#30. Taylor Swift
Much like her critically acclaimed album, Taylor Swift has become fearless when it comes to her looks. However, it wasn't always like that. She rose to fame when she was still in high school, and for many years, she embraced her traditional country-girl style.
When Taylor cut and strengthened her hair, the fashion world was shocked. Not only that, but she started wearing what is now her signature red lipstick. It is now hard to imagine her without it!
#29. Mariah Carey
Mariah Carey released her first song when she was only 18 years old, and at that time of her life, she opted for a clean, innocent look with her natural corkscrew curls and clothes that weren't too revealing. After she divorced her ex, Tommy Mottola, there was a significant change in her.
She became much more confident and outspoken, and she started trying different styles, like smokey eyes, blond hair, and more. But after some time, she slowly toned it down, and found a middle ground between her first and her second style.
#28. Dove Cameron
DIsney Channel star Dove Cameron has changed a lot over the years. She was still in high school when her acting career began, and she opened up about how shy she was many times. It was hard to go to school because kids were mean, but she slowly gained confidence.
She used to wear very little makeup, and although she looked beautiful, nowadays she enhances her best features, turning heads wherever she goes. She now lines her lips, blushes her cheeks, highlights her cheekbones, and draws her eyebrows. All of this perfectly frames her face.
#27. Kendall Jenner
Kendall Jenner basically grew up in the spotlight. She first became known when she was just nine years old on Keeping Up With The Kardashians, and back in the day, she was a teenager with greasy hair just like all of us, but after puberty she became a model.
Modeling gave her the confidence she never had before,and she got the help and the resources from the best people in the fashion industry. Nowadays she makes sure her gorgeous eyes are the main center of attention, while she uses makeup to make her skin look soft.
#26. Cardi B
Cardi B's looks used to be very flashy and extravagant, and she used every color she could find on her face. While it didn't look bad, she didn't know at that time that less can sometimes mean more.
Nowadays, she tones it down much more when she is on the red carpet or at an event, and reserves the colorful outfits for the stage. She goes for nude lips with just some eyeliner to make her eyes stands out, which looks much more elegant and flattering on her.
#25. Kelly Osbourne
Kelly Osbourne has definitely had one of the best glow-ups of all time. When the world first got to know her, she was just the daughter of rock star Ozzy Osbourne, and her whole family appeared in their own reality show. She hated being on camera and felt very insecure.
She has opened up many times about her struggles with self-confidence, and it took her a long time to find herself. Slowly but surely, she left the heavy makeup behind and started trying things that brought out her natural beauty and made her feel confident.
#24. Christina Aguilera
Christina Aguilera has had some of the most iconic looks of this century, for better or for worse. She quickly started experimenting with everything from her hair, to her outfits, to her makeup, and of course, her music, and people were always wondering what she would do next.
In the late 2000s, Christina started toning it down and opting for a more pin-up look, like a modern version of Marilyn Monroe. The change was well received, and she kept it all through her Back to Basics album era. Nowadays, she enjoys nude colors, highlighting her gorgeous features.
#23. Avril Lavigne
In the early 2000s, people either wanted to be Avril Lavigne, or wanted to date her. She was the face of teen punk-rock and set the trends that everybody followed. She always wore her signature thick black eyeliner with no lipstick or anything else, and loved wearing dark baggy clothes.
She dyed her hair blond and her styled evolved into a Japanese-inspired look, which was also extremely popular at that time. Nowadays, however, Avril is in her 30s, and has chosen to tone it done and go for more age-appropriate looks that bring out her beauty.
#22. Victoria Beckham
Victoria Beckham has had one of the best evolutions in celebrity history. She was a member of the Spice Girls in the 1990s and reached worldwide fame because of that, and when the group split, she found her place in the fashion world.
Later in her life, she started going for a more polished, classic look that suited her much better. She stopped plucking her eyebrows thin and left dark lipsticks behind. Her subtle, clean makeup suits her much better and lets people focus more on her fashion, which is her main goal.
#21. Blake Lively
The world got to know Blake Lively as an adorable teenage actress. She has always been beautiful, but her early makeup choices weren't the best. Blue eyeliner with red lips was big in the early 2000s, but it just wasn't for everybody.
She now loves doing the "makeup that looks like you have no makeup" look, because it just shows how naturally gorgeous she is. She will use minimal eyeliner and only some lip gloss, unless she is attending a big event, where she will deliver a bolder look.
#20. Emma Watson
Emma Watson became world-famous when she was only ten years old as Hermione on the Harry Potter film franchise, so she grew up in the spotlight. Being under the media's scrutiny since a young age can make it hard for someone to feel comfortable in their own skin.
When the last Harry Potter movie came out in 2011, she chopped her hair short, which is something she could never do for her role as Hermione. It was a huge change and it marked the end of an era. If someone can rock short hair, it is definitely her.
