FUNdamentals 32: How do I use the molecular repair hair oil?

You know what's FUN-damental? When your product works. We'll be breaking down key info + recommendations to help you get the most out of K18.

We love hair. We love expression. Frizz + damage? Not so much.


That’s why we engineered a peptide-powered molecular repair hair oil to strengthen, repair damage, and reduce frizz on all hair types—delivering your strongest, smoothest hair throughout your routine. 


Let’s break down how it works, and where it fits into any routine. 


how do I use it?

Just like all of our highly concentrated formulas, the molecular repair hair oil was made to use less, waste less, and still give you the best results. Start with 1-3 drops of this weightless formula on damp, towel-dried hair, applying from the mid-lengths to ends. Then you can build as needed without weighing hair down.


Did ya peep the molecular repair part of our oil’s name? Yup, our frizz-fighting oil boasts the same patented peptide as our molecular repair mask. In the oil, our peptide works at the innermost layers to reverse frizz-causing damage. Just wait 4 minutes after applying before you begin styling so it has time to soak in and do its thing. Once your hair is dry, you can go in with another 1-3 drops to smooth frizz and flyaways, and as a finisher to add 104% more shine*. 


so, where does it fit in my routine?

Cool thing is, our biotech breakthrough fights frizz on both damp and dry hair. Here’s what that looks like with the full K18 routine:

FUNdamentals 32: How do I use the molecular repair hair oil?

See where it says “style as usual”? This is the time to bust out our silicone-free oil. But what can you use it for? We’re glad you asked…


want to fight frizz and damage before drying or styling?

Use it on damp hair for clinically proven damage repair* and 24-HR frizz control*. 


seeing flyaways, split ends, or dullness after styling? 

Get 104% more shine* and a 78% reduction in split ends* on dry hair too! 


P.S. this oil really does it all. Use it before you reach for those hot tools to get 450°F (232°C) heat protection* and help prevent further frizz-causing damage long-term.


can I use it with my K18 mask?

Use the oil and mask together to get maximum hair strength with additional styling benefits. The hair experts know best, so we’ll let PRO stylist + educator Eric Vaughn show you how our leave-in molecular repair hair mask and oil work together in your routine. 

In short: you’ll use the mask first on clean, damp hair, then wait 4 minutes to let our peptide do its thing. When it’s time to “style as usual” after the mask, this is when you add 1-3 drops of the molecular repair hair oil. Wait 4 minutes for strengthening benefits from the K18PEPTIDE™, then you’re ready for frizz-free drying and styling. With this weightless formula, you can add another 1-3 drops as a finisher for science-backed smoothness, and shine. Oh yeah. 


See ya soon for more FUNdamentals.
