Pro Tip
If using the K18 molecular repair mask, apply the mask first on clean, damp hair, then wait 4 minutes.
Apply the molecular repair hair oil, and wait 4 minutes for maximum strengthening results.
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. The oil is for smoothing, styling and strengthening after the mask, and can be used on damp and dry 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, while natural oils work on the surface of hair without weighing it down.
Plus, you don’t need much of this highly concentrated formula to see results, just use 1-3 drops and build as needed. If you’re concerned about buildup, use our detox shampoo to remove 99% of product buildup after just 1 wash*.
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. Like layering different skincare products, the oil can be layered on top of the mask without impacting its performance.
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.
