New celebrity hair hues! Jessie J takes to the dip dyed trend with red tips, Lauren Conrad tries out peach tresses and Kylie goes brunette

Jessie J is now cast free and to celebrate she's matched her fierce personality with flame-hued hair, and we like it!

The singer arrived at Birmingham Ormiston Academy today sporting longer locks (thank you hair extensions) working the dip dyed look with pillar-box red ends.

It definitely has impact as the colour works well against her jet-black hair. She continued the feisty theme in leather-look leggings, red suede lace ups and an animal print crop top.

But she's not the only celebrity to be changing her hair colour…

Celebrity pro Kylie, knows that the art of staying in the showbiz game is reinvention and what better way to stay in the spotlight than to reach for the (dye) bottle.

We nearly pulled our clip-in hair extensions out as pictures surfaced of the formerly iconic blonde Kylie with warm brunette locks — we're still in shock!

But the Australian singer's hair isn't the only barnet to hit headlines, Lauren Conrad has taken the dipped dye trend to a new level with peach accents on the ends of her strands.

Kylie's new hair colour got the attention it deserved as she filmed her latest advert for Lexus yesterday; her tresses had been teased into a low beehive with short, shoulder-height curls cascading down her neck.

She originally went to the dark side when she received her Honorary degree from Anglia Ruskin University earlier this month. Was this a move to fight off any 'dumb blonde' stereotyping or a bid to bag a hot new man?

Lauren didn't do as drastic a hair do as Kylie, but has still made waves with her new peach hair! While Katy Perry pulls off light pink hair with aplomb, Lauren worked the pastel trend her way.

The reality-star-turned-designer debuted new tress tips yesterday with a peach colour complementing her bright blonde hair.

Lauren went for the very light shade of pink after asking the readers of her website which colour they'd like. A staggering 73% of people voted for peach.

We love this playful way to update long-hair styles, we'll be dying those hair extensions tonight…
