Review: K18 is top of its game - I’ve tried quite a few hair oils and this one is easily one of the best I’ve used. It’s really lightweight so it doesn’t leave my hair greasy, but it still makes it look smoother and shinier. I only need a couple of drops and it sorts out flyaways straight away, especially on the ends. It also works well on both damp and dry hair which I like. After a few uses my hair feels softer and a lot more manageable. It’s definitely on the pricey side, but a little goes a long way so the bottle lasts ages.
Review: Tames wild hair - This has transformed my hair routine. Keeps my hair controlled and can now go a lot longer between washes.

## Questions & Answers

**Q: Can I use the Molecular Repair Hair Oil instead of the mask?**
A: We recommend using the oil with the mask for maximum molecular repair with additional styling benefits. Think of the mask as a damage repair treatment after washing your hair.

**Q: Does the Molecular Repair Hair Oil provide heat protection?**
A: Yes, this oil provides heat protection up to 450°F/232°C.

**Q: Will the Molecular Repair Hair Oil leave buildup or weigh down my hair?**
A: No, it will not leave buildup or weigh down your hair. This weightless oil is powered by intentional ingredients to reduce frizz-causing damage on the molecular level inside the hair fiber.

**Q: Will the mask block the Molecular Repair Hair Oil from penetrating?**
A: No, the mask will not block the Molecular Repair Hair Oil from penetrating. The mask is a highly concentrated treatment without any fillers so it won’t block the oil from penetrating.

**Q: Can I mix the oil and mask together?**
A: Instead of mixing the oil and mask together, get the most effective repair and styling benefits by using the mask first, waiting 4 minutes, and then applying the oil.
