If I have a hair transplant, I want to know if you can put back the Widow’s Peak that I had as a kid?
Yes. See the photos of Extreme Makeover patient Marque below. The photo to the lower right shows a frontal hairline restoration with a widow’s peak, just as you asked. The photo at the left is before 2 procedures totaling 3455 grafts. When I create a widow’s peak, I generally do not like to make it ‘regular & tight’ and prefer to have some patchy elements to it, for it makes it look non-man made. Please click to enlarge.
