As a rule, does miniaturization need to be present behind the frontal hair line to indicate genetic hair loss? What would you say to someone who presented you with an intact, albeit mature, hair line – with no thinning present behind but had noticeable vellus hairs along frontal edge particularly in the corners where the hair line had raised a little bit with age? These “straggler” vellus hairs look to be the remnants of a retreating hair line – from juvenile to mature – but its hard to tell and self-diagnosis is uncertain at best.

On occasion, I have seen some men lose hair without going through miniaturization. This is more common in the process of developing a mature hairline, but anything is possible. At times, some vellus hairs remain in the frontal area where the juvenile hairline formerly was.
