Hair loss is caused by a variety of factors: hereditary (trichodystrophy, androgenic alopecia), concomitant medical conditions, hormonal disorders (thyroid gland disorders, insulin resistance), autoimmune (patchy alopecia, systemic lupus erythematosus), nutritional disorders, environmental factors (medicines, UV radiation), psychological factors (stress, trichotillomania), and ageing.
