When you are growing a beard, it just seems like forever until it becomes a beard that you are happy with. If you are in the early stages of growing a beard, fear not – there are plenty of things you can do to help your beard grow strong and thick!
It is common for a beard to fill in between 20 and 25 years old. 32% of men reported this age on an online forum. However, a significant number of people saw their beards develop and fill in well into their 30s.
In this article, we will go over all of the things you need to know about beards and age. I have also researched online forums and gathered all of the ages at which people said their beards stopped filling in.
How long does it take for a beard to fill-in?
Even though there is a significant amount of science and data around when puberty starts, there isn’t much data on the other end of the beard-growing spectrum. We are limited to forum posts and answers from anonymous users of different websites to try to grasp a typical age at which a beard stops filling in.
I took a look at the most popular sites online where people freely share personal information. I looked at Reddit, capital, and Quora, where people as a very similar question.
I created a series of different age ranges and tallied the responses from the different websites.
The result of going through all of the forums and noting down at what age people said their beard stopped filling in.
Data from forum posts (Reddit, Quora, Tapatalk, etc.)
|21 – 25||32|
|26 – 30||21|
|31 – 35||11|
|36 – 40||5|
Here are the main findings from my research on forums and polls:
You can see from the above table and graph that a significant number of people (about a quarter of the data collected) said that they had developed their beard completely before the age of 20.
Also discovered was:
- 32% of people who responded to these online questions said they had fully developed their beard somewhere between 20 and 25.
- If you are a little older than 25, there is also some hope for you.
- About 21% of people said they developed their beards between 26 and 30.
- A significant number of people said their beards grew fuller in later years of life.
You may be in the small percentage of people who have a continuation of filling in.
Many respondents said they are still awaiting their beards to fill in past 30. Many users comment that they cannot grow a beard, and several people may have to accept that they cannot ever grow a full beard.
Data from YouTube
I asked my youtube audience of over 6000 people what age they thought their beards stopped filling in and this was their response:
One thing that you’ll notice is that the majority of people said that their beards stopped growing in their 20s. Some people reported that their beards continued to fill in on their 40s.
The data collected from my YouTube audience is very similar to that reported by people in forums.
Does your beard fill in as you age?
It does not matter that they cannot grow a full beard for many beard growers.
If you lack some coverage on certain parts of your face, there are plenty of other options. You can select a beard style best supported by how your beard grows.
Every man can grow a beard – it just may not be the beard that they thought they would be able to grow.

This experience is, of course, just my experience, and the data presented in the table above will give you a much better representation of the general population’s ability to grow a full beard.
I feel like many men agree that as you get older, your beard fills in. From my own experience, I know that my beard was not as full or thick until I was in my early 30s.
My beard-growing experience has been paralleled by what my relatives have been able to grow at certain ages. Therefore, I would consider the genetic component of beard growth one of the most important components.
Will a patchy beard fill-in?
If you are under the age of 25 and your beard is patchy, do not worry! There is plenty of time for your beard to develop and connect.
It is a common issue that has no one answer suitable for everyone. Not everyone can grow a full, evenly spread beard.
It is quite uncommon to have the perfect coverage of beard hairs. If you speak to any bearded person, they will tell you all of the issues they have had to overcome to grow their current beard.
A patchy beard is likely to fill in if you are under 30. If you have reached the age of 30 and your beard still has patches, you can’t do too much.
If you want to know more about growing out and dealing with your patchy beard, check out my YouTube video where I discussed the six insider tips for patchy beard success:
Here are some of the things you can do if your beard has not filled in and you are concerned about it:
- wait for six months – sometimes we are our worst enemies, and we are constantly obsessed with trimming up and shaping our beards. If you find that you are developing patchy areas, wait. In these six months, you will get to understand whether or not you can cover up the patches with hair on either side of the patch.
- Choose a beard style that suits you – you should choose a beard style that suits your growth patterns. Remember to grow your beard and not someone else’s. Some great beard styles lack the cheek area, moustache, sides, or cleverly use fades to cover up problem areas.
- Keep it shorter in the troubled areas – if you have symmetrical trouble areas (for example, on your cheeks), you can cleverly use fades and short clippers to hide these issues behind a style.
- Use medication as a last resort – some people like to use products like minoxidil to develop their beard growth. Even though some people have significantly improved beard growth in certain areas of their face, all medication comes with potential side effects.
Following the above advice will make sure that you can grow a beard that you are proud of – remember that this may not be the beard you thought you would be able to grow.
Part of this beard growing journey is to grow a beard by assessing the strong and weak points and choosing a beard style that matches that growth pattern.
