plays well with others

The molecular repair hair oil works on its own and can be paired with the molecular repair service.
what's the difference?
Think of the molecular repair service as damage repair treatments used before and after services. The oil is for smoothing, styling, and strengthening after the mask, and can be used on damp and dry hair.
why wouldn't I just use the oil?
We recommend using the oil with the molecular repair service to get maximum molecular repair results with additional styling benefits.
when would I use both?
Use the molecular repair service pre and post-salon service to reverse hair damage in 4 minutes. You can layer the oil on top of the mask after the 4-minute processing time for additional frizz-reducing, styling, and heat-protecting properties.

got questions?

Get started here.

Does the molecular repair hair oil work on all hair types?

Yes, the molecular repair hair oil works on all hair types.

Does the molecular repair hair oil provide heat protection?

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

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.

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*.

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.

WOW

First I’m not a review writer. But I had to review this. I have long thick curly hair. I am 60 so my hair has some grey with more corse texture. This stuff is amazing! I’m in disbelief of how it soothed my frizz. I also live in Florida in the humidity.

I also use the K18 masque and repair products. My hairdresser used on my hair.

best hair oil!

this oil is longlasting ( since you only have to use a drop or two at a time) and it leaves my hair feeling better than any other oil I've used before!

Game changer!

I was initially impressed by the leave-in hair mask (and still am), but this product is the holy grail. I’ve used it in wet hair to allow it to air dry my wavy/curly hair. It significantly reduced frizz. Today I used it on damp hair and blow dried it. No need to straighten my hair. It left me with shine, body, and smooth locks. It doesn’t leave it greasy either. I’ve never had a product do that for me. Since growing out my gray, I’ve struggled with the new texture and this product has made it manageable again.
