One of the latest hair trends to grace FYPs everywhere combines two of TikTok users' favorite things: the slicked back, model-off-duty bun, and Olaplex. TikTok users have been slathering their hair in the reparative goop, creating a bun, and then just going about their days as they normally would while the mask works its magic.

The hack is known as the "Olaplex bun," and TikTok users who have tried it out only have good things to say in their posts. The appeal is pretty obvious: The Olaplex bun allows you to deep condition your hair while sporting a trendy hairstyle that won't give you away in public.

The concept is certainly practical, but is this actually an effective way to deep condition your hair? As it turns out, gathering your hair into the bun might actually make the treatment work better compared to leaving your hair down. "The hair in the bun tends to be warmer and stays damp, says Nunzio Saviano, owner of the Nunzio Saviano Salon in New York. "The heat opens the cuticle of the damp hair, allowing the treatment to penetrate more deeply (into the cortex) and do its magic." (

To try out the Olaplex bun, you should first wash your hair as you normally would in the shower with shampoo to remove existing product buildup and dirt and oils, says Saviano. (That said, most TikTok users seem to use the method on second-day hair, misting their hair with a spray bottle of water rather than washing it to start.) Then, while hair is still damp, apply Olaplex to the ends, where you'd normally apply conditioner. Saviano recommends using Olaplex No.3 Hair Perfector (Buy It, $30, sephora.com), which is designed for deep conditioning. Some TikTok users have shared that they go with Olaplex No. 6 Bond Smoother (Buy It, $30, sephora.com), a frizz-fighting and strengthening styling treatment.

From there, you can leave the treatment on for as long as your heart desires. "It all depends on how dry or damaged your hair is," says Saviano. "I recommend [leaving it on] 20 minutes or so; it is sufficient for any hair to absorb the nutrients form a deep conditioner." However, he says you can leave it on throughout the day or even during a night out for a few hours. You can use the Olaplex Hair Perfector "as often as your hair needs — anywhere from doing it weekly to once a month," says Saviano. (

If you're after a Bella Hadid-inspired slicked bun, you'll want to follow a few expert tips. Add Olaplex No.3 from the mid-shaft to the ends on damp hair, says Saviano. Next, apply a very small amount of Olaplex Bonding Oil (Buy It, $30, sephora.com) to the rest of the hair, he says. You should then create a part with a comb, while smoothing the hair as close to the scalp as possible on either side. Twist the lengths of your hair into a low bun and secure it with bobby pins. You can leave two face-framing strands out of the bun if you wish. (

Whether you're more concerned with the appearance of your hair in public or with giving your treatment a bit of a boost, you can't go wrong with the Olaplex bun. TikTok, you're onto something.
