Jenner turned to proChris Appleton, who also tookKim Kardashian Westicy blonde last year, to transform her look in honor of her birthday.

“Kylie is her own person — the whole idea — it’s not the predicted icy blonde. It’s a real transformation but it’s really golden. She likes to have fun with her hair. She’s been dark for a while, so it was time to change it up,” AppletontoldAllure.

“It’s beautiful golden fun,” Appleton says of the hue. “So many people stay away from gold. As a stylist, you’re taught that gold is hit and miss, but it’s really beautiful. It’s any girl’s dream,” he said.

It wasn’t a simple process to take Jenner from her deep brunette shade to such a light color. According to Appleton, he slowly transitioned the star to blonde over two full days of processing out of her own home.

“You’re pushing your hair to its limits. It can look really damaged. Hair has to be rich and healthy. It has to look like anewBarbie,” Appleton explained. “I take it very slowly and always do it over two days or longer. I gently lightened her hair in sessions — getting that right delicate gold is the hardest thing.”

Since one outfit wasn’t enough, the birthday girl stole the show in both a long sleeve, short magenta Dundas dress and later, a pink Swarovski-crystal covered LaBourjoisie jumpsuit which was made custom for the event and has a retail value of $8,000.

In her speech, the momager reminisced about watching Kylie grow up — giving a shout-out to her youngest child and Scott’s 6-month-old daughter, Stormi.
