Elon Musk’s ever-changing appearance has sparked endless speculation, from his slimmer frame to his seemingly fuller hair. Now, an AI-generated glimpse imagines what the tech mogul might look like without the rumored enhancements.

He’s conquered electric cars, space rockets, and social media with fearless swagger — but Elon Musk’s shocking physical transformation may be his boldest move yet. The balding PayPal nerd is long gone, replaced by a lean, chiseled mogul, allegedly sculpted by weight-loss drugs, anti-aging hacks — and a secretive hair transplant.

Doctor Sounds the Alarm After Musk’s Recent Appearance

Musk’s unexpected appearance on The Joe Rogan Experience in late October 2025 sent a ripple through the internet — and raised serious red flags for New York physician Dr. Stuart Fischer. While Musk’s voice remained steady, his face told a different story.

According to Fischer, the Tesla and SpaceX Chief Executive Officer (CEO) was exhibiting troubling signs of “rapid aging.” “Even at the Republican National Convention in July 2024, he was fresher-faced compared to now,” Fischer warned. “The exposure, the stress, and the controversy appear to have aged him physically and emotionally.”

Fischer, who has not personally treated Musk, made it clear: the transformation isn’t just skin-deep. “It puts you at risk of heart attacks and strokes,” he said grimly. According to him, constant stress floods the body with cortisol and adrenaline, fast-tracking cellular decline and making blood clots more likely.

Having chronic stress, he explained, wreaks havoc by limiting the body’s ability to absorb nutrients, reducing the effectiveness of antioxidants and vitamins, leaving cells rusted from the inside out.

Even worse? Diet and sleep — both easily sacrificed in high-stress environments — only accelerate the damage. That “rusting” isn’t just metaphorical; it’s visible. High cortisol levels actively break down collagen, robbing the skin of its firmness and glow.

The result? Saggy skin, dull tone, deepening wrinkles, and those dark under-eye circles we all dread. And it doesn’t stop at the mirror. Fischer warned that stress even warps brain function: extended cortisol surges can shrink the hippocampus, the part of the brain vital for memory, and fray the neural links responsible for focus and emotion.

The result is foggy thinking, poor recall, and emotional volatility, the very things critics say have increasingly defined Musk’s erratic public behavior. However, during his three-hour podcast appearance with Rogan, Musk showed no obvious signs of flagging energy, though his trademark awkward pauses appeared more strained.

Though Musk maintained his usual clipped delivery, something felt off, and Fischer wasn’t surprised. “It’s the stress. I don’t think he was ready for the overwhelming stress of winding up in the middle of international politics over the past few years,” he said. His verdict? The world’s richest man might also be one of its most emotionally drained.

Musk Jokes About Weight-Loss Medicines

But while Musk may look tired, there’s no denying he’s trimmer than ever, and he’s not exactly hiding the reason why. On December 26, 2024, he posted a shocking photo on X dressed as Santa Claus, revealing a svelte frame. The caption? “Ozempic Santa.”

In the comments, Musk clarified, with a laugh, “Technically, Mounjaro, but that doesn’t have the same ring to it.” He’s been openly vocal about the power of GLP-1 inhibitors like Ozempic and Mounjaro, praising them not just for slimming waistlines but for potentially transforming American healthcare altogether.

Earlier that same month, Musk slammed the US healthcare system while reposting Luigi Mangione’s viral manifesto on X. Mangione claimed that the US was the number one country with the most expensive healthcare system in the world, while ranked at number 42 for life expectancy.

“Nothing would do more to improve the health, lifespan [sic] and quality of life for Americans than making GLP inhibitors super low cost to the public,” Musk argued. “Nothing else is even close.” The message was clear: Musk sees these medicines not just as a personal tool, but as a national solution.

Intermittent Fasting and Heartburn

His transformation hasn’t come from substances alone. In a May 2020 appearance on Rogan’s podcast, the show’s host confessed he was dabbling in intermittent fasting. The host explained his daily 16-hour fast, which included only water or coffee during that window.

Rogan mentioned how he felt healthier when doing intermittent fasting, whereas he gained weight when he deviated from it. Musk agreed, noting that eating before bed triggered heartburn, which he said wrecks sleep quality and harms the digestive system.

The businessman shared that heartburn can damage the pyloric sphincter and the esophagus. When asked if he had time to exercise, Musk said, “A little bit.” He confessed that he hadn’t seen his trainer for a while and admitted that he doesn’t love running. Ever the reluctant gym-goer, Musk confessed:

“To be totally frank, I wouldn’t exercise at all if I could. I prefer not to exercise.”

Still, Musk conceded that if forced to choose, he’d opt for lifting weights or using a treadmill. When Rogan suggested martial arts, the CEO surprised him by rattling off a list of childhood training: taekwondo, karate, judo, Brazilian jiu jitsu, and kaika shrinkai.

Apparently, the conversation made an impression. Two years later, Musk tweeted, “On advice of a good friend, I’ve been fasting periodically & feel healthier.” The billionaire had taken the plunge, not just in business, but in body.

Hair Today, Gone Tomorrow – And Then Back Again?

Perhaps the most dramatic change of all is the one you see at first glance: Musk’s now thick, full hairline — a far cry from the stark bald patches he sported in his PayPal days. Dr. Jeffrey Epstein, a New York and Miami-based hair transplant expert (who has not treated Musk), was blunt, saying it’s “Highly, highly likely” he underwent a hair transplant surgery.

Epstein didn’t mince words, adding, “If you look at his pictures from his PayPal days, when he sold the company [in 2002], he was pretty bald.” The doctor continued, “I mean, he had a class three to a class four (out of seven) hair loss pattern [sic] and he now shows no evidence, at least in the front, of any hair loss.”

Back then, Musk’s scalp showed significant frontal thinning, known as “the Prince William look,” sparse baby hairs, and receded temples. According to Epstein, Musk was the perfect transplant candidate, blessed with healthy donor hair on the sides and back. Those are the follicles surgeons move forward to restore the hairline.

“It looks like he had good hair on the back and side of his head, and those are the hairs we use for transplanting,” Epstein explained. Though hair transplants have improved significantly in recent years, Musk likely received an older method that, while uncomfortable, offers impressive results.

Epstein said most patients can look presentable within a week, though the real results take up to six months. And the price tag? Staggering. A single session runs $8,000 to $15,000, and Epstein estimates Musk likely had at least two, totaling between $20,000 and $30,000.

“Offhand, you wouldn’t know that it was done,” he said. “But when you’re in the business, you know what to look for.”

Billionaire Makeover or Just Another Investment?

Whatever Musk has done, or spent, to achieve his striking transformation, it hasn’t hurt his finances. In fact, in November 2025, he edged closer to a historic milestone: becoming the world’s first-ever trillionaire.

On November 6, 2025, Tesla shareholders overwhelmingly approved a lucrative compensation package. Over 75 percent of votes cast favored the deal, excluding the 15 percent Musk already owns.

As the votes rolled in, the atmosphere inside the Tesla shareholder meeting turned electric. Cheers and chants erupted. Musk stood before the crowd and offered brief but heartfelt thanks. “I super appreciate it,” he said.

From struggling tech founder to potential trillionaire with a rejuvenated face and frame to match, Musk’s transformation is as baffling as it is brilliant, and the world, it seems, can’t look away.

Despite public scrutiny and speculation, Elon Musk remains unfazed as he continues to dominate both business and media landscapes. His evolving appearance seems to reflect the high-stakes world he thrives in.
