Dear Dr Rassman,
I’m confused! In this previous post (Receding Hairline Corners — Is It Just a Mature Hairline? ) you say that the person in the images now has a ‘mature’ hair line. But when he is holding his hair back I can clearly see a lot of smaller (miniaturised) looking hairs hanging down.How can this be maturing? I thought you said in another post that generally you don’t see smaller hairs like this at the leading edge of the hair line unless it is maturing?
In the transition from a juvenile hairline to a mature hairline (like mine), the leading edge often has small vellus hairs in greater quantities than further back.
In a transplanted hairline, the leading edge has very few vellus hairs that makes for a hairline with few softer hairs. In men with coarse hair, I place more single hairs in the frontal edge to try to make up for the missing vellus hairs as this could become detectable on close examination in men who have coarse hair. When I do a hair transplant on a coarse haired man, to adjust for this, I place more one-hair grafts in the frontal transition zone and break it up more that I would normally for a man that has medium or finer hair.
