Does the Beard Get Thicker with Age?

Does the Beard Get Thicker with Age

My uncle who is 30 years of age has been able to grow a full beard. I got curious whether when I reach 30 years my beard will fill in. I did some digging here is what I found.

So, does the beard get thicker with age? Yes, facial hair will get thicker and fuller with age, as you age your androgen receptors (genes) become more sensitive to both beards growing hormones (testosterone and dihydrotestosterone) increasing the growth and thickness of your beard. However, not everyone will experience beard thickness with age factors such as one’s ethnicity, testosterone, or health conditions hamper beard growth.   

Read on to discover why your beard becomes thicker with age.

Beard thickness and Age

What stimulates beard growth?

The growth of the beard is affected by two factors your testosterone and genes. The extent of beard growth is controlled by the sensitivity of your genes (androgen receptors).

The production of testosterone hits its pick when you hit puberty. It is converted to a more potent hormone called dihydrotestosterone.

Testosterone primes the hair follicles and dihydrotestosterone promotes linear growth of your facial hair.

Why can some young men/teenagers grow a thicker beard while others cannot?

Genes/Androgen receptors sensitivity

As stated earlier, beard growth is affected by genes and testosterone.

The reason some men can grow a fuller beard when young is based on the sensitivity of their androgen receptors.

The more sensitive the androgen receptors are to testosterone and dihydrotestosterone the thicker a beard grows. 

Hair follicles

Some men have hair follicles that grow very thick facial hair. So in real sense, a man may not have so many hair follicles but the hair that comes out of their facial hair follicles will appear thicker than it really is.

What causes the beard to get thicker with age?

Proper production of testosterone

Mostly, men have the same levels of testosterone levels. But there are a few who do not have the required amount of testosterone. When you hit puberty, testosterone production increases as it is also used in the formation of your secondary characteristics.

While the extent of beard growth is solely on your genes, low levels of testosterone will also hinder your beard from attaining its maximum potential.

The life that you lead may greatly affect your levels of testosterone.

A lifestyle that does not involve getting enough sleep, too much stress, alcohol poor diet will lead to decreased testosterone levels that will affect your beard growth.

With age comes increased genes sensitivity

There are two types of men when it comes to growing a beard, early bloomers and late bloomers.

 For early bloomers, they can grow a beard pretty early as compared to late bloomers.

A late bloomer may grow a beard but it will be patchy, as they age their genes becomes more sensitive to the beard-growing hormones hence they patchy beard will start filling in and becoming thicker.

A late bloomer may also have had some inactive facial follicles which become activated with age and hence help them grow a thicker and fuller beard.

What can you do to make sure you give your beard a chance to grow thicker and fuller with age?

Increase testosterone levels

The first step is to make sure that your levels of testosterone are at par. Low testosterone will only derail the growth of your beard. 

There are several ways to increase your levels of testosterone.

  • Exercising
  • Get enough sleep
  • Avoid stress
  • Alfalfa sprout
  • Ashwagandha
  • Creatine

Increase the level of sensitivity of your genes

The sensitivity of your genes will determine the extent to which your beard grows.

There are several ways to increase the sensitivity of your androgen receptors to dihydrotestosterone.

Sensitive androgen receptors coupled with the right levels of beard growth hormones may even grow you thicker beard sooner than expected.

So how can you increase the sensitivity of your androgen receptors?

Following some of these tips will also increase your levels of testosterone.

  • Resistance training
  • Eat macuna pruriens
  • L Carnitine
  • Vitamin D
  • Intermittent fasting

Read this article to learn more about how these tips help increase the sensitivity of your genes to facial hair growth hormones.

Get enough sleep

It is recommended that a man should sleep for about 8 hours a day for them to get enough sleep.

Lack of sleep has been proven to reduce the levels of testosterone in the body.

Therefore you must ensure that you are getting enough sleep and rest so as not to affect your testosterone levels.

Avoid stress

Stress leads to the production of cortisol hormone which has been known to reduce the levels of testosterone in the body.

There are several techniques that you can use to reduce stress such as working out or jogging.

Use derma roller and minoxidil/Rogaine

A derma roller will stimulate blood flow into your face, increase collagen production in your face which stimulates beard growth.

You should derma roll about twice a week. And in case you want to grow a beard faster you can incorporate minoxidil. Minoxidil has been proven and even approved by the FDA to help regrow hair.

The scientific test has even confirmed it can grow beards to those who are struggling to grow one.

Anecdotal evidence of before and after pictures of those who have used minoxidil shows it can actually work.

But still, there are a lot of controversies when it comes to growing a beard using minoxidil. In their website, they claim that hair grown using minoxidil is not permanent.

The site claims that you will lose your beard or hair grown using minoxidil once you discontinue its use.

Nonetheless, when you comb through the internet you will find anecdotal evidence of people who also claim that they did not lose their beard even after they stopped using minoxidil.

So my take is only to use minoxidil after all the other options have failed you.

Do you have to wait to grow old to grow a thicker beard?

No, you do not let aging determine how full your beard will get. There are several natural oils that can promote beard growth. But you have to be very careful since some oils available in the market are not even fit to grow a beard.

Natural oils such as castor oil, peppermint oil, olive oil, almond oil, grapeseed oil will help stimulate beard growth while argan, jojoba, coconut oil will help moisturize and groom your beard.

Keep away from oils that inhibit the activity of your beard growth hormones. These include pumpkin seed oil, tea tree oil, lavender oil, eucalyptus oil, rosemary oil, amla oil, which have been proven to inhibit the action of beard growth hormones. Some like tea tree and lavender were found to cause man boobs among young boys.


Do beards fill in overtime? Yes, if you are a late bloomer beard should fill in overtime. As you age your androgen receptors (genes) become more sensitive to the beard-growing hormones.

Can every man grow a full beard? Naturally not every man can grow a beard as some men have very lowly sensitive beard-growing genes. However, under the minoxidil, most men can grow a beard.

Why is facial hair more prominent in older men than young men? The reason older men can grow a more prominent beard as compared to young men is based on the sensitivity of their androgen receptors (genes) to facial hair growth hormones.
