Hair loss types
Hair loss in men is classified by the Norwood table, and ranges from Type I to Type VII. See the examples below:
Baldness Type I
Type I: minimal recession along the anterior border of the hairline.
Baldness Type II
Type II: the anterior border of the hair in the frontotemporal region has triangular areas of recession, which tend to be symmetrical.
Hair loss types, segundo a Escala de Norwood-Hamilton:
baldness Type III and baldness Type III Vertex
This type is subdivided into two parts: the first has deep frontotemporal recessions, which are usually symmetrical and are either bare or very sparsely covered by hair; the second one is called Type III Vertex, when the hair loss is chiefly in the vertex and has some frontal recession.
From the levels described above to level VII the hair loss becomes more accentuated until the last degree when hair is only found at the back and at the sides of the head.
