Ever catch yourself staring at a guy and wondering, ‘How are his lashes that long?” You’re not alone! Many people wonder why men seem to have longer or fuller eyelashes. But here’s the twist—it’s not really about being male.
Men tend to have longer eyelashes due to higher levels of testosterone, which can stimulate more hair growth, including around the eyes.
Let’s break it down.

It’s Mostly Genetics, Not Gender
Eyelash length is genetically determined, just like hair color or height. If a man has long lashes, chances are someone in his family tree had them too. There’s no scientific rule saying men are supposed to have longer eyelashes than women—it just happens sometimes thanks to DNA.
The Testosterone Effect
That said, men do produce more testosterone, a hormone that influences hair growth. In some men, this can lead to thicker and darker facial hair, including eyebrows and even lashes. But this doesn’t apply to all men, and it doesn’t guarantee longer lashes either.
So while testosterone can sometimes play a small role, it’s not the main reason.
Makeup Makes a Difference
Here’s something we don’t always think about: women wear makeup, and men usually don’t. Mascara, eyeliner, and eye shadow can change the way lashes look. When you’re used to seeing lashes enhanced, natural ones—even longer ones on men—can stand out more by contrast.
That bare-faced look? It often makes a guy’s lashes seem more noticeable.
Is It an Illusion?
It’s also about facial features and contrast. Men tend to have thicker brows and darker lash lines, which can make their eyelashes pop—even if they’re not actually longer. Lighting, skin tone, and eye shape can all add to the illusion.
The Bottom Line
Men don’t biologically have longer eyelashes by default. If a guy has long lashes, it’s likely because of good genes, not gender. And the idea that men always have longer lashes? That’s just a common myth.
So next time you see a man with enviable lashes, you can thank his ancestors—not his testosterone.

Does crying make your eyelashes longer?
No, crying does not make your eyelashes grow longer. Tears can help clean your eyes, but they do not affect eyelash growth. Read full detailed article.
Can men have naturally long eyelashes?
Yes, men can have naturally long eyelashes. Eyelash length is mostly decided by genetics, so some men are simply born with longer lashes.
