Staging alopecia into both pattern and degree of severity can be accomplished through the Hamilton classification. Patients with Hamilton patterns I and II have very early limited alopecia requiring minimal treatment if accepted as candidates. Conversely, patients with patterns VI and VII may no longer be candidates for the surgery since their alopecia is so extensive. The very best candidates fall into patterns IV to V, which produce the best, most natural results. See the image below.
