Causes & Treatment of Leg & Arm Hair Loss in Men

Updated July 19, 2017

Hair loss is a troubling thing for men. It is typically relegated to the head, often in the form of male pattern baldness, though some conditions can cause hair loss over other parts of the body, including the arms and legs.


The main cause of hair loss of the legs and arms in men is alopecia areata, according to the American Hair Loss Association. It typically occurs in conjunction with hair loss over most of the body and is thus referred to as alopecia universalis.


Alopecia areata develops when the immune system, for no discernible reason, attacks the body's own hair follicles. This makes the condition an autoimmune disease, according to the Mayo Clinic.


Alopecia areata in all its forms typically begins as patchy hair loss, according to the Mayo Clinic. It is often accompanies itching and an overall soreness of the affected area.


The most common form of treatment is corticosteroids, according to the American Hair Loss Association. Other possible treatments include chemicals applied to the skin that can help stimulate hair growth.


There is no one singular effective treatment for alopecia universalis and every possible treatment available can have varying effects on each person.