#19. Drew Barrymore
Much like Emma Watson, Drew Barrymore grew up in front of the cameras. Back in the day, she was very young and ready to experiment with her looks, and that sometimes backfired. She used to use foundation that was too pale for her skin tone, coupled with dark lipstick that made her look like a vampire.
But taking risks comes with being young, and as she grew older, she truly found herself. Red has always been the hair color that best suits her, and she has kept it for many years now. She also goes for delicate makeup that makes her gorgeous eyes stand out, and the pale foundation is long gone.
#18. Courtney Love
Courtney Love was known in the 1990s as the grunge queen that would always surprise everyone with what she was doing. Her hair always looked messy and her red lipstick was a little much. Still, in the 2000s, Love went through several changes, most importantly, she pursued an acting career.
With her newfound passion came a new style, and it was breathtaking. She wiped her messy makeup off her face and replaced it with delicate, flattering makeup that was only there to complement her beauty. She also changed her hair and her overall style, and she looked like a completely different person.
#17. Kim Kardashian
Kim Kardashian has evolved in so many ways that it's hard to keep up with all of them. She started out as Paris Hilton's assistant and went on to become one of the most famous faces in the industry. She was also known as a party girl but now, she is a fashionista.
She stopped doing smokey eyes and went for a shimmery, bronze glow on her skin with only some lip gloss and fake eyelashes to flatter her face. Slowly, she became more and more interested in fashion, and even released her own clothing and beauty lines.
#16. Khloe Kardashian
Since we are on the topic, we have to talk about an even major glow-up that happened at the Kardashian home: Khloe Kardashian. A long time ago, Khloe was better known as Kim's younger sister, and people were really mean to her on the media and would usually call her "the ugly one", which destroyed her self esteem.
However, over time, Khloe picked herself up and decided to stop feeling sorry for herself. She became interested in fitness and fashion, dyed her hair blond, and started doing makeup that went better with her facial structure and skin tone. She looks like a completely different person now, but the biggest change is definitely her attitude.
#15. Bella Thorne
Bella Thorne used to be your typical innocent, sweet, low-profile Disney star. She seemed to have a promising career in her future, either in music or in acting. She went through a bit of a rough patch, but eventually came out on top.
It took her some time to find herself in that awkward time between being a teenager and becoming an adult, and it certainly wasn't easy for her. She did find her style, however, and we gotta say that it suits her perfectly. She loves using bright colors and lots of accessories, and she also changes her hair color quite often.
#14. Katy Perry
Katy Perry has reinvented herself so many times we've lost count. In 2004, she was fresh out of the Christian music world, and she would only out a little eyeshadow on and not go too crazy with her looks. When she became an international superstar, however, she was a completely different person.
In 2017, she went through a huge change again when she changed her signature black hair and not only dyed it blond, but also cut it short. She also went for very colorful, eccentric makeup and clothes, which made her look like a different person. Nowadays, she has toned it down, but kept her blond hair.
#13. Beyonce
Whatever Beyonce does, everyone wants to do. Ever since she rose to fame in the 1990s, she has been a beauty icon, and no matter what she did, she had everyone talking about it. Her early looks involved a lot of highlighting (before it was even cool!), with a lot of eyeliner and dark lip colors.
In the 2000s, she switched to a softer, more natural look that made her look much more youthful and classy. Nowadays, she uses much lighter foundation and matte lipsticks that make her look as if she weren't wearing any makeup. You can always expect Beyonce to follow the latest trends - or create them.
#12. Rihanna
When she started her career, Rihanna had a "good girl" image, but when she released her Good Girl Gone Bad album, she did just that. The title of the album reflected onto her image very clearly. From then on, she became a beauty and fashion icon, and whatever Rihanna did, everyone else wanted to copy.
One of her most iconic looks was her bright, red hair, which she flawlessly with red lips, and she kept for a good year. Nowadays, she goes for a more relaxed look, which makes it seem as though she isn't wearing any makeup, even though she totally is.
#11. Kylie Jenner
Kylie Jenner's glow up was subject to countless articles on the media and millions of comments on all her socials, and that's because she did a whole 360° with her looks. It is no secret that a lot of it has to do with surgery, which she has even admitted to, but it is definitely much more than that.
She went from being the smallest Kardashian sister to being a person of her own, and is now the youngest billionaire in the world thanks to her makeup empire. She did not only change her face, but she also changed her style, makeup, lifestyle, career, and most importantly, her attitude.
#10. Ariana Grande
Ariana Grande started out as a child star on Broadway and later on Nickelodeon. As she became a teenager, she dyed her hair hot red in order to stand out from the crowd, and it totally worked. She kept it for many years, until she went through another radical change: the ponytail.
Ariana is a person who, when she finds something that works for her, she sticks to it. Although many people wonder when she will let her hair down and try something knew, this is just part of her charm. Besides, thousands of young girls have also adopted her style. And when she decides to make a change, it'll sure be huge.
