Smoother and shinier hair becomes more attractive. Here's what you need to know

Imagine going to bed with dull, damaged hair and waking up with silky, shiny tresses. It may sound like a particularly good dream rather than reality, but there’s a product you might want to add to your routine that could bring that fantasy into the real world. Ladies and gents, I’d like to introduce you to overnight hair masks. The nourishing formulas repair your hair while you sleep. I know the the idea of an overnight hair mask might sound like a sticky mess (who wants a rich hair mask smeared all over their silk pillowcase?), but these particular elixirs are formulated to leave zero residue. Many don’t even need to be washed out—you can just wake up and go.

“Overnight hair masks let your hair soak in deep hydration and nourishment while you sleep, making your mane softer, shinier, and more manageable by morning,” says Leo Izquierdo, co-founder of IGK Hair Care. “The convenience of leaving it on overnight means you don’t have to wait around in the shower—just apply and forget it! It’s especially great for repairing damage, restoring moisture, and perfect for those who work out in the morning, as it helps protect your hair from sweat and keeps it looking fresh all day.”
