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. ## Frequently Bought Together - K18 Molecular Repair Hair Oil, Weightless Oil for Stronger, Healthier Hair, Suitable For All Hair Types - K18 Damage Shield Protective Conditioner, Protects Hair from Daily Damage, Improves Strength & Shine, 8.5 Fl Oz - K18 Damage Shield Protective Shampoo, Reduces Frizziness & Tangles, Maintains Hair Health, 8.5 Fl Oz --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/550040335-k18-molecular-repair-hair-oil-weightless-oil-for-stronger-healthier](https://www.desertcart.us/products/550040335-k18-molecular-repair-hair-oil-weightless-oil-for-stronger-healthier) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-24*
