Our Controlled Chaos Silk Pillowcase fabric will make sure that you won't wake up with the "bed head" look that you get from sleeping on cotton pillowcases. It's perfect for helping protect your hair from damage or breakage while you sleep. During the night, your scalp produces natural oils that are meant to moisturize your hair, but your cotton pillowcase may be soaking it up instead. This might leave your hair feeling tangled or even dry come morning — especially if you move around a lot in your sleep. Silk pillowcases can help your hair retain its moisture throughout the night. Unlike cotton, which can cause possible breakage, silk also helps to preserve your style because it is slippery.
