Here’s a flashback of 2013’s most attention-grabbing hairstyles, haircuts and hair colours spotted on the celebrities on the red carpets and via social media.

On the Edge

Dubbed the “undercut,” celebs, including Rosario Dawson and Rihanna, were seen sporting long locks on one side of their head along with a close shave on the other, putting a new twist on short coifs.

Chop Shop

Not too long, not too short, but just right. As winter turned to spring, hairstyles were all about finding a fine balance between the extremes. From runways to red carpet events, supermodels and stars like Karlie Kloss and January Jones rocked fresh, mid-length styles.

Making It Social

Whether they were getting new haircuts or changing hair hues, nearly everyone went to great lengths in sharing their salon experience. Twitter and Instagram were the most popular social media tools of choice among celebs, including Beyoncé and Coco Rocha, who shared their transformations with their respective legions of followers.

Over the Rainbow

Between brilliant emeralds and subtle violets, when it came to hair colour, it seemed that rainbow hues were all the rage. Young starlets including Madonna’s daughter Lourdes Leon went green while even more mature women like Dame Helen Mirren debuted her pink coif at this year’s British Academy of Film and Television Arts Awards.

Paying the Price

In the world of the rich and famous, some celebs will spare no expense for their hair, and perhaps no stylist understands this better than Ted Gibson, who raised his prices for a haircut from $950 to $1,200. Upping the ante even further, Reese Witherspoon reportedly spent $1,500 for a branded haircut that is said to achieve the most natural look by treating every hair strand individually.

Royal Tresses

Continuing her reign as “The Most Iconic Hair of 2013,” the Duchess of Cambridge ruled supreme as we pined for her stylists’ coveted secrets for achieving her lustrous locks. Perhaps her signature style is not only a result of exceptional salon treatments, but also a shining perk of her highly-publicized pregnancy. See a slideshow of her best hair looks here.

And the Award for Most Controversial…

When it comes to making waves in 2013, no one does it better than Miley Cyrus. And that’s just with her hair. From long and ombre to chopped and bleached out, it’s been a total image makeover. On the hairstyle front, you can’t help but be impressed with the chances she’s been willing to take. We’ll skip over her performances.
