The 3 Trending TikTok Hair Secrets You Need to Know

It's official: TikTok is the harbinger of trends. Before you’ll see a beauty secret pop up on Instagram, YouTube, or Pinterest, it will be making the rounds via 15-second clips to a catchy track on “the clock app.” But if the algorithm isn’t tuned to your liking yet and you’re missing out on the latest “it” thing because of it, worry not! We’ve got you covered, with three trending TikTok hair secrets you’ll want to explore for yourself.

1. Hair Slugging is the Latest Obsession

Although, it isn’t a new concept. On TikTok, the idea stemmed from the recent conversation around slugging your face overnight. Historically a Korean skincare practice, slugging involves slathering one’s face with a moisturizing occlusive before bed. Whether you use Aquaphor, CeraVe, or Vaseline (three of the most popular picks), it helps to lock in the other nighttime skincare products you applied. In theory, it makes them all more effective.

Enter, hair slugging. We’ve all seen the incredible results face slugging can have, so it’s little wonder TikTok has quickly evolved the practice to accommodate hair. But while it’s trending now because of traction on the app, #hairslugging isn’t anything new.

It might not have been called slugging before, but the concept of using a generous amount of oils and other hydrating products before bed is one that goes way back. The practice has been a part of Black beauty culture, as well as that of Asian and Caribbean communities, for generations.
Apply a leave-in conditioner or oil in larger-than-usual amounts and bundle your hair up into a wrap or scarf. You’ll wake to less frizz and more shine. Yes, please!

2. From Kitchen to Beauty Cabinet: Rosemary Oil

Fittingly, this could work together with slugging. Rosemary oil is a beautiful thing for more than just its delicious flavoring. TikTok creators like Taylor Rose of @thehealthyhygge have started a movement of video love for rosemary oil. And with result videos showcasing thicker, more luscious locks, who wouldn’t jump on the bandwagon?

But why does rosemary oil benefit hair? Let’s turn to the science.
Marnie Nussbaum, MD, FAAD, board-certified dermatologist, sat down with Elle to give them the scoop. Her insight? “The rosemary plant contains carnosic acid which is known to heal nerve damage, tissue damage, and improve cellular turnover. Therefore, it encourages nerve growth and improves blood circulation. The reason blood circulation is so important to hair growth is that without a proper blood supply, the follicles do not get the nutrients they need to grow the hair and they can die off.”

Quick relevant aside: This is why our DeeplyRooted supplement has CococinTM Coconut Water, Resvenox® Resveratrol, and Bioperine®—all ingredients that support circulation.

But back to rosemary! It’s also a great pick because it can be used on any hair type. Since it is working with the follicle, not the strand, it won’t have an unwanted effect on, let’s say, color-treated hair. That said, as Nussbaum later notes in the same article, there isn’t much data on use while pregnant or breastfeeding, so mamas, tread lightly!

3. Heatless Curls Are the Trending TikTok Hair Secret for Euphoria Fans

If you can’t get enough of the internet’s latest episodic obsession, this one’s for you. In the now-famous scene where Cassie goes about her therapeutic 4 a.m. beauty routine, she uses a heatless curling rod headband. While it’s in, she goes through her skincare and self-tan rituals, and by the time she pulls them out, a near-perfect blowout look awaits.

It almost seems too good to be true, right? Well, TikTok has done the vetting for you and the answer is apparently no. Spend some time browsing #heatlesscurlingrodheadband and the magic becomes evident. If you have an extra hour or two to spare (or better yet, overnight), this is a way to get gorgeous curls with zero heat damage.
