Should You Grow a Mustache? What Research, Real Feedback, and the 2026 Thin Mustache Trend Say Before Movember

Should you grow a mustache, or does it make you look worse? For most men, the honest answer is that a mustache alone is a harder look to pull off than stubble or a short beard. But the mustache is having a real moment in fall 2026, Movember starts November 1, and for some faces it works very well. Here is what research says about facial hair and looks, why the thin mustache is trending, what happens when men post their mustache online for feedback, and how to tell if it suits you.

What the research says about facial hair and attractiveness

There is a lot of research on beards and stubble, and much less on the mustache by itself. Here is what holds up.

Stubble wins with women. A 2008 study had 60 women rate the same faces with five levels of facial hair. Light stubble scored as most attractive and was preferred for both short and long term relationships. Full beards scored as most masculine, older, and more aggressive, but least attractive.
Heavy stubble wins in the biggest study. A 2016 study with 8,520 women found heavy stubble got the highest ratings for attractiveness, then full beards and light stubble, with clean shaven faces last. Beards helped more for long term relationship ratings than for short term ones.
Women prefer less facial hair in two countries. A 2020 study in the US and India found more facial hair made men look older, stronger, and more assertive, but less friendly. Women in both samples preferred less facial hair.
Bosses prefer clean shaven. A 2003 study that tested clean shaven, mustache, goatee, and beard versions of the same man found hiring managers clearly preferred the clean shaven version over all three facial hair styles.

The short version: no study crowns the mustache. Stubble beats it for looks, and clean shaven beats it for first impressions at work.

The lesser-known part: rarity makes it work

This is the most useful finding for anyone thinking about a mustache.

Rare looks get a boost. A 2014 study showed people faces where beards were either rare or common. Beards were rated more attractive when they were rare, and clean shaven faces were rated less attractive when everyone was clean shaven. In plain words, standing out helps.
Mustache fashion follows the dating market. A 2001 study of British history found mustaches and beards became more popular when there were more single men than women competing for partners. The author's idea was that men lean into showy, manly looks when competition is tough.

So part of why the mustache is back may be simple. After years of everyone having the same stubble or beard, a mustache stands out. That works for you only if it also fits your face.

Why the thin mustache is trending now (October 2026)

Celebrities. The Guardian reported on Oct. 16, 2026 that Carlos Alcaraz played the Shanghai Masters with a mustache after his team agreed to grow them if he won the Japan Open. It also named Jacob Elordi, Harry Styles, Timothée Chalamet, and Ncuti Gatwa as recent mustache wearers.
Barbers see it. UK barbers told the Guardian that more young men are asking for mustaches, and many want thin ones. One called the thin style "low maintenance" and "attainable to most." Another said the move is away from heavy 1970s and 1980s styles toward a "refined, deliberately styled look."
Thin over thick. A Times Now piece on Oct. 21, 2026 called the thin mustache the "skinny upgrade" of the thick 1970s style, worn more like an accent than the main feature of the face.
Movember. Movember's 2026 campaign, announced Oct. 9, asks men to make a public "Growmitment" with a friend to grow a mustache or take part another way, and runs through Nov. 30.

A scholar quoted by the Guardian made an edgy point worth thinking about. She said thin mustaches may be a way for young men to look grown up and manly without signaling "alpha" manosphere style masculinity.

What people say when men post their mustache online

Late October 2026 brought a wave of "mustache or shaved?" posts, likely with Movember coming. Here is the pattern in the replies.

Most votes go to shaved. In one late October post, a man who had grown a mustache for a month asked if he should shave it. The replies were nearly all "shaved." Several said he looked like Mario, one said the mustache got in the way of his "great smile," and one said it looked good only "if you can grow a big one." He shaved it and said he thought he looked much better.
It pulls focus. In another post, one reply said a mustache "takes attention away from your face as a whole," and that very few people can pull off a thick, wide one.
Most men trim too early. One reply said the real problem was trimming the mustache before it was ready to style. A thin or patchy start looks like a mistake, not a choice.
A beard can balance it. A man with a beard for 15 years asked if he should switch to just a mustache. Replies leaned toward the beard because it "balances his features," and one woman said "we women love a bit of grey."
Some styles carry baggage. In late October one man posted that someone told him his mustache made him look like Hitler. Short, square styles that sit only under the nose carry that risk.
Not everyone can grow one. Posts like "been trying to grow my mustache for 2 years" are common. Patchy or light upper lip hair is normal, and no grooming trick fixes thin genetics fast.

The edgy truth here: a mustache is a style choice that strangers judge hard and fast. Online feedback is brutal and leans toward safe looks, so take it as a strict test, not a final verdict. But if almost everyone says "shave it," believe them.

Who a mustache tends to suit

Men with thick, even upper lip hair that connects at the corners.
Men with a wider upper lip area, where a mustache fills space rather than crowding the mouth.
Men whose style already leans vintage, artsy, or fashion forward, so the mustache looks planned.
Men in their late 20s and up, or younger men who want to look a bit older.

It tends to struggle on men with patchy or very light hair, a very small mouth or upper lip, or a round baby face, where it can look like a costume.

Lesser-known tips

Give it four weeks before you judge it. The first two weeks almost always look bad. That is why Movember runs a full month.
Thin and tidy beats thick and messy. The trend is a clean line, trimmed so it does not cover the top lip. A thick style needs real density to work.
Test it with a beard first. Grow a short beard, then shave the cheeks and chin and keep the mustache. You get to see the mustache at full size on day one instead of waiting.
Take photos, not mirror checks. You see your mirror image every day and get used to it. Photos show you how others see the change.
Change one thing at a time. Many of the worst rated posts paired a new mustache with a hat or a bold outfit. Judge the mustache with your normal look.

Bottom line

The research does not back the mustache as a looks upgrade for most men. Stubble or a short beard scores better, and clean shaven looks safer at work. But rarity has real pull, the thin mustache is genuinely trending, and on the right face it adds character. If you have the hair for it, Movember is a free, low risk month to try. If you would rather know before you commit, The Face They See lets people of the opposite gender rank your photos for free, so you can compare a mustache shot with your clean shaven or stubble photos.
