K18 Molecular Repair Hair Oil delivers a weightless finish that helps smooth frizz and adds high gloss shine without making hair feel heavy. Designed for all hair types, this lightweight oil blends conditioning oils with modern emollients to leave strands softer, sleeker, and easier to style. It helps support a stronger feeling look and improves the look of split ends, while keeping flyaways in check for a polished result. The formula also helps shield hair during heat styling up to 450°F, making it a smart step for daily styling or finish work.

Benefits:

  • Helps smooth frizz and tame flyaways for a sleek, polished finish
  • Helps hair feel stronger while improving softness and manageability
  • Helps enhance shine and support brighter looking color vibrancy
  • Helps protect hair during heat styling up to 450°F

How to Use:

  1. Start with clean, towel dried hair or dry hair for finishing.
  2. Warm 1 to 3 drops between palms, then smooth through mid lengths and ends.
  3. Add more as needed for thicker hair, then style as desired. Use before heat tools and as a finishing step to smooth flyaways.

Key Ingredients:

  • K18Peptide: A patented sequence of amino acids that helps hair feel stronger and look smoother for a more resilient, polished finish.
  • Squalane and Hemisqualane: Lightweight smoothing emollients that help soften hair, improve slip, enhance shine, and reduce the look of frizz and flyaways without a greasy feel.
  • Avocado Oil: A nourishing oil that helps condition dry feeling strands and supports a softer, more flexible look.

Black but don’t worry it is supposed to be. It works!
Size: 1 Liter
This stuff looks like used motor oil but don’t worry that is the molybdenum disulfide (MoS₂) which is black. This stuff in a small engine makes it smooth as silk. I used it all season in my leaf vacuum small engine. I could hear the difference. It was quieter and smoother.

Works just like the Mercedessource guy said it would.
Size: 5 Liter
After viewing a Mercedessource video (trusted Mercedes repair advice Youtuber and blogger) on which oil he liked for higher mileage Mercedes he pointed this out Semi-synthetic 10w-40 out. Called it “muddy” oil. Said it possibly helped with small oil seal leaks and seemed to slow oil loss in higer miles Mercedes. Also made the engines run more quietly. So I have been using in my wife’s high mileage Mercedes (185,000miles W211 2004 E500 4matic) which we baby and I work on. A true very high compression super car, everything he said at Mercedessource has turned out to be accurate. No more leaks. Quiet lifters. Cooler running. Wow. I had been using Mobil 1 full synthetic 0W-40 European Car Formula exclusively but tried this for the seal protection. Works great and no, it is not Mercedes spec but I will see when the harsh Utah winter hits. May switch to the Liqui-Moly 5W-40 Leichtlauf full synthetic (which does meet Mercedes 722.9 oil spec) for winter (I change the oil every 6 months regardless). Thanks for reading.
