Mustache Gap: How to Fix and Bridge The Gap With Style

Whether you want to grow out a luxuriously thick handlebar mustache or a thin chevron, a small mustache gap might stand in the way. Now there are plenty of reasons why you might see a strange gap in your mustache.

These factors can include genetics, poor shaving techniques, hormonal imbalance, and various others we will be getting into.

But the important thing to know is that there is a way that you can fix it. And in this guide, we will tell you what causes these issues and how you can solve them. So, here’s to your dream of a pristine mustache.


Types of Mustache Gap

A mustache gap, also known as a mustache window, is an area where facial hair does not grow, resulting in a gap or empty space in the mustache. Some of the most common types of mustache gaps include:

Mustache Gap in the Middle

Mustache Gap in the Middle

The first type can be fairly harmless if smaller since it can act as a partition for your mustache. However, it’s when this middle gap extends further than the philtrum, and having a mustache can be very difficult. The middle gap can be, unfortunately, common.


Mustache Side Gap

Other than parting the mustache in the center, it is also possible for people to have a side mustache gap. This will usually be a small spot that cannot allow the mustache to connect to the beard, or it can just make a gap off the side of the mustache.


Bald Spot

Bald spots can be small or big on your mustache in different places that do not allow hair to grow. They do not follow any specific pattern and are usually just a circle on your mustache. These can be especially tricky since they can form anywhere on your face.


What Causes a Mustache Gap?

Now that you better understand mustache gaps, we can get into what really causes them. The human body is a complex machine, so plenty of factors can affect how your mustache turns up or if it will have gaps. Some of the most popular causes include:

Hormonal Imbalance

A major contributing factor to mustache gaps is patchiness, which could result from low testosterone levels. Since testosterone is responsible for the growth of all sorts of hair on the body, having low levels can be responsible for you not being able to grow a full mustache.

An imbalance in testosterone can also affect the fullness of your mustache and general beard density. Hormonal imbalance itself could be the result of poor dietary choices and lifestyle choices.



Unfortunately, winning the genetic lottery has a much greater impact on how your mustache turns out than anything else you do. So if you have a mustache gap in an odd place, you might have inherited that from someone in your family.

As a result, your natural ability to grow a mustache will trump most efforts you make. However, that is not to say that you still can’t have a good mustache with unfavorable genetic makeup.


The Direction of Hair Growth

Your mustache can naturally grow in a certain direction, or you can train it to grow in a specific way. Some people even train their mustache to grow the wrong way without realizing it as they brush it aside with their fingers.

If you don’t consider the direction your mustache is growing in, you might remove hair that could help hide your gap.


Size of the Mustache

While obvious, it is still worth saying that the size of your mustache can accentuate the gap. More specifically, the gap will be less noticeable if you have a thick, dark mustache. On the other hand, a smaller and lighter mustache can make even the smallest gaps are much more visible.


Poor Shaving Technique (Patchiness)

It is also possible that the way you shave your mustache is causing patchiness, making the spots more noticeable. Patchy mustaches can be hard to style in a way that you could hide the gap. Things like using a rough razer or not using shaving cream can result in patchiness.


A Larger than Average Philtrum 

This is another factor that can just come down to your individual genetics. The philtrum is that little groove on your upper lip that connects your upper lip to the base of your nose. Some people can have a smaller philtrum; others can have a much larger one. And people who do have a much larger one will see that their mustache gap is much more noticeable.


How to Fix Mustache Gap

After reading about the factors that contribute to a mustache gap, you might need more time to be optimistic about how you can fix it. Seeing how one of the reasons you might have a gap is genetics, it’s understandable that you would feel that way. However, a few ways exist to fix your mustache, even if you weren’t lucky enough to win the genetic lottery.


Growing Long Mustache to Cover Gap

The most obvious thing you can do to cover up your mustache gap is to grow it. More specifically, you should let it grow, regardless of how messy it looks. Just be patient and give it some time; soon, you can have a mustache long enough to cover the bald spots.

You can encourage the growth of your mustache by brushing it and lightly oiling it daily. You won’t have to worry about covering that spot by training it to grow a certain way.  


Using Mustache Growth Products

Speaking of oiling your mustache, you can promote mustache growth by using various growth-stimulating products. These types of products can usually take the shape of balms, serums, or oils.

Along with promoting hair growth in specific areas of your mustache, it can also allow it to grow longer. And with a long mustache, covering up that gap can be a lot easier.


Hormonal Treatments for Mustache Gap

These can usually include dosing, but you should not do this at your discretion. Make sure you contact a medical professional first.


Mustache Wax for Filling Gap

Trimming and Shaping the Mustache for a Neater Appearance

Nutritional Supplement And Diet

Finally, A mustache gap due to poor nutritional choices can be improved with a proper diet chart or good nutritional supplements.

While there is no specific nutritional supplement that is guaranteed to promote mustache growth, beard growth supplements like biotin that provide certain vitamins, and minerals may support healthy mustache growth.
