Silk Pillowcases for Hair: What the Evidence Can and Can’t Say

Silk's smooth surface can reduce friction compared with rougher fabrics, which is why many people choose silk pillowcases for hair. That does not make every beauty claim proven.

Good Housekeeping currently evaluates silk pillowcases for physical performance and tester experience, which is more useful than relying only on merchant testimonials.

Check fiber content, momme, closure, care and size first.
