Let’s be honest, we’ve all seen the photos. One minute Conor McGregor is headlining a UFC press conference with a hairline that looks like it’s retreating faster than a defeated opponent, and the next, he’s posting Instagram selfies with a thick, straight-as-an-arrow mane. It’s the kind of transformation that doesn’t just happen because you started using a better shampoo or "ate your greens."
The Conor McGregor hair transplant rumors didn't start in a vacuum. They started because, for a man who obsesses over his image as much as his left hook, the shift was impossible to ignore.
But did he actually get it done?
While the "Notorious" one hasn't exactly sat down for a Vogue interview to discuss follicular unit extraction, the visual evidence is screaming. Most hair restoration experts who spend their days squinting at scalp photos for a living seem to agree: something surgical went down, likely around late 2021.
The Smoking Gun: A Timeline of the McGregor Hairline
If you look back at 2013, Conor had what doctors call a "mature" hairline. It was fine. Standard. But by the time he was facing off against Dustin Poirier for the third time in 2021, the temples were noticeably deep. He was hitting a solid Norwood 3 on the balding scale.

Then came the leg break.
The injury that sidelined his fighting career for years actually gave him the perfect "down time" for a transplant. You can't exactly take a head-kick three weeks after getting 2,000 grafts poked into your scalp. During that hiatus, Conor was spotted with a buzzed head and—interestingly—some tell-tale scabbing and redness along the frontal line.
- 2014-2016: Classic recession at the temples. He hid it well with that signature slicked-back style and a heavy dose of hair product.
- 2020: The thinning was becoming undeniable, even with the best barbers in the world trying to "mask" the corners.
- Late 2021/Early 2022: The "Reset." He shaves his head. Suddenly, when the hair grows back, the hairline isn't just fuller—it’s lower. And straighter.
Basically, hairlines don't just move forward on their own as you hit your mid-30s. Biology usually works the other way.
Why Some Experts Think the Conor McGregor Hair Transplant "Failed"
Here’s where it gets kinda messy. If you look at photos from 2024 and 2025, some of that initial "super-density" seems to have faded. This has led to a lot of chatter in the hair restoration community about whether the procedure was actually a success.

There’s a theory that the surgeon might have harvested hair from the "unsafe" zone. In a standard FUE (Follicular Unit Extraction), you take hair from the back of the head because those follicles are resistant to DHT—the hormone that causes balding. If a surgeon gets greedy and harvests from areas that are actually also destined to fall out, the "new" hair will eventually thin just like the old stuff.
Also, let's talk about the design.
A lot of critics point out that Conor’s new hairline was almost too straight. Natural hairlines usually have a bit of irregularity. When you see a 35-year-old man with a hairline that looks like it was drawn on with a ruler and a Sharpie, it’s a dead giveaway. Recently, it looks like he might be experiencing some "shock loss" or continued thinning behind the transplanted area, which happens if you don't stay on top of maintenance meds like Finasteride or Minoxidil.
The Technical Stuff: FUE vs. FUT
Most people assume he went with FUE.

Why? Because Conor loves a fade. If he had gone with the older FUT (strip) method, he’d have a long, linear scar running across the back of his head. We’ve seen him with a grade-zero buzz cut plenty of times since the rumored surgery, and there’s no visible strip scar.
FUE is the "gold standard" for guys like him. It’s less invasive, the recovery is quicker, and it allows for that precise "individual follicle" placement. It's estimated he probably had anywhere from 1,500 to 2,500 grafts.
What This Means for Your Own Hair Journey
Honestly, seeing a guy with McGregor’s resources go through the ups and downs of hair loss is weirdly reassuring. It shows that even with all the money in the world, you can't completely outrun genetics without a plan.
If you're looking at Conor and thinking about pulling the trigger on your own procedure, here are the real-world takeaways:
- Timing is everything. Conor likely used his injury layoff to heal. You need at least 10–14 days where you aren't doing anything strenuous. No sweat, no hats, no contact.
- Don't skip the "maintenance." A transplant doesn't stop your original hair from falling out. If you get the front fixed but don't use preventative treatments, you’ll end up with a "tuft" of hair at the front and a desert behind it.
- Age matters. Getting a "teenager hairline" when you're 36 can look a bit "uncanny valley." Most reputable surgeons recommend a slightly more recessed, natural look that ages gracefully.
- The "Second Pass." Don't be surprised if one surgery isn't enough. Many celebrities (and regular guys) end up needing a second "touch-up" procedure a few years later to add density.
Conor McGregor hasn't officially joined the ranks of celebrities like Wayne Rooney who are open about their transplants, but the mirror doesn't lie. Whether it was a "perfect" success or a bit of a mixed bag, his hair evolution is a masterclass in how modern aesthetics can change a man's entire "vibe."
If you’re noticing your own temples heading for the exit, your first step isn't booking a flight to Turkey. It’s talking to a dermatologist or a hair specialist about stabilizing what you’ve already got. Most people find that starting Finasteride or Minoxidil early can save them from needing a 2,000-graft surgery down the road. Focus on the "donor area" health first, because once that hair is gone, you can't get it back—even if you're the highest-paid fighter on the planet.
