Persistent frontal hairline

I have published on the genetics of the persistent frontal hairline. This man could bald and yet keep his frontal hairline.  For a hair transplant surgeon, that means that he will not have to get the leading edge of his hair transplant, saving the patient money and donor grafts.  For him, it means that he will retain a frame to his face with a good comb-back of his hair for styling purposes.
