Enter: the LOC method. A popular term in the curl community that isn’t so difficult to add to your post-shower routine (you may even have all the products you need at the ready). If you find your strands practically screaming for moisture, consider this clever three-step technique to lock in the hydration. It’s been a popular topic among many natural hair forums, where beauty fans discuss their own natural hair journeys—including what helps keep their curls healthy and hydrated. One of those tried-and-true ways is to condition and seal the hair shaft immediately post-wash. And that’s where this layering order comes into play. That’s not to say waves and loose curls (types 2a to 2c) can’t benefit from the LOC method, too. The LOC method simply refers to a layering technique—so you can sub in any products you please. You’ll want to select the right products for your individual hair texture, “especially when it comes to selecting your oil,” says Nick Stenson, celebrity hairstylist and artistic director of Matrix.

Generally, the LOC method is best for high porosity hair—meaning, water tends to flow more freely in and out of your strands. Your hair absorbs water and product easily, but it also can evaporate at a quicker rate—that’s why sealing in that water with an occlusive (hello, LOC method!) is sublime. Folks with low porosity hair, don’t fret: You can use the LOC method, too. You just need a slightly different approach, as your strands have denser cuticles and a harder time absorbing water and product. Specifically, the “liquid” part of the LOC equation becomes even more important: You’ll want to make sure your hair stays wet as you apply your oil and cream—you may even want to use steam (like from the shower) while applying to help open the cuticle and make it easier for the water and moisture to seep in. It makes sense: In order to lock in moisture, you have to, well, add some in the first place. “Water is moisture,” Dickey says. So in order for the LOC method to have any lasting benefits, knowing how often to rinse is a key point.
