Class 2 & 2A

The first "Classes" of hair loss represented at left. Most men will become affected by either stage in their lifetime. In the top image, the hair line starts to recede and a "widow's peak" above the temples is evident. In the second image, the hairline starts to recede farther back from the front and begins to "catch up" with the widow's peak. Not evident in this picture, but to some of our clients, is that the hair on the back of the head is becoming thinner as the hair follicles become weaker and fall out.

Class 3, 3A, 3V

In Norwood Class 3 (includes 3 Anterior, 3 Vertex) of this chart, men notice a more significant decline in hair above the temples as well as receding from the forehead. Hair loss is also starting to become signicant on the crown or vertex (bottom image). See our Before/After Hair Transplant Gallery to see an HTC patient with similar hair loss who was treated.

Class 4 & 4A

In class 4 and 4A (anterior), hair loss may become more noticeable on the crown,  or patients may have only significant loss from above the temples and and frontal anterior area (bottom photo). See our Before/After Hair Transplant Gallery to see an HTC patient with similar hair loss who was treated.

By Class 5, 5A (anterior, middle) and 5V (vertex, bottom), hair loss is approaching significant levels, with most of it disappearing on the top of the vertex and crown.  By these stages, more hair grafts will be needed to provide both coverage and density. See our Before/After Hair Transplant Gallery to see an HTC patient with similar hair loss who was treated.

Class 6 & 7

Class 6, top, hair loss is major but there still is donor area
available to use for hair transplants. See our Before/After Hair Transplant Gallery to see an HTC patient with similar hair loss who was treated.

By the final and worst stage of hair loss, (and not all men reach this stage), hair loss is severe and a suitable donor area is almost nil.
