## 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.
