At our Los Angeles Hair Restoration clinic, we see many different patterns of male baldness. One of the most widely known is the photo above. The Norwood Class A pattern has been around since the '70s and is characterized by front to back hair loss.

Class I

represents an adolescent or juvenile hairline and is not actually balding. The adolescent hairline generally rests on the upper brow crease.

Class II

indicates a progression to the adult or mature hairline that sits a finger's breath (1.5 cm) above the upper brow crease, with some temporal recession. This also does not represent balding.

Class III?

is the earliest stage of male hair loss. It is characterized by a deepening temporal recession.

Class III Vertex?

represents early hair loss in the crown (vertex).

Class IV

is characterized by further frontal hair loss and enlargement of vertex, but there is still a solid band of hair across top separating front and vertex.

Class V

the bald areas in the front and crown continue to enlarge and the bridge of hair separating the two areas begins to break down.

Class VI

occurs when the connecting bridge of hair disappears leaving a single large bald area on the front and top of the scalp. The hair on the sides of the scalp remains relatively high.

Class VII

patients have extensive hair loss with only a wreath of hair remaining in the back and sides of the scalp.
