I am 21 years old and I think that I’m thinning. I have a prominent widow’s peak. My father (his white haired front view is shown here) and my grandfather both have balding (like the picture you showed of Dave Letterman on February 2nd, but the ‘pancake’ size area in the middle remains strong on both of them). I expect that I will keep my ‘pancake’ just like my father and my grandfather, but if I lost it, could it all be transplanted (including mywidow’s peak)? Can you tell me from my picture if I am losing my hair? I took a picture of it for you to see.
A widow’s peak can be created with a hair transplant. Many people (including me) think that it is a sexy look for people with narrow faces, and it works in a transplant when the surgeon is artistic. Some people have a widow’s peak with the hair direction pointing to the side instead of pointing front. This ‘cow lick’ in a widow’s peak is a bit more difficult to reproduce, but it can be done if the widow’s peak is eroding even with a ‘lick’. For an example of what I mean, see the photo below — click to enlarge.
The unusually good picture sent by this man (below) shows thinning behind the forelock and I took the liberty to create a zoomed version of the photo to show the difference in densities under magnification (click to enlarge).
His father’s hairline shows that the forelock is strong and I suspect the widow’s peak is a family trait (see photo below — click to enlarge).
Referring back to the son’s photo, I think that you can see this young man has reduced density and miniaturization when comparing the central part of the scalp (just behind his forelock) to the forelock. It looks like this young man will bald behind his forelock, possibly more balding than I think that his father shows now, but the strong forelock and widow’s peak may hold even if the hair around it falls out.
