Hair loss can have many causes, including:
-
Hereditary hair loss: This is the most common cause of hair loss worldwide and is also known as androgenic alopecia. It affects both men and women and is caused by inherited genes that cause hair follicles to shrink and eventually stop growing hair. In men, it is called male pattern hair loss, while in women, it is called female pattern hair loss.
-
Hormonal changes: Excess androgens, or male sex hormones, and hormonal imbalances are the most common cause of hair loss, such as androgenetic alopecia.
-
Medical conditions: Medical conditions such as thyroid problems, high fever or severe infection, childbirth, major surgery, major illness, sudden blood loss, and autoimmune disorders like alopecia areata can cause hair loss.
-
Medications: Certain medications, such as those used for cancer, arthritis, depression, heart problems, and high blood pressure, can cause hair loss as a side effect.
-
Nutritional deficiencies: Deficiencies in vitamins A, B, C, D, and E, as well as iron and zinc, have been associated with hair loss.
-
Physical trauma: Physical trauma to the scalp, such as from burns, injuries, and surgeries, can cause hair loss.
-
Stress: Stress can cause hair loss, although it is usually temporary and the hair grows back once the stress is relieved.
-
Trichotillomania: Trichotillomania is a mental disorder characterized by the urge to pull out ones hair, which can lead to hair loss.
It is important to talk to a doctor if you are experiencing hair loss to determine the underlying cause and appropriate treatment options.
