According to WebMD, some of the earliest signs of balding in men and women include a gradually receding hairline and hair thinning around the crown. Men may also notice a horseshoe pattern of hair loss forming around the hairline.
According to the New York Times, male pattern baldness first shows at the hairline and forms an "M" shape. WebMD explains that hair loss all over the body is a sign that complete baldness is soon to come. Baldness may also come in atypical patterns, such as the loss of patches or clumps of hair, and may even affect the eyebrows.
