Keep reading below to find out if silk pillowcases could help your hair and skin. What makes it a silk pillowcase?   Most pillowcases are made from cotton or microfiber, and come included in a set of sheets. You can also buy silk or satin pillowcases, both of which have a smoother texture than cotton and microfiber and are meant to help give you better hair or skin. Silk pillowcases are made from, well, silk, a natural protein fiber from silk worms that's soft and breathable, meaning it allows air to pass through. Silk is more expensive than cotton and other kinds of fibers, which is why silk pillowcases are likewise more expensive than others. Satin pillowcases are cheaper than silk because satin can be made from a variety of different fibers woven in a certain way to give the "shiny" satin feel and effect, according to manufacturer Lily Silk. Satin is typically made from polyester and has a similar smooth texture to silk, but is generally less breathable.

That's because as you move around in your sleep, your hair rubs against your pillowcase, causing friction that can lead to tangles and even breakage. Silk pillowcases can help preserve your style and keep your hair smoother than traditional cotton pillowshells, according to hairstylists, because they put less friction on your hair.  "Silk pillowcases reduce friction and are not as absorbent of moisture, therefore they can reduce frizziness and help you maintain moisture [in your hair] throughout the night," says Joseph Maine, celebrity hair stylist and co-founder of Trademark Beauty.  All different hair types that can benefit from silk pillowcases, but people with fine, curly or blonde hair may find it especially helpful, according to Shelly Aguirre, stylist at Maxine Salon in Chicago. "Blonde hair tends to be more fragile, so the silk will help prevent more damage. Also, curly hair tends to get frizzy with the friction of cotton, so the silk will help the hair 'glide' instead," Aguirre says. If you have oily hair, a silk pillowcase may not be the best choice, since a cotton pillowcase will absorb oil better, according to Aguirre. Silk pillowcases will be more beneficial if you have dry hair, or are experiencing breakage. 10 REASONS TO OWN A SILK PILLOWCASE Keep your face healthy. Your face has more contact with your duvet covers than any other fabric.
