A typical female hairline is rounded and the leading edge should have a no-hairline hairline. This means that the transition zone should be built between your forehead and your thicker hairline so that there is no beginning of the hairline that looks like a ‘line’. Your picture on the left should be compared with a hair transplanted no-hairline hairline on the right below. Note the rounded soft nature of the hairline on the right which was completely transplanted, including the temple peaks and an advancement of the middle hairline about one inch, while the photo on the left is straight enough to draw a line connecting the hairs. I would build a transition zone with hair transplants to soften the abrupt hairline that is shown.
