Many men – when growing beard for the first time – notice that their facial hair is patchy, especially on the cheek area, just like Keanu’s on the image above.

How to fill in this patchy beard then? And also how to make sure that the trimming and beard style is right for thin or sparse or patchy facial hair that you have.

Why is My Beard a Patchy Mess?

patches in beard and how to fix patchcy facial hairLike said, this is an extremely common problem, and especially on the area of the cheeks.

There are few scientific reasons as to why peach fuzz beard and thin facial hair happens.

The most common of the patchy and sparse facial hair causes is that the cheek area has significantly weaker blood flow than the area of the upper lip and chin.

Meaning that over time less nutrients and beard growing hormones (testosterone and DHT) make it to the cheek area, resulting in beard patches and thinner facial hair on the cheeks.

Another explanation is that your overall levels of androgens (testosterone and DHT) might be on the lower end and the supply simply isn’t enough to trigger facial hair growth in full beard area. Common characteristics of men with lower amount of male hormones are indeed a thin beard, growth only on chin and mustache area, and/or no facial hair at all.

There’s also the issue of the androgen receptor (which we look much more closer below). Based largely on your genetics and some other factors which you might be able to influence, the receptor sites in your facial hair follicles that “receive” the hormonal growth signals might not be active enough to trigger beard growth, even if your blood flow and hormone levels would be high.

Will my beard ever fill in then? 

You may have heard people saying that it’s all in the genetics and there’s nothing that can be done to fix a patchy beard. However, there are several research-backed patchy beard solutions, and you’ll find them below.

1. Thicker Beard Secret: Minoxidil

make your beard thicker with kirkland minoxidilIf there’s only one trick that you’re going to implement from this list, make sure it’s this one.

Minoxidil (brand name Rogaine), is hands down the number #1 secret to fixing a patchy beard.

It’s the popular scalp-hair loss drug that’s available without a prescription, and hundreds of clinical trials have confirmed that the active ingredient when applied to scalp, grows more hair.

It works by opening potassium channels, which causes hyperpolarization of the beard follicle cells, which rushes in nutrient and hormone rich blood through significantly improved topical circulation.

Aside from this, minoxidil also boosts the size of hair follicle shaft, increases the diameter of the actual hair root, and encourages the follicles to shift from resting phase to the active growth phase.

So if minoxidil does all this to scalp hair, can it be used on face to fix a weak facial hair?

The answer is yes. It has been confirmed by hundreds of anecdotal before and after pics from various beard forums and also through a Thai study where 3% topical minoxidil solution was able to “significantly increase” new hair growth on face.

how minoxidil fixes patchy thin beard

Let’s say you will start using minoxidil, here’s a simple guide:

  • Get yourself either Rogaine 5% or Kirkland 5% minoxidil.
  • Apply 1-2ml twice per day to facial hair area. Leave for 4-hours.
  • Do this for 6-12 months, and you WILL gain much more facial hair.

2. Eat Like a King

patchy beard foodsNo, I’m not here to give you the usual BS you see in articles like this.

You know, the “drink more water, eat more protein and salad” sort of fart-winds.

Fact is that you can significantly increase testosterone levels and DHT levels to force thicker beard growth, by manipulating your daily nutrition habits.

How? Let me break it down:

2.1 Dietary Fats

Try eating more saturated and monounsaturated-fatty acids (meat, coconut oil, dairy, olive oil, butter) and less polyunsaturated fatty-acids (vegetable oils, fast food & frying oils, canola, corn oil, sunflower seed oil, processed margarines, etc).

There is a gigantic pile of scientific proof that shows very clearly how men who switch from vegetable fats to animal fats, see massive increases in their testosterone and DHT levels, aka the beard stimulating male sex hormones.

How much fat you ask? Research suggest that 20-35% of daily calories is optimal for androgenic hormone production.

2.2 Carbohydrates

It’s all the rage right now to go to “war against carbohydrates”, which is pretty bonkers, considering how vital glucose and fructose (which all carbs eventually break down to) is for the optimal functions of the cells and neurons.

Again, there’s a mounting pile of clinical data which suggests that the more carbs you eat, the higher your testosterone and DHT levels will go. This is especially true in active people, who seem to benefit even more from high carb consumption, and suffer even more from low-carb diets.

Here’s a nicely explained review of the scientific evidence, and to pick an important study out from there that directly relates to beard growth and fixing patchy facial hair, we can see that Anderson et al. found how higher-carb, lower-protein diets compared to higher-protein, lower-carb diets resulted in significantly higher DHT (the hormone that promotes linear beard-growth), and testosterone (the hormone that controls beard growth rate and primes facial hair follicles).

how carbohydrates can help sparse facial hair issues

We at Beard Resource follow and recommend every man interested in boosting their beard growth rate to get roughly 50-70% of their daily calories from carbohydrates; potatoes, fruit, pressed fruit juice, berries, etc.

2.3 Protein

As you might already guess from the above subheading, protein is actually the least important macronutrient for beard growth optimization.

