FAQ
I have very thin, fine hair. Will Lock & Seal work for me?
Or Will Lock & Seal weigh my hair down? Lock & Seal is a powerful treatment oil that increases moisture retention so it might weigh down finer or thin hair.
What is Anti-Breakage Technology?
The Anti-Breakage Technology in Lock & Seal is engineered to rebond damaged hair cuticles and split ends for up to 5 washes, so your hair stays smooth and shiny between wash days.
At what step in my Wash Day Ritual do I use Lock & Seal?
We recommend using Lock & Seal on clean hair, after Dew Magic Leave-in and your styler.
