TikTokers Like Charli & Addison Are Hopping On This "Deja Vu"-Inspired Challenge

When you do the "deja vu" challenge, you need to keep tapping your screen to switch back and forth between the inverted image. Since it works best with your face at the center, some people like to set their phones up on a tripod or sturdy surface. But if you're as coordinated as Charli D'Amelio (@charlidamelio), have fun with your challenge by moving your camera in and out while also getting animated with your face.

If you're doing the challenge alone, you really want to center your face for the inverted effect. It creates the déjà vu feeling as you switch back and forth. TikToker @jikanibruh really nailed this, but according to the caption, it took five minutes to set up. So, be patient with yourself.

TikToker @yeahimcaroline has red and black hair, so this challenge looked super cool switching back and forth. If you also have different-colored hair, you'll want to try it out to see your colors change. Even if you don't have two-toned hair, wear your hair in pigtails like Caroline and use different colored scrunchies to see them flip back and forth. Or, you could try two different makeup looks. It's all about playing with the symmetry.

Some TikTokers aim for perfect symmetry in their "deja vu" challenges. But if you're looking for that flip, try doing a one-sided hairstyle like TikToker @havoshouse. Something as simple as a side ponytail will look really cool in your video.

The "deja vu" challenge can be done solo or with your friends. For instance, Addison Rae (@addisonrae) did it with Dixie D'Amelio. Normally, these two TikTokers don't look alike, but by the end, they could be twins. Try this challenge with your bestie, and people will start thinking you're related.

Speaking of twins, the Mian twins (@miantwins) "had to hop on this trend" as well. Since they are twins, Azra and Aisha already look alike. But since their head movements are also so in sync in the video, it adds an extra bit of déjà vu to the mix.

If people tend to think you and your BFF look like twins, you've got to try the "deja vu" challenge. Dancer and actress Maddie Ziegler (@maddieziegler) did it with her "twin for life" — Alexis Ren. Unlike other TikTokers, they didn't stare straight into camera, but they did wear matching outfits and a bold red lip.

You don't have to stop at two people either. TikToker Munera (@iconiccpinkk) did this trend with her sisters. As long as you keep a symmetrical formation, you can do it with as many people as you'd like.
