            Can I use Sealing Formula every day?

            Yes, you can use the Sealing Formula Hair Oil daily to reduce frizz, boost shine, and add moisture. Use the amount that suits your hair’s density and porosity.

            How do you use Sealing Formula as an oil treatment?

            Start with clean hair. Split it into two sections and apply one full syringe of oil per side, coating from root to tip. Braid your hair to lock in the moisture.

            Can you use Sealing Formula on wet hair?

            Yes, you can use Sealing Formula on wet hair. It helps lock in moisture, reduce frizz, and makes detangling easier before styling.

            Will Sealing Formula help grow my hair?

            Sealing Formula Hair oil creates the perfect environment for healthy growth by sealing in moisture, strengthening, and protecting your strands from breakage - think of it as creating the ideal foundation for your hair to thrive naturally.
