Many men have used it and seen improvements in their beard growth.

But what is biotin?

How does it work?

What does it do to your beard?

Keep reading to find the answers to all of those questions and more.

What Is Biotin?


Biotin is also known as Vitamin B7 and is essential to many of the body’s various functions.

While it helps us to metabolize a variety of different parts of our diet, aids in the growth of fetuses, and helps with skin health, it does something that we are a little more interested in… Improving hair growth.

How Do We Get Biotin?Old man eating



Biotin is found in the food that we eat.

There are however, very little amounts of it available in our daily diet.

Thankfully, you can increase your biotin intake in several different ways.  The most common way to get extra biotin in your system is through pills and supplements.

There are a wide variety of them out there designed just for beard growth.

Another option for getting biotin is through oils.

These oils are designed to make facial hair grow faster.

However, there is no evidence to suggest that topical creams work any better than a pill form. So it really comes down to your personal preference.





As we mentioned earlier, biotin can definitely help with hair growth.

It does this by helping to strengthen keratin in your body. This is the most scientifically proven benefit of biotin in that it is known to support keratin growth.

It doesn’t just do this in hair, it also helps your nails to grow. Nails are also made of keratin, so the stronger the keratin in our body, the stronger our nails are.

The same goes for your hair.

What biotin isn’t going to do is magically grow your beard overnight. Biotin supplements for beard growth are designed to help improve the speed and quality of your facial hair growth, and not an instant miracle formula.

Biotin should also help you to grow a thicker beard. Meaning that it will help to fill in some of those stubborn patchy areas on your face where hair refuses to grow without that extra boost. Most of us have one or two problem areas on our beards that don’t seem to grow out properly.

You will also notice that your facial hair has a better appearance. Healthier hair always has a smoother, more appealing appearance. The hair on top of your head will too!

These benefits have been proven several times in studies. Not all of the studies are directly on facial hair, but they do carry over.

One study on scalp hair showed that those who took biotin showed almost double growth and thickness from those on a placebo.

Other studies have been conducted that show similar results.

Why Do A Lot Of People Have Trouble Growing Facial Hair?


There are plenty of people who have trouble growing facial hair.

One of the main causes of this is biotin deficiency. Just like any other vitamin in the body, you can be deficient in biotin. Those who are deficient can experience a variety of symptoms when growing their beard out.

Such as:Guy with patchy beard

  • Facial Hair loss
  • Reduced or no Facial Hair Growth
  • Brittle/Weak Facial Hair
  • Gaps in Beard Growth

If you believe that you have biotin deficiency you should go to a blood lab and have your levels tested.

In many cases your insurance does not require that you have a doctor’s order to have blood drawn if you use the right facilities (one of the biggest labs on the West Coast of the United States for such processing is PACLAB).  Once the results come in, confer with your doctor to determine the proper levels.

Often times the lab results will show whether you are low, average, or high on any of the testing you are conducting.  However, a doctor’s opinion on your specific levels is always the best.  Also ask your doctor how much biotin you should be taking in order to correct a deficiency.

What is the Correct Biotin Dosage for My Beard?




As with any vitamin, you can have too much biotin.

Too much biotin can cause a variety of symptoms so taking the right amount is crucial.  For the best beard growth results, you should always follow the instructions included in whichever biotin supplement you end up using.

On average, doctors recommend that you take 2.5 mg of biotin a day.

This is just for general biotin supplementation, and is not specifically targeted towards beard growth. Some doctors will recommend up to 5 mg of biotin a day for beard growth.

However, you should always speak to YOUR doctor and as an additional precaution, check to see if any daily supplements that you take already contain biotin and adjust accordingly.

Biotin is considered as a fairly safe vitamin to take. As It is something that most people’s bodies are lacking.  But like with most supplements, excessive levels of biotin can still lead to negative effects on your body.

Biotin Overdose Side-Effects



  • Skin reactions such as rash of flushing
  • Excessive need to urinate
  • Lower levels of other vitamins
  • Elevated blood sugar levels
  • Slowed release of insulin



What to do if You Accidentally Overdose?


You should seek professional care immediately for any overdose.

Additionally, you can start by drinking a lot of water. Biotin is very water soluble and increased water levels can help you to correct an overdose.

This should also help to replace the water lost from excessive urinating.

Don’t Shave


When trying to gain rapid beard growth, a lot of people actually believe that you just need to shave a few times to increase the speed at which your beard grows.

This is a myth and one that can actually slow down the amount of time it takes to grow out your beard.

Leave your facial hair alone until it is grown to the length that you desire. Then you can start styling it.

Use A Beard Oil


A lot of people aren’t aware of the direct benefits of biotin and as a result, end up using other oils to help with their beard growing.

There are a variety of beard oils on the market that are designed to help keep your beard hair healthy and to increase its growth.

Using biotin alongside a beard oil should help in achieving positive results.

Wash Your Face DailyWash Your Face


Washing your face daily helps to keep your pores from blocking up.

Blocked pores are one of the major reasons which prevent hair from growing out and often lead to in-growns.

You don’t want to just simply rinse your face off though.

Invest in a mild skin cleanser to help get that debris away.  Some experts even recommend using a cleanser twice a day.

Conclusion: Does Biotin Help Beard Growth?

YES, it does!

And if you haven’t already looked into it, you need to seriously consider adding an effective biotin supplement to your daily diet if you are looking to grow a beard.  It won’t just help speed up growth, it will help the hair that grows to be healthier and fuller.

Things that every man wants and deserves in their beard.
