This TikTok Viral Hair Mask Is Hailey Bieber Approved


If you’ve been scrolling through TikTok lately, chances are good that you’ve seen the K18 Leave-In Repair Hair Mask making waves. This innovative hair treatment has captured the attention of beauty enthusiasts and celebrities alike, including Hailey Bieber, who swears by its transformative effects. 

Without a doubt, the K18 Leave-In Repair Hair Mask has become a serious game-changer in the world of hair care. It promises to restore and rejuvenate even the most damaged locks leaving your hair looking fantastic and feeling silky. 

The Power of K18 Leave-In Repair Hair Mask

What sets the K18 Leave-In Repair Hair Mask apart from other hair treatments is its groundbreaking K18 Biomimetic Hairscience technology. Unlike traditional conditioners and masks that only provide surface-level hydration, the K18 formula works at a molecular level to repair keratin chains within the hair. 

The product’s dramatic hair repair capabilities result in stronger, healthier hair that can withstand daily styling and environmental stressors with ease. 

To use the K18 Leave-In Repair Hair Mask:

  • Apply to towel-dried hair
  • Leave it in for four minutes
  • Style as usual

There’s no need to rinse the formula out, making it a convenient addition to any haircare routine. 

Users report that their hair feels softer and shinier. Many also believe their hair is more manageable after just one use.

  • The K18PEPTIDE™ is a peptide developed through biotechnology that mimics the natural structure of hair. It works to repair damage by reconnecting polypeptide chains and disulfide bonds that are often broken during processes like bleaching, coloring, chemical treatments, and heat styling.
  • Its pH range of 5.0-6.0 helps reduce cuticle swelling and optimizes the hair proteins to be in their most resilient state after salon treatments or shampooing.
  • The cream formula allows for easy and lightweight application on all hair types, providing benefits such as detangling and softening.

The Ultimate K18 Mask Guide: Dos and Don’ts


  • Clarify First: If you’re a heavy product user, start with a demineralizing treatment to remove mineral and metal buildup.
  • Apply on Clean, Damp Hair: For best results, make sure your hair is freshly washed and towel-dried.
  • Patience is Key: Wait 4 minutes before combing or styling to let the mask work its magic.
  • Style Away: After the 4-minute wait, feel free to apply your favorite styling products.


  • Skip the Conditioner: Don’t use the conditioner before applying the K18 mask. You can use it after the 4 minutes if needed, but most find it unnecessary.
  • Less is More: Don’t overdo it with the mask. A little goes a long way.
  • No Rinsing: Do not rinse out the mask—let it stay in and continue to repair your hair throughout the day.

Follow these tips to get the most out of your K18 hair treatment and enjoy luscious, healthy hair!
