NuProtect™ Leave-In Primer

Most leave-ins stop at detangling. This one goes deeper. Powered by biodesigned elastin and keratin, it helps reinforce hair’s natural structure while NuProtect™ Complex shields from heat, humidity and environmental stressors.

Instead of heavy silicones that just coat the hair, this primer creates a lightweight, breathable shield that hydrates, detangles and protects against heat and environmental stress without weighing hair down or leaving residue, so strands feel smooth and natural.

Yes. In clinical testing, hair treated with the Leave-In Primer showed 73% less frizz after 24 hours in 80% relative humidity. That means the formula doesn’t just mask frizz — it actively defends against moisture in the air. How? The NuProtect™ Complex combines bioactive polyphenols and coconut alkanes to form a breathable barrier around each strand. This barrier helps limit water uptake, which is what normally causes hair fibers to swell and frizz. The result: smoother, more controlled styles that last, even when the weather doesn’t cooperate.

Yes! Since you heat style on non-wash days, you can absolutely use NuProtect™ Leave-In Primer on both damp and dry hair to keep it protected from heat and looking healthy.
