A seismic shift has occurred. You might have felt it vibrating beneath your feet or in your bones. Even if you have no idea who Kylie Jenner is (which of course you do), you felt it in your gut. As of today, Jenner is no longer 18. She’s 19. You sensed it coming. Now it’s here finally, fully.

How do you celebrate when you’re the Snapchat celebrity that has everything? You could buy a new car, and also receive an additional car from your boyfriend Tyga. You could play with your new birthday puppy, a gift from a good pal. But those are really more of warm-up birthday activities. The real icing on the birthday cake if you’re Kylie Jenner, Lip Kit dealer, is hair. And so she changed it, donning a wig to ring in the last of her teen years.

The wig, which is by her guy Tokyo, according to his Instagram, is the color of primordial lava. It’s like the fires of Mordor or a color wheel gone nuclear. It’s also cornrowed, a style that’s gotten her in trouble before. But, like she told Marie Claire, last April, “I started wigs, and now everyone is wearing wigs. Kim [Kardashian] just used my wig guy last night . . . I just do whatever I want to do, and people will follow.” They grow up so fast and never fast enough, don’t they?