This doesn’t mean that you shouldn’t eat it at all! Since chronic protein malnutrition has been shown to wreck your hormonal health, and the keratin and collagen that actually builds the hair shaft and roots, depend on protein.

However, you might want to keep your protein intake at moderate amounts, just enough to fuel your muscles and hair roots, but not too much that it would interfere with optimal hormone production.

The optimal for fixing patchy facial hair, seems to land somewhere between 15-25% of daily calories. If you practice heavy-weightlifting, you might want to bump this up to 30%, but by all means that should be the max if you’re not looking to worsen the sparse facial hair problem.

3. Fix your Mineral and Vitamin Intake

vitamins and minerals to help with sparce and patchy facial hair and mustacheTo fill in your patchy beard spots and finally thicken that beard, you want to optimize your micronutrient intake.

Above, you learned about the importance of macronutrients (protein, carb, fat), and to finalize your knowledge of beard nutrition it’s important that you understand the key role that micronutrients (vitamins and minerals) play in the big picture of beard follicle health.

In a perfect World, you would get all the beard boosting fat-soluble vitamins; A, E, D, and K2 from the foods you eat. However, with the modern food processing and factory farming, the levels of these vitamins in our food sources have dropped dramatically.

Also in a perfect World, you would get plenty of the water-soluble vitamins like C and the whole B-complex, but since traditional foods like liver are almost completely forgotten and people eat less whole fruits than ever, most people end up deficient in these key vitamins as well.

Lastly, if all things would be optimal, your body would be filled with DHT and Testosterone boosting beard hugging minerals like zinc, magnesium, boron, selenium, and iodine, but power-farming and depletion of the soils mineral content, has caused massive reductions in the availability of these important minerals from the foods sitting in our grocery store shelves.

The simple fix? 

High-quality multivitamin. And I mean actually good one, which has the micronutrients in good and correct amount in the most bio-available form.

4. Derma Roller to Promote Thickness

fixing patchy thin mustache and beardI’ve talked about the benefits of microneedling the beard couple times earlier on this website.

The idea is simple and recently there has even been scientific studies conducted on the subject.

So how it works is you get yourself a product called Derma Roller, which is a wheel with tiny needles you often see women use in spa commercials.

You then use the Derma roller on your facial hair area 2-4 times per week to puncture tiny wounds into the skin.

This doesn’t hurt or cause any scars, but it’s enough to trick the body into sending hormone and nutrient rich blood to the area to repair the damage, along with this, your follicles will get a boosted influx of keratin and collagen proteins, which can thicken the facial hair.

The trick is to combine microneedling with already optimized diet and minoxidil use. It’s like a triple whammy to make your beard thicker over time.

There’s a study about this, although it was conducted on scalp-hair.

5. Activate Androgen Receptors

androgen receptors and patchy facial hair solutionsLet’s say that you’ve fixed your diet & micronutrient intake to stimulate natural testosterone and DHT production.

And you’ve started microneedling + using minoxidil to promote blood flow and stimulate the facial hair follicles for growth.

What more can you do to guarantee that you will get rid of your patchy beard and turn it into a thicker mane naturally?

The answer is; natural activation of the facial androgen receptor sites.

What the heck even is an androgen receptor?

Well, before the androgenic beard growing hormones like testosterone and dihydrotestosterone can have any impact on your body, they need to go from the bloodstream into the DNA of the cell. To achieve this, your muscle tissues, skin cells, hair follicles, and so forth are all filled with something called; androgen receptors.

As the name implies, they are there to receive the hormone into the cell. If the hormones are the key, the androgen receptors are the lock. And even if you have a lot of keys, but the locks don’t work, you will open no doors, which in this case translates to simply having no actual effects in the body.

Best Styles for Sparse and Patchy Beard

why is my beard patchy and how to fill in a beardUntil your beard fills in, you may want to know what are the best styles for patchy facial hair to make beard appear fuller and thicker.

Goatee is a classic one, and it’s often used by the men who can’t grow hair on their cheeks so well.

If you wan’t to maintain a more fuller style and have some hair on the cheeks too, try trimming the hair to be the same lenght all-around the facial hair area.

Lastly, use a brush to tame the hair downwards, and something like castor oil to make it appear thicker.

One option is also to just roll with it, let the beard grow at its own phase despite the bald spots, much like Keanu Reeves does. This style might look odd at first, but its also rugged and perfectly acceptable.

Bottom line is that there are many styles to choose from, and depending the sizes and placements of your beard patches, different styles will suit different people.


Well, I hope this article helped you learn the methods to finally fix you patchy facial hair and turn it into a thick mane of mythical proportions.

To summarize the last 2000+ words:

  1. Use minoxidil, it’s the most effective trick of them all.
  2. Fix your diet to support natural testosterone and DHT levels.
  3. Supplement with multivitamin to cover your micronutrient needs.
  4. Use derma roller on the face 2-4 times per week to stimulate collagen.
  5. Further assist the process by stimulating the facial androgen receptors.
