Types and Causes of Alopecia
Alopecia Areata: An autoimmune condition where the hair follicle itself is attacked leaving patches of hairless skin that regrow and may shed again.
Androgenic Alopecia: This is genetic condition responsible for male pattern baldness, but can also occur in women. It results from sensitivity at the hair follicle to a hormone that causes it to thin out.
Chemicals: Harsh chemicals such as strengtheners and bleaches used to treat hair may cause it to fall out.
Deficiencies: Deficiencies of certain nutrients from the diet such as protein, iron, zinc, and biotin will inhibit the production of hair.
Fungal infections: Dermatophyte and tinea capitis (ringworm) infect the scalp and are treated with antifungal creams.
Hormonal imbalances: Hypothyroidism and hyperthyroidism as well as other hormonal imbalances can lead to alopecia.
Hypervitaminosis A: Too much vitamin A can cause alopecia.
Lupus erythematosus: An autoimmune disease in which the scalp may be attacked leading to hair loss.
Medication: Steroids or chemotherapy drugs are examples of drugs that can cause alopecia.
Secondary syphilis: Infection by the bacteria may spread to the skin and scalp causing hair loss in that region.
Traumatic Alopecia: Caused by physical trauma to the follicles such as constant plucking of the hair and injuries to the head.
Radiation: Such as that used in cancer treatment can make hair fall out by destroying the hair follicles.
Seborrheic Alopecia: Caused by dermatitis, which can be treated using medication.
Stress: Certain periods of high stress can lead to temporary hair loss.
