The Mustache Gap: What is It & How to Fix It


Mustache Gap

Are you seeing a mustache gap? It’s not just your mustache that’s looking a little off – hair on your upper lip is also growing less densely, leading to a noticeable difference in facial hair.

The mustache gap happens when the hair growth in the “philtrum area” (or cupid’s bow) is less dense, resulting in a visible gap between the mustache and upper lip. While there are a few factors that contribute to the mustache gap, most of it can be fixed with proper hair-growth techniques.

So what can you do to reduce or even eliminate the mustache gap? In this post, we’ll discuss the causes of the mustache gap and provide tips on how to fix it. Keep reading to learn more!

What is a Mustache Gap?

A mustache gap is the small space between the nose and upper lip that’s left exposed when a person grows a mustache. The term can also be used to describe the hairless area on a man’s face that’s often seen as the ideal place to grow a mustache.

What Causes the Mustache Gap?

The mustache gap is caused by a combination of factors, including genetics, puberty, weight loss, aging, and shaving. The best way to reduce the appearance of a mustache gap is to grow a mustache that covers the gap.


Mustache growth is heavily determined by genetics. This means that no matter how much you try to grow a mustache, your natural ability will always be greater than what you can achieve with efforts alone.

However, there are a few things that you can do in order to help the process along – from eating right and maintaining healthy facial hair growth to using the best products regularly.

Large Philtrum

A large philtrum is a vertical groove in the middle of the upper lip that extends from the base of the nose to the border of the lips. It’s a common facial feature and can vary in size from person to person.

Large philtrums are commonly perceived as less attractive and why men will grow mustaches.

Growth Direction

Mustache growth direction is the direction that your mustache hair will grow in. It’s important to take this into account when you are trimming your mustache, as you will want to ensure that you are trimming it in the direction that it’s growing.

Hair Density

Mustache hair density is a measure of how much facial hair you have. The denser your facial hair follicles, the more likely it’s that your beard will be thicker and fuller. The mustache gap may be caused by a lack of hair density below the nose.


A patchy mustache is a mustache that does not evenly cover the upper lip. It’s often the result of poor shaving technique or genetics. Patchy mustaches can be difficult to style and often do not look as good as a fuller mustache.

Typically, you’ll also have an accompanying patchy beard and may find it difficult to grow a full mustache and a full beard.

Low Testosterone Levels

Low testosterone levels can cause patchy facial hair growth, as well as a wide mustache gap. Testosterone is responsible for the growth of facial hair and plays an important role in maintaining beard density and fullness.

Mustache Color

The mustache gap is the space between the top of the lip and the bottom of the nose. The color of your mustache can affect how noticeable this gap appears.

If you have a very light mustache, the gap will be more visible. If you have a very dark mustache, the gap will be less visible.

How to Fix a Mustache Gap?

If you have a mustache gap, the first thing you should do is to assess whether it’s actually a problem. If it doesn’t bother you, then there’s no need to do anything.

However, if you’re self-conscious about it, there are a few things you can try to get your self-confidence back. Our tips below are reasonable and actionable without being too drastic like a beard transplant.

1. Grow it out

If you have a mustache gap, the first step is to grow out your mustache. This will help you determine how much hair you need to fill in the gap. Once you’ve grown out your mustache, you can start trimming it to create the desired shape.

2. Trim the top line

To help a mustache gap at the top of your lip, the best way to fix it’s by trimming the top line of your mustache. This will ensure that your mustache is covering the entire top lip. Trimming will also reduce the mustache height and will make the gap less noticeable.

3. Use Mustache Dye

If you’re self-conscious about the mustache gap, you can try using mustache or beard dye to cover up the gap. Mustache dye comes in a variety of colors and will give your facial hair a more natural appearance. Just be sure to apply enough beard oil or balm so that it doesn’t leave behind any residue.

4. Fill in with Hair Fibers

If you are looking to fix the mustache gap, you need to try hair fibers, AKA beard fillers. This will help recreate the natural texture and density of facial hair, thereby achieving that fuller mustache style.

There are various fiber products on the market that can achieve this goal, so it’s important to do your research before making a purchase.

5. Use Mustache Wax

Also called stache wax or beard wax, mustache wax is a good way to shape your mustache hair into place. The first step is to warm up the wax by rubbing it between your fingers.

Then, apply the wax to your mustache, starting towards the middle and working the hair into the bare gap area. Use a comb to distribute the wax evenly.

6. Improve your Diet

If you’re struggling to fill in the mustache gap, you may need to improve your diet. A full and healthy beard will help fill in the gaps between facial hair strands, which will result in a fuller mustache.

Include plenty of vitamin E-rich foods like nuts, avocados, and olive oil in your diet to help support beard growth.

7. Try Vitamins & Supplements

Mustache growth is often attributed to the intake of vitamins and supplements. However, not all vitamins are created equal with beard growth. In fact, some of them have been specifically designed for this purpose.

When selecting a vitamin or supplement for facial hair growth, include Vitamin A, Vitamin D and E, which are known as essential nutrients for \ hair follicles. Some other key ingredients might also include Co-enzyme Q10, caffeine or Biotin, which can also promote mustache growth.

8. Try Mustache Growth Products

Mustache Growth Products are products that help you grow a mustache. Some common mustache growth products include creams, oils, and serums. These products can help you grow a thicker, fuller mustache.

Be sure to read the ingredients carefully before purchasing any product. Look for natural products that are free of harsh chemicals.

9. Use Minoxidil

If you’re looking for a solution to the mustache gap, minoxidil may be just what you need. Minoxidil is a medication that’s used to promote hair growth in men and women with certain types of hair loss. Minoxidil is available in a topical solution that’s typically applied to the scalp or face.

This topical solution helps grow facial hair and has worked for men. Simply apply it as directed. Be patient, as results will take time to show. Always consult your doctor before starting any treatment.

Maybe you can just avoid the mustache gap altogether. One option is to try a beard style without a mustache. This will allow you to style your look with maybe a goatee, chin puff, or soul patch.

There are plenty of mustache-free beard styles available, so there’s no need to panic about the mustache gap.

Step 2: Moisturize

Mustache hair is naturally dry and needs moisture to stay healthy.
