The gold standard of silk pillowcases, Slip has been creating pure silk products since 2004, ever since its founder Fiona Stewart was prescribed a silk pillowcase by her dermatologist. Unable to find one, she wrapped her pillow in the finest silk she could find, sparking the idea that became Slip – a brand that now has over 70 prestigious beauty awards under its belt. Not just a haircare hero, a Slip silk pillowcase reduces friction on the skin (hello, anti-ageing benefits) and is far less absorbent than cotton, meaning your nightly skincare products stay put on your skin. It’s not just pillowcases, either; you’ll find Slip silk scrunchies – including the bestselling Slip skinny hair ties – which prevent breakage, as well as Slip silk turbans or Slip silk hair wraps which reduce frizz, bedhead and maintain your hairstyle – all while you catch up on some beauty sleep.
