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.
