You’ve been there. You're sketching a portrait, things are looking halfway decent, and then you try to add the facial hair. Suddenly, your realistic face looks like a potato wearing a cheap disguise. Honestly, it’s frustrating because we see mustaches every single day, yet when the pencil hits the paper, our brains revert to drawing a flat, black slug sitting above the lip.
The real trick is understanding that a mustache isn't a single object. It's thousands of tiny, individual tubes of protein—hair—interacting with light and the weirdly complex anatomy of the human face. If you want to know how do you draw a mustache, you have to stop drawing "a mustache" and start drawing hair growth patterns and skin shadows.
Why Most People Get the Philtrum Wrong
The philtrum is that little vertical groove between your nose and your upper lip. Most beginners ignore it. They just draw a horizontal line of hair right across the top of the mouth. Big mistake.
In reality, hair grows away from the center of that groove. It fans out. If you look at high-resolution reference photos—the kind professional portrait artists like Stan Prokopenko or the late Andrew Loomis would use—you'll see the hair doesn't just sprout straight down. It follows the curve of the lip. It arches.
Drawing the philtrum correctly means leaving a tiny bit of space or thinning the hair density right in the middle. This creates a three-dimensional look. Without it, the mustache looks like a sticker. It lacks the "heft" of real anatomy. You’ve gotta respect the skin underneath.
The Anatomy of the Follicle
Think about how hair actually sits on the face. It’s not glued to the surface. It emerges from a pore, usually at an angle, and then it drapes.
Texture and Stroke Length
If you’re using a 2B pencil or a digital brush, your instinct is probably to make long, sweeping strokes. Don't. Unless you're drawing a 19th-century handlebar mustache that’s been waxed into submission, the hairs are going to be varied. Short strokes. Tapered ends.
Each flick of your wrist should represent a few hairs, not the whole thing. Start with a light, hard lead like an H or HB to map out the "flow." This isn't about detail yet; it's about direction. Is the hair coarse? Is it soft? Real hair has "lost and found" edges. This means some parts of the mustache will be very sharp and defined, while other parts—usually where the light hits directly—will sort of blur into the skin.
Lighting and the "Shelf" Effect
A thick mustache acts like a shelf. It catches light on the top edge and casts a shadow on the lip below. This is where most drawings fail. If you don't include that tiny sliver of shadow between the bottom of the mustache and the top of the lip, the mustache will never look like it's actually attached to the person.
It’ll just look like it’s floating in front of them. Kind of spooky, right?
Different Styles Require Different Physics
A pencil mustache (think Clark Gable) is basically just a shadow. You aren't drawing much hair at all; you're drawing the darkness of the follicles against the skin. But if you’re going for a full-on Sam Elliott "Walrus" look, you’re dealing with gravity.
In the Walrus style, the hair is heavy. It covers the vermillion border (the edge of the lip). You have to draw the hair overlapping the mouth. This is tricky because you still need to suggest the mouth is there without making it look like the character is eating a squirrel.
- The Handlebar: Requires a "swoop" motion. The hair is bundled. Instead of individual strands, draw it as clumps that taper to a point.
- The Stubble: It's all about dots and very short ticks. Use a stippling technique but keep it random. Nature hates perfect patterns.
- The Chevron: Thick, wide, and slightly messy. Use a softer pencil (4B) to get those deep blacks in the core of the mustache.
Don't Make It Solid Black
The biggest "tell" of a beginner artist is using a solid black mass. Even the darkest hair reflects light. If you look at someone with a jet-black mustache under a lamp, you’ll see highlights—blues, greys, or even warm browns.
Use an eraser. A kneaded eraser is your best friend here. Pinch it into a sharp point and "draw" with it. By lifting lead off the paper, you create highlights that look like individual shiny hairs. It’s much more effective than trying to leave white space while you're shading.

The Role of the "Middle Tones"
Between the skin color and the darkest part of the hair, there’s a transition zone. This is where the magic happens. If you transition too sharply from skin to hair, it looks fake.
Gradation is key. You want some "stray" hairs that break the silhouette. Nobody has a perfectly groomed mustache that looks like it was cut with a laser. A few flyaway hairs on the edges make the drawing feel alive. It adds that messy, human quality that AI often struggles to replicate perfectly without looking "too" perfect.
Common Mistakes That Kill Realism
People often forget that the skin under the mustache is in shadow. Even if the hair is thin, the cumulative effect of all those follicles creates a darker base tone on the skin itself.
- Ignoring the Nose: The mustache should relate to the nostrils. Often, the hair grows right up to the base of the nose. If you leave too much gap, it looks like the mustache is sliding down the face.
- Symmetry Overload: No face is perfectly symmetrical. One side of the mustache might curl slightly differently or be a bit thicker. If you copy-paste the left side to the right side in a digital drawing, it looks uncanny and robotic.
- The "Fence" Look: This happens when you draw all the hairs perfectly parallel. It looks like a picket fence. Real hair crosses over. It tangles. It goes in slightly different directions.
Tools of the Trade
If you're serious about getting this right, you need the right gear. A mechanical pencil with 0.5mm lead is great for those fine, individual hairs. For blending, don't use your finger. Your skin oils will smudge the graphite and make it look muddy. Use a paper stump (tortillon) or even a dry paintbrush to soften the shadows underneath the hair.
For digital artists, turn off the "taper" on your brush occasionally. Or better yet, find a "rake" brush. These brushes have multiple points and allow you to lay down several hair-like strokes at once, which you can then refine by hand. It saves time but requires a steady hand so it doesn't look like a texture stamp.
How to Handle Different Colors
Drawing a blonde mustache is a nightmare compared to a dark one. With dark hair, you're drawing the hair itself. With blonde or white hair, you're actually drawing the shadows between the hairs.
You have to be incredibly subtle. You’re essentially carving the shape out of the paper using negative space. Use a very light touch. A 2H pencil is perfect for this. Focus on the base of the hair where it meets the skin—that’s where the most contrast will be.
Putting It Into Practice
Start by sketching a basic nose and mouth. Don't even think about the mustache yet. Get the underlying structure solid. Once the "foundation" is there, lightly map out the boundaries of where the facial hair will go.
Check your angles. Does the mustache follow the perspective of the face? If the head is tilted, the mustache has to tilt with it.
Now, begin your "directional strokes." Start from the philtrum and work outward. Keep your pencil sharp. Every five or six strokes, rotate your pencil to find a new sharp edge.
Finally, add the "overlap." Let some hairs hang over the top lip. This is the single most important step for realism. It breaks the hard line of the mouth and makes the hair feel like it has volume and weight.
Actionable Next Steps
To truly master this, stop drawing from your head. Your brain lies to you about what a mustache looks like. It gives you a symbol, not a reality.
- Go to a site like Pinterest or Unsplash and search for "male portrait close up."
- Zoom in until you can see the individual pores.
- Trace the direction of the hair growth with your finger on the screen. Feel the flow.
- Try to replicate just a small one-inch square of that mustache. Don't draw the whole face. Just the texture.
- Experiment with different weights. See how a 6B pencil creates a different "vibe" than a HB.
Once you get the hang of the physics—the way hair grows, falls, and catches light—you’ll realize it’s less about "drawing hair" and more about drawing the behavior of hair. Stick with it. Facial hair is one of the most expressive parts of a portrait, and getting it right changes everything.