Try not to be swept in by scam beard growing products to cover patches. They almost always do not work in the way they say they will.
Products that can help fill in a patchy beard
You might want to think about employing products to make your beard appear longer and fuller. Hair fibres are a popular alternative for those who do not want to take medication like minoxidil.
Hair building fibres can be sprayed on the beard’s surface or shaken over it. Shaking the hair building fibres provides you more coverage over a larger area while using the applicator attachment allows you to apply it more precisely.
A puff of air delivers the hair fibres from the applicator to the hairs on your face.
These steps are how you use these fibres
- Hair fibres rely on static to attach to the hair, so dry and style it as usual. To guarantee optimal static attraction, the beard should be as dry as possible.
- Shake the hair fibres over the area you wish to darken or apply them using the applicator.
- Some formulas include a hairline optimiser, which can be applied to the beard’s edges for a more natural look.
- Gently pat the hair to disperse the hair fibres and prevent clumping.
- To assist the bonding between your hair and the fibres try using a fibre hold spray.
Genetics of beard growth – get an idea of if your beard will fill in
Take a look at your family members who can or cannot grow a good beard. This easy observation will be one of the best indicators for you of whether or not you can grow a beard. And also, be a good comparison so you can understand at what age your beard is likely to fill in.
The genes required to grow a good, thick and lush beard come from both your maternal and paternal (mum and dad’s) gene pool.
So the most important question to ask yourself is if any of your relatives have a great beard.
The issue is that the inheritance of genes can get pretty complicated.
We even get a very small number of genes from even more distant relatives. You share about 0.78% of your DNA with your great-great-great-great-great grandfather (aka 5th great-grandfather). So, even though it is very unlikely that your beard growing potential comes from your great-great-great-great-great grandfather – it is a possibility.
That is why siblings may sometimes have a different appearance despite having the same mother and father.
At what age does your beard stop getting thicker?
The human male has two types of hair covering their body.
Firstly, there is an ultrafine, un-pigmented short hair known as vellus hair. The other hair is thick, long, and pigmented, known as terminal hairs.
Testosterone can turn these fine hairs into dark and thick hairs as long as they are sensitive to the hormones produced by the body after puberty.
That is because your testosterone levels and the receptors at the hair base are what dictate how thick the beard gets. To understand how testosterone changes as we age, check out this table.
Here is a breakdown of the testosterone levels in men at different ages from this source.
|Age Years||Total Testosterone Average Range||Normal Total Testosterone|
|30 – 40||219 – 1009 ng/dL||600 – 675 ng/dL|
|40 – 50||201 – 993 ng/dL||500 – 550 ng/dL|
|50 – 60||170 – 918 ng/dL||400 – 450 ng/dL|
|Over 60||156 – 700 ng/dL||300 – 350 ng/dL|

Do beards get darker with age?
One thing that may help your beard fill in is the darkness of the hairs that can increase the appearance of density.
Your beard colour is determined by the pigmented molecules produced in the hair follicle as the hair is made.
When you first start developing a beard, the hair will continue to get thicker as it changes from the light vellus hairs all over the human body to terminal hairs – the hairs that we are familiar with when we think of a beard.
There is no evidence to suggest that beards get darker with age beyond what happens at puberty. Although they can change colour due to the malfunctioning and age of pigment creating cells in the hair root.
It is quite normal for hair to change colour as you age, with the most likely option being that your hair will become lighter and grey from your mid-30s onwards.
What the science says about beard growth
Because there is a huge range of when people go through puberty, there is also a large range of when men can expect their beards to become fully developed.
A scientific study published in 1980 looked at the normal ages of pubertal events among American males and females.
The study looked at 36 males and 18 females examined at six-month intervals during five years.
They found that men’s median age at which they developed facial hair was 15 years old. 20% of the boys investigated had facial hair at 13. By about 16, 95% of the men had facial hair.
Considering that this is the onset of beard growth in males, it is clear that there is plenty of opportunity in future years for your beard to become thicker and fuller.
A more recent study published in 2010 found that black boys developed secondary sex characteristics about seven months earlier than Caucasian boys.
These studies demonstrate a clear difference between the genetics of different nationalities, which could indicate why we see a significant difference in the production of a beard between people of different races.
There is no doubt that genetics plays a huge role in determining your beard growth and it is something that you cannot fight.
Your beard should continually fill in until about the age of 25. According to our research, some people have also said that their beard continues to fill in past the age of 30, but this is unlikely.
If you find that you have a patchy beard, there are plenty of things that you can do to make sure that your beard grows in an intentional looking way which, ultimately, will be the thing that makes it look better than a long beard that is struggling to achieve a good density.
