When it comes to discovering new hair tips and tricks, TikTok is a goldmine. The TikTok hair community is always clueing us in on the most genius hacks. While some of them have been pretty questionable — like using perfume as hair dye — other hacks like the “bathrobe curls” trick and using rice water as a hair rinse have completely transformed the way consumers style and care for their hair.
At the moment, the latest hack to dominate “HairTok” involves adding one of skincare’s buzziest ingredients, hyaluronic acid, to your hair routine. Often hailed as a skincare hero for its moisturizing benefits, the miracle ingredient is being praised for its ability to hydrate and soften hair. In fact, hyaluronic acid has become so popular on the app that the hashtag #hylauronicacid has already garnered over 109.8 million views.
In a recent viral video titled, “I tried hyaluronic acid in my hair for two weeks and this is what happened,” TikToker Kaitlyn Boyer (@kaitlynroundtree) applies The Ordinary’s Hyaluronic Acid 2% Serum to her strands for two weeks, documenting the progress. After applying the serum to her strands every night, her once dry and brittle hair looks noticeably silkier, smoother, and more hydrated. By the end of the two weeks, viewers are able to see that Boyer’s locks are in a much healthier state and she even shares in the video that her hair is “so soft and way more manageable — even my hair stylist asked me what I’d been doing.”
While Boyer’s video certainly makes the case for adding hyaluronic acid to our hair routine, you might be wondering if it can really moisturize your strands. Dean Mraz Robinson, a Connecticut-based board certified dermatologist, told Allure, “Hyaluronic acid is a humectant, and rather than moisturizing hair, it works by drawing moisture in from the environment. When applied to damp hair, HA can hold approximately 1,000 times its weight in water.” It’s this moisture-binding element of hyaluronic acid that makes it so beneficial for most hair types as it not only soaks up moisture but retains it, keeping hair hydrated.
With the temperatures continuing to drop, now is a great time to consider adding hyaluronic acid to your hair routine, especially as your strands start to become more dehydrated and brittle. To help you out, we’ve rounded up a few of our favorite hair care products that contain hyaluronic acid.
