8/16/2023 0 Comments Spike hair menScientists haven’t agreed on a theory for whether there is an evolutionary reason for age-related hair changes in men, says Dr Steven Daveluy, an associate professor of dermatology at Wayne State University in Detroit. It could be because of different hormones or other aspects of ageing, Anawalt says. The reason your eyebrows become bushier or thinner over the years is not entirely clear. In this case, testosterone inhibits hair growth in follicles on the head, causing scalp hairs to fall out and be replaced with short, fine, barely perceptible hairs.Īnother curiosity: Testosterone seems to have no effect on eyebrow length. Paradoxically, testosterone can have the opposite effect on the scalp if you’re genetically predisposed to baldness. In other words, if you come from a long line of men who grow full beards or long nose hairs, there’s a good chance you or your son will inherit this feature as well. “There are genetic differences in responsiveness to testosterone in those areas, which is why some people get a thick, luxurious beard and some people don’t,” Anawalt explains. These new, errant hairs “reflect the slow effects of testosterone over a lifetime on those little hair bulbs in those areas”, Anawalt says. During puberty, for instance, androgens (sex hormones that are more abundant in men than in women) such as testosterone trigger hair follicles on the face, chest, underarms and pubic area to replace existing short, light hairs with thicker, darker hairs that grow for longer periods of time.Īs men age, typically as they enter their 40s, 50s and 60s, testosterone’s effect on hair growth may start to become apparent in new, sometimes perplexing, ways. Hormones come into the picture by influencing when and where hair grows on the body, what type it is and how long it grows. If it bothers you, there are plenty of ways to nip it in the bud. Still, that doesn’t mean you have to live with it. But why does it happen? The short answer is that hair growth later in life has a lot to do with testosterone and genetics. However it begins, rest assured that this is a normal part of ageing for many men. Or perhaps your barber asks if you would like the mini thicket of hair sprouting from your ear lobe trimmed along with your sideburns. Maybe you spot a few long hairs dangling from your nostrils. Is this normal? Why does it happen? How can I get rid of it? Q: I’m a man in my 50s and have noticed hair sprouting in weird places like the tops and insides of my ears and in my nose.
