Hair is the second fast growing tissue in the body only after bone marrow. Hair grows about 1 to 1.5 cm every month. On average, the lifespan of a human hair is 2 to 9 years.
Some common causes of hair loss:
Heredity - It is the most common cause of hair loss and occurs gradually in a predictable pattern such as male pattern or female pattern baldness, which is receding hairline and baldness spots in men and thinning hair in women respectively. Heredity also affects the age at which one begins to lose hair, the rate of hair loss and the extent of baldness.
Hormonal changes - Hormonal changes and imbalances can cause temporary hair loss. Women frequently lose more hair two to three months after delivery due to the secretion of more estrogen hormone during pregnancy. Hormone levels are also affected by the thyroid gland, so thyroid problems may cause it.
Scalp infections - An unhealthy scalp can cause inflammation, resulting in hair fall. Skin conditions that lead to hair loss include seborrheic dermatitis (dandruff), psoriasis, and fungal infections such as ringworm. Once infections are treated, hair generally grows back.
Alopecia areata - Alopecia areata is an autoimmune disorder in which the immune system attacks hair follicles. It occurs equally in men and women. The cause is unknown, but it may be triggered by stress or illness.
Iron deficiency anemia - This is one of important causes especially in those who don't eat iron rich food. Since red blood cells transport oxygen to cells throughout body, hair follicles are deprived of oxygen in people having anemia.
Lack of protein - If a person isn't get enough protein in diet, the body may ration protein by shutting down hair growth. So one shouldn't neglect the adequate intake of this essential macronutrient.
Sudden weight loss - Sudden weight loss is a form of physical trauma that can result in thinning hair. Loss of hair along with noticeable weight loss may also be a sign of an eating disorder such as anorexia or bulimia.
Medications - Hair loss can be caused by drugs used for cancer, arthritis, depression, heart problems, high blood pressure and birth control. Intake of too much vitamin A may cause it as well. Chemotherapy destroys rapidly dividing cancer cells but simultaneously it may also destroy rapidly dividing cells like hair.
