Kylie Jenner documents her hair transition on Snapchat.

Not content with her silky raven locks, the baby of the family, Kylie Jenner, has copied her big sister Kim Kardashian and dyed her hair a startling shade of platinum blonde.

The 19-year-old stunner debuted her hot new look on a night out with friends in the Big Apple before heading to Kanye West’s concert at Madison Square Garden.

Jenner was making sure she stood out from the crowd as she dined at Nobu, opting for a sexy red bustier paired with a red leather mini skirt.

She completed the look with a matching red leather coat, an interesting choice considering New York’s humid weather.

She was joined by sister Kendall and pal Hailey Baldwin.

Though Jenner seems pleased with the final product, this isn’t the first time her hair has undergone a dramatic transformation. She transitioned from brunette to dirty blonde last autumn.

“Took months of not dying my hair and wearing wigs to get my hair back to health so I can do this,” she wrote on Instagram. “I’m going for an ashy dirty blonde for the fall.”
