TikTokers are using a popular skincare product on their hair — and it seems to be working

A popular skin care ingredient has gone viral on TikTok thanks to its hair benefits. 

Beauty TikTok is ripe with quick fixes and hacks that sometimes work and sometimes flopNow people are singing the praises of using hyaluronic acid to restore their damaged hair. Our bodies naturally produce hyaluronic acid, a humectant that retains water. It’s typically found in the skin, connective tissue and eyes. Pretty much anywhere we want to stay lubricated and hydrated. 

Thus, the logic follows that if you’re trying to keep your hair hydrated adding the ingredient into your regimen may help. Luckily, if you feel like experimenting, hyaluronic acid is pretty affordable; there are the $15 drug store favorites by CeraVe and Neutrogena, plus the INKEY List has a $10 hyaluronic acid treatment specifically for hair.


Saw a TikTok that said hair oil doesn’t moisturize your hair, only water can. So I tried Hyaluronic Acid! 🤯 #hyaluronicacid #hair #hairhack #dryhair

TikToker Katilyn Boyer used The Ordinary’s $7 Hyaluronic Acid Serum and recorded her results. 

“I tried hyaluronic acid in my hair for two weeks and this is what happened,” Boyer wrote. “It feels so soft and is way more manageable.” 

The result spoke for itself. The ends of her hair went from looking a bit dehydrated to appearing sleek, shiny and healthy. 

Dermatologist Dr. Shah confirmed Boyer’s theory that hyaluronic acid can help the hair. 

“Hyaluronic acid is a powerful humectant meaning it holds over 1,000 times its weight in water. This hack is particularly good for people with dry or damaged hair, swimmers that are exposed to a lot of chlorine, people that use damaging shampoos and it’s safe for color-treated hair,” Dr. Shah said

TikToker @veexbby3 used hyaluronic acid on her bleached and dyed hair and it transformed in just seven days.
