Beard Growth And Testosterone
The Undeniable Link Between Testosterone And Beard Growth
The reasons behind the evolution of male body hair are often debated – some say it developed to protect man from the sun during the hunting phase, while others say it provided camouflage for stalking prey. Whatever the reason for it, one thing is clear – the beard is the ultimate symbol of masculinity.
And what sits at the core of all things masculine? That’s right: testosterone. But does the ability to quickly grow facial hair necessarily indicate high T levels?
Let’s get to the basics on T.
Testosterone is an androgenic steroid hormone that’s created naturally in the testes. It plays a crucial role in male development and is regulated by the gonadotropin-releasing hormone (GnRH), which sends signals between the brain and the testes. The more of these there are, the more T is created.
Testosterone provides all kinds of manly characteristics, with two different types of effects:
- Anabolic effects –the development of male characteristics like strength, voice deepening and hair growth
- Androgenic effects– protein metabolism and inhibition of protein breakdown, triggering lean muscle levels and low body fat
These hit a peak during the puberty, where the body is hit by its first major increase in androgen levels. This leads to a range of developments including:
- Voice deepening and Adam’s apple development
- Penis and testes growth
- Muscle growth and higher bone density
- Growth spurts
- Hair growth
After the age of 30, however, GnRH struggles to stimulate the Leydig cells as well, disrupting T levels and inducing muscle loss, hair loss and weight gain.
But What About The Beard?
There’s no denying that facial hair and masculinity and inextricably linked.
Studies claim that beards are perceived to symbolise:
- That you have health and fitness
- That a man is aggressive and ready for battle
- That you’re sexually mature
The first inklings of a beard usually appear during puberty, but not all men have the same ability to grow a beard. While some men simply palm this off as genetics, this actually comes down to the hormones testosterone and dihydrotestosterone.
But What Is Dihydrotestosterone?
This is also known as DHT, a metabolite of testosterone. While a more powerful androgen than Testosterone, it can’t be produced without testosterone being available first. That’s because testosterone is a prohormone that nudges DHT production, all with the help of the catalyst enzyme 5-alpha reductase (5-AR). So if you have high T levels, you’re also likely to have high DHT levels. And one of the many characteristics these two hormones are responsible for, one is beard growth.
And the link between beards and testosterone is clear in other ways, too.
An American Psychological Association study revealed that a group of women judging the attractive of men based on whether they were fully bearded, moustached, goateed or clean-shaven, the bearded men won out. Some of these reasons offered by the participants included that the man seemed more:
- Self confident
The Link Between Testosterone, DHT And Beard Growth
The underarms, genitals, legs, arms chest and face are all particularly sensitive to androgens. The androgens testosterone and DHT play two distinct roles in the development of male facial hair:
- Testosterone – primes the hair follicles for growth
- DHT – directly promotes linear growth.
This makes facial hair distinct to that on the scalp – it has flatter follicles so is therefore curlier and coarser than scalp hair.
Those with low testosterone have low androgens, and will therefore lose body hair.
