The Duchess of Cambridge's shoulder-length style
Kate was as radiant as ever as she joined Prince William for the ICAP charity day, but it was her new hair length which also caught the attention of royal enthusiasts. The mother-of-two wore her glossy brunette tresses down, revealing she had a few inches chopped off leaving the length falling just below her shoulders, a contrast to her usually long tumbling locks.
Kim Kardashian going blonde
The Keeping up with the Kardashians star caused a social media frenzy when she stepped out for Paris Fashion Week having dyed her trademark dark tresses a shade of platinum blonde, slicked back for an edgy finish. Although Kim only rocked the look for a few weeks, it has since become one of her most iconic hairstyles to date.
The Duchess of Cambridge getting a fringe
In September, just a few months after welcoming Princess Charlotte into the world, Kate was spotted stepping out with a chic new fringe added to her sleek hairstyle. Heading to the Anna Freud centre in an elegant houndstooth ensemble, the Duchess showed off her new 'do by wearing her locks worn down in a sleek and chic style.
Princess Charlene of Monaco's pixie cut
The elegant royal showed off her beauty credentials when she had her short bob cut into a gorgeous striking pixie cut. "I knew that she wanted to do that, and I think she looks great with short hair," Prince Albert of Monaco told People.
Jennifer Lawrence's platinum blonde bob
Although Jennifer has rocked short hair in the past, she turned heads at the Hunger Games: Mockingjay Part 2 promo tour when she gave us all major hair envy as she showed off a new platinum bob hairstyle.
Emma Watson joining the bob brigade
The British actress turned heads as she arrived for a screening of documentary The True Cost in December, with her long brunette locks chopped into an effortlessly cool bob. While the star has rocked short hair in the past, recent years have seen her sticking to longer tresses, so this marked a fresh new look for the young star.
Adele's bob on The X Factor
After her incredible comeback earlier this year, Adele floored fans when she performed her hit song Hello during the X Factor final. However, it wasn’t just her vocals which impressed the crowds, as the singer debuted a brand new look on stage, having cut her hair into a smooth and straight blunt bob.
Lauren Conrad becoming a redhead
Lauren is renowned for her wavy blonde hair, so when she dyed her locks a bright auburn in December, it marked a whole new style for the star. We were huge fans of Lauren's makeover, which she admitted was inspired by her close friend and celebrity hairstylist Kristin Ess, whose hair is also a fiery shade of red.
Khloé Kardashian going for the chop
Khloé was renowned for her long tumbling tresses, so social media went into meltdown when it was revealed she had embraced the short hair trend and cut her locks into a long bob falling just above her shoulders. Since then the star has continued to wow with the edgy look, styling it into dramatic side partings for effortless glamour.
Gigi Hadid's faux bob
When Gigi arrived at the AMAs, it seemed that she had joined the bob brigade with her blonde locks worn slicked back in a bob style. However, it was later revealed that the young model had opted for a wig for the evening, her real hair tucked underneath to make for a natural finish.
Kylie Jenner's birthday makeover
As she celebrated her 18th birthday, Kylie ditched her long black tresses in favour of golden blonde hues. Although the star regularly tries different looks – including green and blue shades – we loved Kylie's bold makeover in honour of her milestone birthday.
