Causes / Reasons / Risk Factors of Hair Loss:

There are different factors may influence hair loss,

• Genetics: Almost all pattern hair loss is caused by heredity, from genes passed on by both maternal and paternal ancestors.
• Hormones, such as abnormal levels of androgens (male hormones normally produced by both men and women)
• Autoimmune disorders may cause patchy hair loss in children and young adults.
• Diseases: Thyroid disease, lupus, diabetes, Iron deficiency, eating disorders and anemia can cause hair loss.
• Nutritional deficiencies: Low protein diet or severely calorie-restricted diet can also cause temporary hair loss.
• Poisons
• Drugs including chemotherapy drugs used in Cancer treatment, Beta adrenergic blockers used to control blood pressure, and birth control pills can cause temporary hair loss.
• Radiation exposure: Ionizing radiation such as the type used for cancer treatment, also affects rapidly dividing cells most severely, and, as a result of exposure to radiation, actively producing hair follicles are shut down.
• Stress, illness and childbirth can cause temporary hair loss.

• Physical trauma to the scalp such as from wounds from accidental cutting or impact, thermal burns from heat or fire, chemical burns from acids, alkalies, or other caustic substances.
• Hair styling technique: This type of hair loss called traction alopecia can result from certain hair-styling techniques that pull tightly on the hairs, such as tight “cornrow” braids and pigtails. Modifying these styling techniques so that they are not too tight solves the problem.
• Cosmetic products and procedures that weaken or damage the hair shaft can result in hair loss.
• Common causes: There have been numerous causes blamed for pattern hair loss, including “hot blood,” excessive blood circulation in the scalp, inadequate blood circulation in the scalp, wearing hats, brushing the hair too much, brushing too little, dirty scalps, oily scalps, hormones in scalp oil, dandruff, various diseases, excessively tight scalps, inadequate oxygen reaching the hair follicles, inadequate nutrition or nutritional deficiencies, “sleeping” hair follicles, and hairs “stuck” in the hair follicles.
