Norwood-Hamilton Scale

COMPLIMENTARY CONSULTATION

When considering treatment for your hair loss, it is important to understand just how far your hair loss has progressed. There will be times when you will have to relay this information via telephone or the internet to physicians or practitioners you may be trying to receive information from.

Norwood Hamilton Scale

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

Class II indicates a progression to the adult or mature hairline which sits a finger breath (1.5cm) 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.

Class A patterns are less common than the regular pattern (<10%), but are significant because of the fact that, since the hair loss is most dramatic in the front, the patients look very bald even when the hair loss is minimal.
