10 Must-See Hair Transformations from Our Favorite Celebrity Guys

Every decade is defined by a few key hairstyles.

Men’s hair in the ‘90s was all about frosted tips and grungy, tousled ‘dos. Meanwhile, in the early 2000s, buzzcuts and shaggy styles became more popular. No matter the year, trending hair looks were often set by the A-list celebrities of the time. 

Who can forget David Beckham’s jaw-dropping shaved head from 2000? After years of rocking blonde tousled locks, his new hairstyle caused a buzzcut frenzy among young soccer fans in the U.K. Similarly, Justin Bieber’s trendsetting swoop hairstyle from 2009 was a major factor in “Bieber Fever,” and fans were devastated when he chopped it off a few years later.

In addition to iconic hair moments, celebs have developed signature hairstyles over the years. Lenny Kravitz has been known to sport long dreadlocks since the ’90s, while Keanu Reeves has maintained shoulder-length tresses for several years.

Ahead, take a look back at some of our favorite celebrity guys’ must-see hair transformations.

Travis Kelce

Travis Kelce is a fashion risk-taker who sports bold ensembles and ever-changing hairstyles (and facial hair!). At the beginning of his NFL career, Kelce favored a curly, coifed hairstyle with his trademark beard. He experimented with different variations of this ‘do before moving on to his current buzzed-about look, a fade haircut. Kelce has paired this style with every type of facial hair, from a mustache to a grown-out beard.

After a news outlet referred to his signature hairstyle as “The Travis Kelce” cut in early 2024, the football player set the record straight on the popular look. “Man, I got a good fade, if you need it. It’s a two on top, a nice high to mid fade with a taper on the back,” he said in an interview with ESPN. “But I didn’t invent that — I just asked for it.”

David Beckham

Beckham is a soccer legend and one of those rare people who can pull off nearly any hairstyle – and he’s tried many. During the early days of his soccer career, Beckham rocked a classic ‘90s hairstyle: long, highlighted locks that were slightly falling in his face. In 2000, the former soccer player shocked fans when he debuted a shaved head.

“I had a hairdresser at the time called Tyler. I said to him, ‘I’m gonna cut my hair’ and he was like, ‘Are you sure? You really want to do that?,’ ” Beckham said about the trendsetting cut in an episode of his 2023 Netflix docuseries Beckham. “I never did it to create attention. I’m not that person.”

Though he’s sported a buzzcut a few times since then, Beckham has also embraced a variety of other hairstyles. From long blond locks and a mohawk in the early 2000s to his signature soft, spiky style, he’s clearly a fan of constantly changing up his look.

Lenny Kravitz

Kravitz is the ultimate rock star, with the hair to match. Throughout the ‘90s, the “American Woman” singer was known to sport long dreadlocks. In the early 2000s, Kravitz chopped his hair into a short afro, which was displayed on his 2001 album cover for Lenny. Kravitz has experimented with several other hairstyles over the years, including cornrows and a shaved head, but has more recently returned to his signature dreadlocks.

During an interview with GQ in May 2018, Kravitz said that while it was “freeing” to cut his locs in the 2000s, he chooses hairstyles based on what feels right to him.

“It was very freeing, at that time. And I kept them off for a lot of years. And now I got ’em again,” he said. “It just kinda happened, and it felt like the right thing to let it grow. And it feels very correct right now. But at that time, it was a trip to be able to let that go and continue, without this thing that people identify you with. And it’s good to do that — challenge your own image and how people identify you.”

Harry Styles

Making the leap from boy band member to solo artist was more than just a change in music for Harry Styles. While the singer was known for his side-swept curls and later shoulder-length locks during his One Direction days, he opted for a completely new style at the start of his solo career.

In 2017, Styles displayed much shorter locks that were styled in a coiffed ‘do, which he had teased in an Instagram post the year before. Though he’s since developed a trademark mid-length wavy hairstyle, Styles switched it up once again in 2023 by opting for a buzzcut that shocked his fans.

“The fans are so passionate about his hair! At the beginning it made me nervous. Now, though, I get a lot of nice messages and it makes me so happy,” Ayae Yamamoto, Styles’ hairstylist, told PEOPLE in July 2023. “Every time they compliment Harry’s hair, it’s a compliment for me, and it makes me so happy, like, OK, I’m doing something right here. They’re such big fans and they know his hair so well, so I want to do right by them, because now I’m such a big Harry fan too.”

