Does the Hairline Mature When the Beard Grows?

Hey Dr. Rassman,
I have a question about the maturing hairline. Is there any sort of sequence to overall hair growth/development; specifically, does the hairline tend to mature before/after/simultaneously with the growth of the beard or other body hair? If I already have a full beard, is it reasonable to assume I’ve already got my mature hairline, or does the hairline mature independently of other body hair maturation?

I have described the mature hairline here and here, however, I do not believe anyone really knows (including me) the exact order or timeframe in which a maturing hairline develops. Medicine is a descriptive science at times, and sometimes all I can do is describe what I have seen and observed.

Experience shows that the hairline takes on a receding leading edge sometime between the ages of 19-29 on average. Body hair usually comes on later than pubic and underarm hair. This is a DHT mediated series of events, however there is much more than DHT behind these changes. So no, hairline maturation is not linked to the growth of body hair. If you are concerned, you can see your primary doctor or a dermatologist.
