In my experience, performing hair transplants on firefighters, police officers, and soldiers can be a problem, not because they are different from you and I, but simply because they tend to get more good-natured teasing from their colleagues when issues of vanity come up. Although I haven’t seen any formal studies about it, I’ve found that society looks at the man in uniform as a “macho” guy, and vanity + macho don’t exactly go hand-in-hand. This is why I’ve found that these men can be more sensitive than the average male about having a hair transplant, as they are extremely worried about having a detectable procedure.
This patient had two hair transplant procedures totaling 2431 grafts to the frontal hairline, extending back about 1 1/2 inches. His skin is light and his hair is jet black, but he told me that no one ever teased him about undergoing the surgeries and nobody noticed anything unusual.
The photo on the left is before; the photo on the right is after two procedures. Please forgive me for the quality of the before photo, as it was taken with a different camera under different lighting, but his hair loss is clearly evident. Click the photos to enlarge.
