Silk pillowcases are not new, but over the past couple of years, they seem to have exploded in popularity, embraced by the beauty and wellness industries and credited with delivering smooth, shiny hair and wrinkle-free, supple skin. If we will buy one and try it? Let’s dig into the specific beauty benefits you can actually expect from silk pillowcases.

Silk pillowcases prevent frizzy hair

Thanks to silk's super smooth texture, hair glides over it without any friction which means you'll be less likely to wake up with frizzy hair, tangles, or bedhead, whereas cotton can snag hair and muss it up into a nest of tangles overnight. Sleeping on silk is a secret that women with textured and curly hair have been using for years to keep styles like braids and blowouts preserved for longer without adding frizz.

Silk pillowcases keep skin hydrated

Thanks to that super-smooth texture, this is actually true. Silk's smoothness “means it’s less apt to absorb moisture from the skin,” says Schultz, keeping skin nice and hydrated without zapping it of valuable moisture. That makes silk pillowcases great for anyone with dry skin (or for use in dry winter months).

Silk pillowcases keep hair healthy

In some ways, yes: They help keep hair hydrated, and Schultz says that silk can help with brittle hair. Cotton is more porous than silk, so traditional pillowcases absorb moisture from your hair, while silk leaves that hydration right where it belongs: in your hair. That means if you suffer from dry strands or a flaky scalp, a silk pillowcase will be a godsend.

Silk pillowcases regulate temperature

Silk may not be the most cooling bedding option, but it certainly does regulate temperature. According to Lexie Sachs, Associate Director of the Good Housekeeping Institute Textiles Lab, silk fibers are inherently temperature-regulating. Unlike cotton, which absorbs moisture, silk wicks moisture away to keep you dry and cool all night long.
