I and every other beauty editor in the States are obsessed with Slip's silk pillowcases. Whereas cotton can tug at your hair and your skin while you sleep, the high-grade, long-fibre mulberry silk used in Slip's pillowcases helps reduce friction, leaving your hair silkier and less frizzy and, if you're a side sleeper, your skin less creased when you wake up.
But what I now can't go to sleep without are Slip's Silk Scrunchies (£39 for a three-pack), which are made of the same pure silk as the pillowcases. Hairstylists consistently gave me grief for the breakage along the middle of my hair, which they attributed to sleeping with my hair tied up in a regular old elastic band. And while I probably still shouldn't sleep with my hair up, at least I know the silk scrunchies aren't wreaking as much havoc on my hair; not to mention they leave my hair less creased in the morning (meaning I can also hit snooze a couple extra times before work).
