Get started here.
why skip conditioner before the mask?
Traditional conditioners leave a film on hair that blocks our peptide from penetrating effectively. Once the 4-minute wait time is up, feel free to use a conditioner, a leave-in, or any type of styling product.
Is the K18 PRO mask and take-home mask the same?
Yes, both formulas are the same. The PRO mask is conveniently sized for PRO use.
How often can I reapply HeatBounce?
Apply HeatBounce every time you apply heat, including if you switch between blow drying to hot tools.
Will the molecular repair hair oil leave buildup or weigh down hair?
No, it will not leave buildup or weigh down 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 or your clients are concerned about buildup, use our detox shampoo to remove 99% of product buildup after just 1 wash*.
*Disclaimers
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 that would block the oil from penetrating. Like layering different skincare products, the oil can be layered on top of the mask without impacting its performance.
Repair damage for hair like new* in 4 minutes.
