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.

Light, nongreasy oil, using only 1 drop!

This is the first hair oil I have used, so I have nothing to compare it to. However, this oil eliminates flyaway hairs on my shoulder length hair with only 1 drop. It does not leave a greasy feel and adds a bit of shine as well.

Repair Hair Oil

This product has truly improved the strength and the softness of my hair. I had a lot of shedding before using this product and I did not like using a lot of products out there because the product would leave my hair oily and would not hold curls. K18 molecular repair oil was very effective for my hair.

It works!

I've used it once...3 drops on towel dried medium length hair made a noticeable difference in shine and silkiness.
