Our editors are always the first to hop on any beauty trend, especially when it comes to celebrity faves. There’s a rush of new products on the market, but the one
everyone’s talking about is K18’s easy leave-in treatment.
K18’s Leave-In Molecular Repair Hair Mask leverages biomimetic technology to reverse years of bleach + color, chemical service, and heat damage in only 4 minutes!
Powered by the patented K18PEPTIDE™, the mask reconnects broken disulfide bonds (what bond builders do) and broken keratin chains in the innermost layers of hair for renewed strength where it matters. Best part? K18’s biotech-powered treatment delivers lasting + progressive results with continued use. No wonder celebrity stylists can’t get enough!
Since K18 works on the molecular level (where all hair is the same), you don’t have to second guess if it’ll work for you. The full-size 50ml bottle has up to 50 uses, so this $75 treatment will last a long time.
Celebrity stylists are recommending this 4-minute hair mask not just to their celeb clients, but to anyone with colored or damaged hair wanting more #BestHairDays.
So, don’t just trust us–here’s what celebrities and stylists think about K18:
“It keeps Rihanna's hair strong and healthy over time and has really been working.”
- Yusef Williams, stylist for Rihanna
“Incorporating the hair mask into my morning beauty routine made me feel like a grown woman."
- Selena Gomez
“My hair was very damaged and my stylist recommended this leave-in repair mask – it literally brought my hair back to life.”
- Khloe Kardashian
“It delivers amino acids right to the center cortex of your hair, literally turning back the clock on damage. The more you use it, the healthier your hair gets.”
- Jacob Rozenberg, stylist for Irina Shayk and Karlie Kloss
“It strengthens hair, which helps to prevent split ends and breakage. My clients love that this makes their hair feel better than before it was ever colored.”
- Jeremy Tardo, stylist for Miley Cyrus, Miranda Kerr, and Florence and the Machine
“It sounds complicated, but you don’t need to understand it to see that your hair is back to being virgin again—before color and blow dryers wreaked havoc.”
- Alex Brown, Stylist for Kendall Jenner and Bella Hadid
See what we mean? It doesn’t take a celeb stylist to add K18 into your routine. Just shampoo, skip the conditioner, then add 1 pump of the K18 Mask to towel-dried, damp hair. Add more if needed and wait 4 minutes before combing + styling as usual–that’s it! Use this highly-concentrated leave-in for the first 4-6 washes, then switch to maintenance mode for a boost of strength, softness, smoothness, and bounce.
Bonus: K18 is also cruelty-free, vegan, and color-safe! A major win for any healthy haircare routine.
K18’s Leave-In Molecular Repair Hair Mask will keep your hair feeling and looking healthy from the inside out. Plus, the highly-concentrated formula means you need less to do more — so this tiny-but-mighty bottle goes a long way.
