Can I use the Molecular Repair Hair Oil instead of the mask?

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.

Does the Molecular Repair Hair Oil provide heat protection?

Yes, this oil provides heat protection up to 450°F/232°C.

Will the Molecular Repair Hair Oil leave buildup or weigh down my hair?

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.

Will the mask block the Molecular Repair Hair Oil from penetrating?

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.

Can I mix the oil and mask together?

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.

Dual-Action Frizz Control System: The perfect hair oil for frizzy hair, it targets frizz at two levels by reversing damage within the hair fiber and smoothing the cuticle surface for soft, manageable strands.
Biotech-Engineered Oil for Hair: Clinically proven to repair damaged hair*, our patented K18PEPTIDE formula works at the innermost layer of hair to strengthen and reverse damage that leads to frizz.
Lightweight + Shine-Enhancing: The weightless, silicone-free formula nourishes with avocado oil, sunflower oil, hemisqualane, and squalane to boost color vibrancy and increase hair shine by 104%* without buildup.
Heat Protection up to 450°F*: Designed to protect from heat styling tools, this hair oil heat protectant helps prevent further frizz-causing damage while reducing split ends by 78%*.
How to Use: Start with 1-3 drops and build as needed. Apply to damp, towel-dried hair from mid-lengths to ends for repair + frizz control. Apply to dry strands as a hair finishing oil to smooth and add shine. Use after the K18 Molecular Repair Hair Mask to complete your hair strengthening routine.
