What does the makeup-loving Kylie wear when she can't be fussed to wear her extensions or call on her glam squad? According to one of her Instagram posts, she throws her mane up into a prettily disheveled top knot when she's feeling "too lazy to do [her] hair." But Kylie being Kylie, she still takes the time to execute a perfect cat eye -- and to smize for the camera. We'd happily take that off-duty look any day.

Kylie pulled her hair up to show off a multi-hued look that read business in the front, party in the back. Her playful peekaboo blonde stripe is further proof that the teen knows no limits when it comes to experimenting with hair color.

So long, sweet 16. Hello, sassy 17. Kylie celebrated her 17th birthday by shaving the back of her head and debuting a bold undercut that cements her status as a beauty risk taker.

Though teal became Kylie's go-to color, she kept things interesting during her blue period by switching up the length of her colored tresses. One day she might have a colored lob, while the next would see her with waist-length extensions.

In what can be considered an understated look for the envelope-pushing beauty maven, Kylie opted for neutral-toned eye makeup and lips, as well as a simple middle part that showed off her shiny locks.