#9. Angelina Jolie
Angelina Jolie is undoubtedly one of the most gorgeous people on this planet, so it is very hard for her to do something wrong with her looks. However, it took her a few years to figure out what worked best for her. As the years went by, not only did she find her place in Hollywood, but also in her style.
In the 1990s, she went for the then-trendy blue eyeshadow and the cat eyes, which totally suited her. Nowadays, she uses very light foundation and always wears lipstick. One thing that has stayed constant all this time is her eyebrows, which always had the same perfect shape.
#8. Kristen Stewart
Before she became a bona fide star, Kristen Stewart was a blonde who didn't take many risks. Then, as her fame exploded in her Twilight days, she went for a more punk-rock look, with dark, wavy hair, and what would become her signature smokey eye. But, as the Twilight days came to an end, so did that phase of her style.
She moved on to a more classic, old-Hollywood style and even modeled for Chanel, with subtle eye makeup and dark red lips. She also cut her hair short, which made her gorgeous bone structure much more visible. This went on for a while, until she recovered some of her punk vibes and created a mixture of both of her styles.
#7. Jessica Chastain
Jessica Chastain didn't stand out from the crowd in her early days, probably because she wasn't as confident as she is today. She was shy, and her style also was. Flash-forward to a few years later, and she became a true Hollywood icon with a style to envy.
She straightened her hair and started wearing red lipstick, which goes fantastically well with her fair skin. She also made her hair slightly lighter, and even though her natural color is also gorgeous, there is something about her current color that just screams "star". She was always beautiful though!
#6. Pamela Anderson
Pamela Anderson has always been breathtakingly gorgeous because she was blessed with a perfectly symmetrical face and a golden smile. However, for many years, she decided to hide that under a ton of cakey makeup. She wasn't exactly famous for being a fashionista, but that has changed now.
In the 2000s, she started showing her natural beauty with very subtle makeup and minimal accessories, because when you look that good, you don't really need much to prove it. That eyeliner was really hiding her gorgeous features and making her look tired.
#5. Nicole "Snooki" Polizzi
Nicole Polizzi, also known as Snooki, became popular as the star of Jersey Shore, a reality about a group of party animals in the New Jersey coast that spent their time drinking, clubbing, and getting into trouble. It was her crazy personality that made people like her, but like all good things, it had to end at some point.
It was fun while it lasted, but when she got married and had a baby, Snookie decided to change her life. She left her party days behind, along with her spray tan, smokey eyes, and over-the-top hairstyles. She also got really into fitness, and now basically looks like a completely different person.
#4. Lady Gaga
If there is someone in this world who knows how to experiment with beauty, it's Lady Gaga. She has had so many makeovers that it's very hard to keep track, and that is what makes her so special. She has tried every rule in the book and has written many of her own. When her first single, Just Dance, hit the charts, she was all about the glitter.
Her style however, slowly morphed into eccentric, flashy, and sometimes even controversial. People either hated or loved her looks, but either way, everyone talked about her. That lasted for a good decade, until she decided to slow down. And while she still brings it every time, she would never be caught wearing a meat dress nowadays... would she?
#3. Bella Hadid
It sometimes seems like model Bella Hadid became famous overnight. In reality it wasn't quite like that, but her popularity did increase drastically in a matter of months. As soon as she started walking the catwalks, more and more designers wanted to book her, and in the blink of an eye, she was the most demanded model in the world. Oh, and also the highest paid.
When her mother, Yolanda Hadid, was on The Real Housewives, Bella tried as much as possible to stay away from the cameras and was very shy. But one day, something changed in her that made her the confident woman she is today. Every look she has is a success, and how could it not be with that face?
#2. Nicki Minaj
Rapper Nicki Minaj came into the scene in a similar way to Lady Gaga, only that she didn't go as far. She always wore colorful, extravagant wigs, coupled with very theatrical makeup that achieved her goal of getting everyone's attention, but didn't quite suit her. Then one day, she hit a switch, and became a completely different person.
Nicki then became all about glamour and embracing her natural beauty without covering it with bright colors and crazy wigs. Much like Beyonce, Nicki now thrives on looking effortlessly gorgeous, and looks even younger than she did with all the crazy colors.
#1. Miley Cyrus
There is a lot that can be said about Miley Cyrus and all the changes she went through. She started her career in Disney, where she became an instant superstar thanks to her show, Hannah Montana. As soon as the show ended, she started to try to find herself, and became wilder and wilder not only in terms of style but also her behavior.
This all came with her very short blond hair, clownish makeup, and eccentric outfits. She, however, shocked the world again in 2017 when she went back to her country roots, cleaned all the makeup and glitter off her face, and embraced her true self. it was incredible to see how much she changed, and she has never looked better.
