Elon Musk may have spent thousands on a physical overhaul to combat his hair loss and floppy skin, a plastic surgeon has claimed.

And he thinks the billionaire entrepreneur’s celeb beauty makeover was completed in the run-up to his October Twitter coup.

In an exclusive interview, Dr. Richard Westreich told The U.S. Sun: “I think Elon has taken care of his hair, his eyes and the hanging skin under his neck.

“Earlier this year, he looked odd, where you could see the type of swelling that you’d get after undergoing a neck lift.

“Since then he’s recovered, and doesn’t seem to have the strange fullness under his neck anymore.

“His possible neck lift could have cost up to around $60,000, but he may also have dabbled in under-eye filler, which would’ve been a fat transfer, costing around $10,000.

“Otherwise, the shape of Elon’s hairline looks to have changed at least four times over the years which would’ve cost around $40,000.”

Speculation about the Twitter owner’s altered looks has circulated for years and has been largely focused on his hair and jawline surgery, neither of which Elon has confirmed or denied.

And since the 51-year-old Tesla founder has an estimated net worth of around $164 billion, splashing out on plastic surgery or a slew of hair transplants would just be a drop in the ocean.

The neck lift he may have had is a procedure in which excess skin and fat are removed from the neck, leading to a smoother, slim profile.

It can be performed by itself or alongside fillers and even eye lifts.

“It usually involves an incision under the chin and then another incision around the ear and sometimes down in front of the hairline,” explains Westreich, who specializes in facial plastic surgery.

“Elon seemed to have gained a lot of weight around 2015 and then he started to lose it.

“Unfortunately, when aging is combined with this type of weight loss, the loose skin gets worse every year and creates skin laxity issues.

“With Elon the issue would be all the neck looseness he experienced.

“It makes sense that after losing that weight, he’d have some extra skin and he’d probably have wanted his jawline to look tighter.

“You can see where he’s wearing the black bow tie at the event with Kanye West in 2015 that he’s very heavy and has got quite a lot of fat under his chin.

But in photos from 2002, there appears to be “what almost looks like an incision around his earlobe.”

Dr Westreich said: “Here his face looks post-surgical to me.

“There’s also discoloration that looks like bruising and the very unusual swelling underneath his chin.

“You can also see an indent right behind his chin where there’s a little bit of extra hair.”

While Elon may have been busy tweaking his looks over the last few years, the noise surrounding his controversial Twitter takeover has intensified, with recent calls for the CEO to step down.

At the same time, the South African born tech star has gone on to become a paparazzi favorite while courting the media at some of the world’s most glamorous events, such as the Met Gala.

At the weekend, he was snapped enjoying the World Cup final in the VIP section at the Lusail Stadium in Qatar, alongside Jared Kushner.

“Another thing that can happen when you age and lose weight is the hollowness that’s under the eyes,” reveals Westreich.

“Elon was very hollow before.

“And he’s not hollow anymore so that’s either been dealt with using filler or transferring fat to his under eyes.

“I wouldn’t be surprised if there was little Botox in there as well.

“His hair also gets a bit shorter and seems to be growing in over time as over the years you can see that the hairline is starting to fill in.

“Usually the last thing that they fill in is going to be the shape at the front of the hairline which for Elon gets flatter and flatter.

“It looks very triangular in the beginning so they did the middle triangle, and then you can see that the triangle starts to flatten out over many years to what’s now almost a very flat hairline and all in one line.

“Generally with transplants, they fill in very slowly over many years, so he has probably had a couple of rounds.

“Sometimes they just can’t transplant everything in one session, but you can see with Elon that the shape of his front hairline has changed at least four times.

“I don’t think Elon has overdone anything and has altered things that are typical of a man who has become a celebrity.

“Elon is now in the public eye all the time.

“Some men don’t like the hanging skin underneath their necks anyway and if they wear ties and a collared shirt it drives them crazy.

“The youngest Elon looks though is in the photo where he’s wearing the black bow tie with Kanye West, but that’s when he’s overweight, unfortunately.”
