identified.

Lupus

• Lupus is an autoimmune disease. It is chronic, meaning that its symptoms last for more than a month and a half, and it can also affect any part of the body. Lupus cannot be caught from another person, or given to someone else, and it is not genetic. However, those who have certain family members with lupus are at a higher risk of developing the disease. Lupus occurs more often in females of childbearing age. It is an active disease, and can disrupt the plugging of hair follicles, leading to clumps of hair falling out.

Syphilis

• Syphilis is a disease caused by the bacterium Treponema pallidum. It is sexually transmitted, and is known as the great imitator because it mimics many other diseases. Syphilis can go undetected for years, and hair loss, along with weight loss, muscle fatigue, headaches, sore throat, swollen lymph nodes and fatigue may occur in the secondary stage. Syphilis can be found through blood tests.

Thyroid Disease

• The thyroid is a small gland that is shaped like a butterfly and located above the collar bone. Thyroid disease can cause fatigue, heat sensitivity, hair loss and metabolic problems. Thyroid disease affects millions of Americans, and is more common in women than men. The overproduction or underproduction of hormones caused by thyroid disease can affect the hair follicles and lead to hair loss.

Polycystic Ovarian Syndrome

• Polycystic Ovarian Syndrome is a health problem that is characterized by the small fluid filled sacs that appear on the ovaries. PCOS causes a woman to have high levels of male hormones called androgens. It can affect the menstrual cycle, heart, blood vessels and a woman's ability to become pregnant. It can also alter a woman's appearance by causing male pattern hair growth, acne, oily skin, dandruff, and hair loss. Hair loss is due to prolonged exposure of the hair follicles to testosterone.

Childbirth

• Telogen effluvium is the term used to describe the loss of hair that occurs after pregnancy. During pregnancy, the increase in hormones causes the hair to go into a state of rest, therefore keeping it from falling out. Once the child is born, and the hormones begin to regulate, the hair will return to its normal cycle.The hair that was kept from falling out during pregnancy will shed, and new growth will appear within six months following the birth.
