It’s a question that has been asked for centuries: can beard hair stop growing? And if it can, what can be done to make it start again? In this in-depth article, we will explore the science behind beard growth, and answer these questions once and for all so that you can have the best and fullest beard possible.

What Causes Beard Growth?

At its most basic level, a man’s beard growth is a combination of genetics and hormones. To grow a beard, you must have the right mix of both. Some men are simply not genetically predisposed to growing facial hair, no matter how much they may want to.

Others may have the genes for it, but their hormones are not in alignment for beard growth. Testosterone is the main hormone responsible for facial hair growth, so if your levels are low, it could be the reason why your beard is not as thick or full as you would like it to be.

External Facial Hair Growth Factors

There are also external factors that can cause beard growth to slow down or even stop completely, including:

  • Excess stress
  • Poor nutrition and diet
  • Certain medications
  • Genetics

If you are experiencing slowed or stopped beard growth, it is important to look at all of these factors to see if any of them may be the cause.

Excess Stress

Stress is a part of life, and sometimes that stress can be difficult to manage. For some individuals, chronic stress can even negatively impact the body, including limiting beard growth and slowing hair growth in other areas of the body. This happens because when stress hormones are elevated for long periods, they inhibit stem cell activity in the hair follicles.

This means that there is simply not enough energy to fuel robust beard growth or increased hair growth elsewhere. Furthermore, high levels of stress can suppress appetite and diminish overall health, making it harder to achieve optimal beard thickness and length.

But with some simple lifestyle changes and stress-reducing techniques, it is possible to reduce those stress hormones and allow your facial hair to flourish. So if you’re feeling stressed out about your beard (or lack thereof), just take a few steps back and focus on reducing your overall stress levels for maximum facial hair success. Remember that a healthy body is necessary for a healthy beard and thicker hair.

Poor Diet

Anyone who’s ever tried to grow a beard knows that it’s not always an easy task. In fact, several factors can affect the rate of beard growth, including hormones, genetics, and yes – even diet and nutrition. Poor diet and nutrition is a huge factor that can limit beard growth in several ways.

For one thing, inadequate intake of proteins and other nutrients can lead to slower hair growth. Additionally, certain vitamins and minerals are essential for healthy hair follicles, so a deficiency in these nutrients can also impact beard growth.

Finally, unhealthy eating habits can cause inflammation throughout the body, including the facial hair follicles of most beards. So if you’re looking to maximize your beard-growing potential, be sure to Eat Right with a balanced diet.


For many men, growing a beard is a rite of passage. It’s a way to assert their masculinity and show the world that they’re no longer boys, but men. However, some men find that their beard growth is limited by certain medications.

For example, certain acne medications can cause hair follicles to shrink, resulting in less beard growth. In addition, some blood pressure medications can also affect hair follicles, resulting in reduced beard growth.

While these medications may be necessary for some men, it’s important to be aware of their potential side effects. For those who want to maximize their beard growth, it may be necessary to switch to alternative medications or pay extra close attention to their beard care.


If you’re one of the many men who have always dreamed of sporting a thick, luxurious beard, you may be disappointed to learn that your genes could be working against you. Studies have shown that beard growth is largely determined by the level of testosterone in the body.

Testosterone is a hormone that is responsible for many male characteristics, including facial hair growth. So, if your father or grandfather was clean-shaven, it’s likely that you will be as well. Additionally, research has shown that ethnic background can also play a role in determining how much facial hair you’re able to grow.

For example, men of Caucasian descent are more likely to have full beards than men of Asian or African descent. This is merely because the genetic mutation responsible for full beards is more common in men of Caucasian descent.


Just as the hair on your head can thin out and eventually fall out as you age, the same process can happen with your facial hair. Beards are just another type of hair, so it stands to reason that they would be affected by the aging process.

The hormone testosterone plays a role in both head and facial hair growth, and levels of testosterone naturally decline as men get older. This can lead to a reduction in beard growth or even complete cessation of beard growth in some cases.

So if you’re wondering why your grandpa is clean-shaven while your dad still has a full beard, it’s because he’s probably older and his testosterone levels have decreased to a certain point.

Other factors can affect beard growth as well, such as certain medical conditions and medications. But aging is one of the most common reasons why beards may become thinner or stop growing altogether.

Can Beard Hair Stop Growing?

Even if your diet is good, you aren’t taking any medications that affect beard growth, or your father and grandfather both had full beards, there’s still a chance that your beard hairs could stop growing. To understand how that happens, it’s best to understand something called terminal beard length.

Terminal Beard Length

Terminal beard length refers to the point at which a beard stops growing and becomes fully formed. It’s your beard’s maximum length. This varies from person to person, depending on many factors such as genetics, nutrition, and hormonal health.

Generally speaking, the terminal length for most men is somewhere in the range of 6-12 inches. Therefore, if you are trying to grow out your beard and want to determine when it can be considered “fully grown,” you should look for signs that your beard has reached this length.

Some common indicators include a well-defined color contrast between the hair on your face and the rest of your head hair, or an abundance of hair follicles along the cheeks and jawline. Additionally, the hair should be growing evenly all around the face, rather than patchy or spotty. Once you’ve reached this point, it’s likely that your beard has reached its terminal length and will not grow any longer.

Of course, there are always exceptions to the rule. In some rare cases, men have been known to grow beards that are much longer than the average terminal length. But for the most part, if your beard is not growing any longer past a certain length, it has probably reached its full potential.

What to Do if Your Beard Stops Growing?

If your beard has stopped growing and you’re not happy with its current length, there are several options available to help you achieve your desired look.

Alter your Diet

First, you can try altering your diet or taking supplements to improve your overall health and promote beard growth. Eating a healthy diet and getting enough vitamins and minerals is essential for maintaining good overall health and for promoting facial hair growth.

Additionally, certain supplements have been proven to help with beard growth. These include biotin, vitamin B5, vitamin E, and vitamin D. You can find these supplements in pill form at most health food stores or online. Try taking them for a few weeks or few months and see if it makes a difference in your beard’s growth cycle.

Consider Laser Therapy

Another option is to consider laser therapy, which many men have used successfully to grow thicker, fuller beards. This treatment involves using a low-level laser to stimulate the facial hair follicles and encourage beard growth.

Laser therapy is a relatively new treatment, so there is not a lot of long-term data available yet. However, early studies have shown that it can be effective in stimulating beard growth in men with genetic conditions that cause facial hair loss.

If you are interested in trying laser therapy, make an appointment with your dermatologist to discuss whether it may be a good option for you.

Rock the Beard You Have

Finally, if you’ve tried all of the above and your beard still isn’t growing the way you want it to, don’t despair! Maybe a long beard isn’t in the cards for you. Embrace the beard you have, and take steps to embrace your natural look.

This can involve styling and trimming your beard in different ways to help it look its best, or trying out facial hair accessories that can help you look and feel your best. I’m a firm believer that the beard fits the man, meaning that any man can rock the beard he has, even if it’s not quite the length that he wants.

So don’t fret if your beard has stopped growing. Instead, take steps to make the most of what you’ve got.


Overall, whether your beard stopped growing or not depends on many factors. If you have reached the terminal length, there is not much you can do to make it grow any longer. However, you can take steps to improve your overall health and promote beard growth, including changing your diet, taking supplements such as biotin or vitamin B5 and vitamin D, or trying laser therapy.

Ultimately, if your beard has stopped growing, it’s important to embrace the beard you have and make the most of it, rather than trying to force your beard to grow longer.
