satin hair pillowcase

Listings show two main materials: 100% silk (including pure mulberry silk in some listings) and 100% polyester satin. Some products are labeled as silk while others are labeled as polyester satin.

Common sizes shown are Standard (~20" x 26"), Queen (~20" x 30"), and King (~20" x 36"), so dimensions typically range from about 20" x 26" up to 20" x 36".

Descriptions commonly claim reduced friction to minimize tangles and frizz, lower moisture absorption to help skin retain hydration, and a smoother surface that can reduce sleep lines and help protect eyelashes and delicate facial skin.

Care instructions vary by material. Polyester satin listings generally specify machine wash and tumble dry. Silk listings often note machine wash but recommend line drying or laying flat to dry. Check the specific product care label for the manufacturer’s instructions.

Some listings provide numeric thread counts (examples shown include 400 and 600), while several polyester satin items mark thread count as not applicable. Commonly described finishes and features include a "silky-smooth satin finish," wrinkle-resistant, hypoallergenic, and other fabric treatments noted by the seller.

At least one listing explicitly shows OEKO-TEX STANDARD 100 certification and provides the certification number 21.HCN.46585.

Many listings describe breathability or cooling properties. Silk listings in particular often state they are "highly breathable" and "temperature-regulating," and descriptions and reviews frequently note a cool or non-absorbent sleeping surface for improved comfort.
