Hair loss can occur as thinning hair or complete baldness. The hair loss may be on the head or any other part of the body that normally has hair, such as the eyebrows. There are many causes of hair loss. The most common form of hair loss is due to male pattern baldness, in which hair is lost from the front and top of the scalp. Other types of hair loss can create different patterns.
Treatment depends on the type and cause of baldness.
The primary symptom is hair loss. Other symptoms can vary widely depending on the cause of the hair loss. Those with male pattern baldness have no other symptoms. The location of the hair loss also differs depending on the cause. There are medications available to prevent hair loss in men with a strong family history of the common type of baldness.
