You’ve probably used an oil in your hair routine, so what makes our molecular repair hair oil so special? The science tells us that a lot of frizz is caused by deeper-level damage, so creating a product that only coats the outside of hair wasn’t going to cut it. We intentionally formulated with ingredients that work on two levels of the hair fiber for immediate + long-term strength and smoothness. 

 

Let’s meet the science star players that make this happen.

 

the inner layer player

Damaged hair is more susceptible to frizz, so the key to long-term frizz prevention is reversing the damage that causes it. Inside our molecular repair hair oil is our patented molecular repair technology: the K18PEPTIDE™. This peptide works at the molecular level to address frizz-causing damage—delivering clinically proven damage repair* in just 4 minutes.

FUNdamentals 33: What’s in our molecular repair hair oil?

the outer layer players 

Now we know when it comes to oil, you expect it to control frizz immediately—like those pesky flyaways around your face. So we couldn’t just leave you with long-term repair, we also wanted to employ ingredients that deliver immediate satisfaction. 

 

We engineered this product with natural oils that work on the surface AND past the cuticle layer for more effective frizz control. Nourishing ingredients like sunflower oil, hemisqualane, and squalane reinforce hair’s moisture barrier, delivering immediate frizz reduction and enhanced shine without weighing hair down. This weightless oil packs a punch, delivering 24-HR frizz control* and 104% more shine* with just 1-3 drops. 

 

the hot take ingredient 

To prevent further frizz-causing damage and break the frizz cycle, we formulated with avocado oil. We chose it for its high smoke point, meaning it resists breaking down at higher temperatures compared to other natural oils. So next time you reach for your hot tools, you can safely style with up to 450°F (232°C) heat protection*.

 

intentional frizz control 

We’re all about holistic hair health here, because why settle for temporary results, ya know? By harnessing an understanding of hair’s biology, we can strengthen both the external barriers that block damage and repair damage from the inside for a stronger, less frizzy structure overall. 

 

See ya soon for more FUNdamentals.
