Colour chameleon Kylie Jenner poses in a sultry sports bra throwback as she debates going back to brunette

From peach to platinum blonde and candyfloss pink to unicorn blue, Kylie Jenner has tried every hair colour imaginable.

But the Kardashian was contemplating a change to her faithful, natural shade on Monday as she told fans that she missed her brunette hair.

Kylie, who is currently enjoying a blonde phase, posted a sporty throwback of her dark hair look, asking for advice on whether to revert to her brunette roots.

Back to brunette? Kylie Jenner was contemplating a return to her brunette roots on Monday, as she shared a throwback photo

She wrote: 'I miss my dark hair should I go back?' as she shared a picture from her bathroom with her raven locks long around her shoulders.

One hour later, she shared a second as she ran her hands through her hair, appearing to have decided on the colour change.

Kylie reverted to the platinum hue again three weeks ago after running a rose gold wash through it. 

Should I? She asked her fans for advice on Instagram, and then shared a second picture an hour later as if she had decided to make the change

The reality TV star originally lightened her look eight weeks ago for her arrival in New York Fashion Week.

Naturally, it drew comparisons with her older half-sister Kim Kardashian who plumped for a shocking new platinum look for Paris Fashion Week in 2015. 

Though Kim was quick to ditch her blonde hair when she complained that it was falling out.

Kendall Jenner celebrated her 21st birthday this week and of course younger sister Kylie was there to help her celebrate.

The Kardashian clan and friends headed to Delilah in Los Angeles to party with Ken and Kylie certainly made an entrance.

The 19 year old wore rather racy attire, showing off her assets in a see-through mesh top and form-fitting leather trousers.

The trousers featured lace up front and side panels that exposed further skin and added a pair of sparkly heeled sandals to lengthen her pins. She was oozing serious sex appeal.

The leather trousers are by Unravel, a brand worn before by the likes of her sister Kim, Gigi Hadid and Alessandra Ambrosio, so Kylie is in good company!

Sadly the trousers are sold out, but click right to shop the brand's current line, or see below for lace up alternatives.

The original ash white dye job took three hours and she visited three more times in one week for touch ups, later calling it a 'full-time job'.

She temporarily went back to blonde in February 2016 but confirmed that it was only a wig. 

And while Kim is still keeping a low profile following her terrifying robbery in Paris last month, Kylie is moving ahead with her cosmetics business.