Brad Pitt

From a mullet to long blonde locks, there are not many hairstyles that Brad Pitt hasn’t tried. One of Pitt’s most popular styles was his buzzcut from 2004, a style he committed to for his role in Mr. and Mrs. Smith. Another iconic hair moment came a few years earlier when Pitt and then-girlfriend Gwenyth Paltrow sported matching haircuts at the 1997 premiere of The Devil’s Own. In 2021, the actress revealed that while their blonde pixie cuts were not planned, they did work with the same hairstylist, Chris McMillan.

Over the last few years, Pitt has largely maintained short hairstyles. He’s frequently seen with a long, coiffed ‘do but is also a fan of a tousled, spiky look that is reminiscent of his cuts from the late ‘90s.

Keanu Reeves

Reeves has a healthy head of black hair that he wore in a floppy, mid-length style for much of the late ‘80s and early ‘90s. In 1994, the actor debuted a buzzcut for his role in Speed. Reeves new ‘do reportedly shocked studio executives, who considered delaying filming so his hair could grow back.

For most of the early 2000s, the Matrix actor kept his hair short and tousled before he started growing it out. Reeves is now known for his signature shoulder-length locks with a center part that he rarely strays from.

The Weeknd

The Weeknd (né Abel Tesfaye) is known for his hits like “The Hills” and “Can’t Feel My Face,” but early in his career, the singer was just as synonymous with his go-to hairstyle. He wore dreadlocks that were tied up to create a structured ‘do, which made him instantly recognizable. Speaking with W Magazine in May 2023, The Weeknd shared that the recognizability was part of the reason why he decided to chop his hair in late 2016.

“The hair became an obstacle for me!” he told the outlet. “I went from ‘No one knows who I am’ to ‘Nobody has that hair except The Weeknd.’ I was always trying to hide it. When I finally decided to cut it, everybody said, ‘Don’t do it!’ That gave me more reasons to do it. I was so identified with that hair that I had to cut it. I didn’t want to be known for just this or just that.”

After cutting his hair, The Weeknd has worn a new hairstyle for each of his album eras. With 2016’s Starboy, he rocked a pompadour style, while an afro and a handlebar mustache characterized his After Hours era in 2020.

Jason Momoa

It’s hard to believe there was a time when Jason Momoa didn’t have his trademark shoulder-length curly locks, but he has sported a few other styles throughout his career. After getting his start as a model in 2000, Momoa opted for a short, coiffed hairstyle. The Aquaman actor then experimented with shaggy curls and dreadlocks before settling on his signature look.

In 2022, Momoa shaved off his hair while visiting Hawaii. In an Instagram video he shared of his haircut, the Hawaii native toasted to “new beginnings” and revealed he was cutting his locks to raise awareness about the use of single plastics.

Robert Pattinson

Robert Pattinson has been praised for his “chameleon” acting style, which has prompted quite a few of his hair changes. During his Twilight days, the actor was known for his messy, gravity-defying locks. In 2014, Pattinson debuted a shaved head for his role in The Rover and later sported a blonde, floppy hairstyle while filming the 2020 science-fiction film Tenet.

Though his bold haircuts don’t last much longer than the time it takes to make a movie, Pattinson isn’t afraid to go there for a role. During his off time, the actor mainly stays true to a short, tousled ‘do, but he did embrace a more slicked-back hairstyle for the Batman press tour in 2022.

Justin Bieber

When it comes to iconic hairstyles, the Bieber swoop might take the cake. The singer released his debut single, “One Time,” in 2009, which, coupled with his long, sight-blocking locks, was a recipe for superstardom. Following the success of his first album, My World, Bieber chopped his hair before embarking on a new era of music.

“We’ve been talking about it over the last six months or so,” his hairstylist at the time, Vanessa Price, told PEOPLE in 2011. “Cutting your hair is just part of the evolution and growing process for anyone, and I think he was just ready.”

Since then, Bieber hasn’t been afraid to experiment with his hair, sporting everything from a short, swept-up ‘do to platinum blonde locks. However, the singer has recently kept to two hairstyles, a buzzcut and messy, mid-length locks.
