The
Hamilton scale is widely used by the professionals to
classify the degree
of baldness of the patient.
The typical pattern of hair loss is divided into seven
categories.
No hair loss is termed ‘type I’.
Minor recession of the frontal hairline is termed ‘type
II’.
Type III indicates further frontal loss, and is considered
‘cosmetically significant’.
The subset of type III, termed ‘III vertex’,
shows significant frontal recession coupled with hair
loss
from the vertex region of the scalp. Types IV–VI
show further frontal and vertex loss, culminating in type
VII, in which only the occipital
scalp region maintains significant amounts of hair.
