While we don’t necessarily recommend digging up your old photos and making a trip down embarrassing hairstyle lane, take a look at how these celebs have transformed their style.

Julia Roberts
With a successful Hollywood career spanning more than three decades and a rare untarnished celebrity reputation, it’s hard not to adore America’s sweetheart. With the exception of her questionable taste in men over the years, we have to give it up to Julia for always making great choices, particularly when it comes to her style. She keeps it classy, simple and under control -- a lot like her life. Rules to live by, gals!

Lady Gaga
Whether she’s accessorizing with Pepsi cans and mosquito netting, twisting her locks up into a bow tie or rocking a sassy short look, Lady Gaga has our attention, and we can’t wait to see what she comes up with next. Edgy and resourceful, she’s in every gossip column under the sun thanks to her trend-busting style. Check out even more of her fabulous hairstyles here

Katherine Heigl
She’s been a blonde, a brunette and a redhead, and we hope that Katherine Heigl never makes up her mind. Whether it’s one of her retro styles or her classic girl-next-door looks, we can try these out on our own with the help of an anti-frizz cream to tame those wild curls and a shine polish to finish it off!

Rihanna
We don’t know how she does it, but somehow Rihanna pulls off that Skunky Brewster look. Her don’t-try-this-at-home hairstyles over the years have gone from long to short and blue to pink to purple and back again, but she’s always polished and true to her own style.
