You Need to See Blake Lively With Poison Ivy–Red Hair

If we asked you to name which celebrity has the best hair, we reckon Blake Lively would nearly always come out on top. Ever since the star got her break as Serena van der Woodsen in Gossip Girl, we've been obsessed with her blonde mane. True, she played a socialite in the TV show, which required her to have perfect-looking tresses, but in real life, the A-lister's hairstyles have also become some of the most covetable.

For example, type "Blake Lively hair" into Pinterest, and you'll discover that many of the looks have been repinned tens of thousands of times. And for good reason. Whether she's just out and about in New York or attending a film premiere, the star's hair is always in top condition. She'll try out new trends, such as the '80s curly hair look that's made a comeback, but she also pulls off the more classic Hollywood glamour styles. Oh, and she is not afraid of a hair accessory.

First up, we've got Lively's latest jaw-dropping hair transformation for her new movie, A Simple Favor. A few days ago, the actress deleted all of her Instagram posts as well as her profile picture and unfollowed everyone except for a few accounts by the name Emily Nelson, which is presumably her character's name in the movie. In the trailer, Lively's got her usual sandy blonde locks, but cut to 1:10, and she's got full-on Poison Ivy–red hair.

At the 61st Primetime Emmy Awards in 2009, Lively went for a messy plait in a ponytail. 

When she received the Breakthrough Performer of the Year award at the CinemaCon Awards in March 2011, the star wore a messy French twist.

Her first time experimenting with red, Lively surprised everyone by changing her trademark blonde locks and going strawberry at the Time 100 Gala in 2011.

A sleek ponytail was all Lively needed for this understated, glamorous look at the 2011 MTV Movie Awards.

This is probably one of our favorite-ever looks on the actress. The messy side plait complemented her white dress that she wore to the premiere of Green Lantern, again in 2011 (this was apparently a hallmark hair year for the actress).

Classic Hollywood curls were all the star needed to complete her look for the Age of Adaline premiere in 2015.

A sleek plait is always a great idea for a simple but elegant look. Lively wore this style to the Grace of Monaco premiere at the 67th annual Cannes Film Festival in 2014.

Not content with being the queen of incredible updos, Lively also knows how to wear her hair down in messy curls for red carpet events. Case in point: her look at the Mr. Turner premiere at Cannes in 2014.

Every once in a while, Lively will surprise us with a new hairstyle such as this low bun she wore to the Captives premiere at the 67th annual Cannes Film Festival in 2014.

This '60s Barbarella-esque look is everything. To re-create this style, all you need is to back-comb your crown to give the roots lift, spray some hair spray, and pop on a hairband.

The trick with this look is pulling the hair back and allowing tendrils to drop to frame the face. 

This ponytail is classic Lively, but the little kink in the back gives it a high-glamour twist.

The curly high ponytail from the back. To re-create this look, we suggest you create loose curls at the bottom of freshly blow-dried hair before tying it up. 

We know that the A-lister loves a high pony, but this version includes a tiny detail that we love—hair wrapped around the base of the ponytail. Lively wore this to the premiere of The Shallows.

This '80s hairstyle is making a comeback, and Lively is one of the first celebs to really tap into this trend. 

Perhaps one of the most popular hairstyles of all is this fishtail plait, which Lively wore to the premiere of her film Savages in 2012. Want to create your own version? Here's how to finally master the fishtail braid.
