What Age Beard Stops Filling In: [No BS, The Truth]

Poets and authors have described the magnificence of a full flowing beard for ages. However, not all of us are lucky enough to enjoy the benefits of a full and amazing beard in all its glory.

A patchy beard can, not only physically single you out for stares and comments, but it can also be a source of mental agony. Genetics, age, and hormones all play an important role in determining the kind of beard that you’ll have.

Most teenagers and young men are obsessed with questions like these…When does my beard stop filling in? At what age, does my beard stop developing? At what age do beards grow fully? And much more…

A beard normally stops filling in by the age of 30. In fact, many men can’t even develop a reasonable beard before the age of 23. Most men start growing facial hair in puberty, around 13 years of age but this process continues for many more years.

Also, keep in mind that just because your beard is not thick and complete by the age of 20, it doesn’t mean the game is over. Stay positive and patient.

Here in this article, we will try to answer all your questions regarding how to grow the perfect beard. In short, if you don’t have much time, my answer to your question is that if you are not yet around 30 years old, your beard can still thicken. This is the truth.

But, if you wanna learn more details keep reading!

I will help you understand the science and the art behind growing a beard so that by the end of this blog post you’ll have gleaned valuable information that you can put into action straight away. 

When does my beard stop filling in

At What Age Is Your Beard Fully Developed?

There are three stages of hair growth in the human body. They are called anagen, catagen, and telogen. 

In the anagen phase, there is a rapid growth of the hair. 

In the catagen phase, hair growth is dormant. This is also the stage where your bread stops thickening or growing. 

In the telogen phase, new hair replaces older or dead hair to kick-start the process of hair growth once again. 

Depending on your age, race, and genetics, the above phases will occur differently in different people. 

All of this stuff is written in books and I have personally read a lot of books, studies and posts before I was able to form an opinion on the topic.

We have also made a detailed analysis on posts from Q and A sites like Quora, Reddit and Tapatalk.

We were searching for posts that men clearly answer the question of at what age their beard stopped developing. Here is what we have found.

This Graph is not by any means reviewed by doctors therefore it may not be 100% accurate. The testosterone stats are from the ”Androgen Decline In The Aging Male” chapter of this Urology book, Medicalnewstoday.

But what do all of these numbers tell us?

  • There is a clear correlation between testosterone levels and beard growth
  • Facial hair has stopped thickening by the age of 30 in 75% of men according to them.
  • Everyone is different and the results vary a lot.

There is a significant number of men that have developed a thick beard later on. So, if you are still a teenager or a young adult and you are desperate about growing a beard, just keep in mind that hope is not lost.

And let me also tell you something else.

The men that have stated that their beard has stopped developing at age 18-20 were still young and I am very unsure if I can trust their opinion.

Obviously, their beard growth rate might be lower than before but that does not mean that no more new hairs grow after 18 or even 20 years of age.

Our take on the topic is this.

If you are younger than 30 years old there is a good chance that your beard will thicken. There are even some exceptions as you can see in the graph that we’re able to grow a thicker beard after the age of 30!

So, don’t lose your hope too early!

Does your beard stop growing or grows slower as you age? 

If you were curious to know about this, the answer is facial hair tends to grow slower. While hair never completely stops growing, the rate at which hair grows does change with age. 

Over or under-active hormones can be responsible for affecting hair growth, while factors such as genetics and ethnicity also play a role in how sooner or later will your beard stop thickening. 

Don’t think, however, that your beard will grow slower by the age of 30-40. Your facial hair will grow at a slower pace after at least 50-60 years of age as your testosterone levels will dramatically drop.

You will have maximum beard growth and thickness by the age of 25-35. This will be your peak as far as your beard growth is concerned.

At What Age Does Beard Grow Fully?

Your genes are one of the critical factors that determine how much time your beard needs to grow fully.

It is as if there is a program in our genes that determines whose hair will grow at what rate and what thickness. It is our genetic code that includes information about everything such as appearance, height, skin color, etc…

Therefore, everyone has a different quality of growth. Hairs grow at an average of ½ inch per month, and depending on your genes and also on how long you want it to grow, it could take anywhere between a few months to a few years. 

Ethnicity also plays a role. For example, it is seen that people from the Mediterranean region grow thicker beards than other people across the world. 

However, that is not all. Beard growth could also be affected due to illnesses such as alopecia areata. For example, the condition of a patchy beard is more often than not due to alopecia areata.

Alopecia areata is a condition where the body’s immune system thinks that hair follicles are not good for the body and starts shedding them. While the causes behind this illness are still unknown, doctors think that stress could be one of the main factors that lead to it.

The short answer to the above question is that the time taken grow your full beard is dependent on many factors such as age, your race, and your genetics.

In general, most men have maximum beard growth during the ages of 25 to 35. However, the belief that as you grow older beard growth decreases is a misconception, and hair never truly stops growing but the rate at which they grow does change.
