What is the best silk for a pillowcase?

The best silk for pillowcases is 100% mulberry silk, ideally 22 momme or higher. Mulberry silk is smoother and stronger than other types, helping your skin and hair glide across the surface without friction.

Do silk pillowcases help if I sleep hot?

Yes. Silk is naturally breathable and temperature-regulating. Unlike cotton, which absorbs and holds heat, silk helps wick away moisture and feels cool against your skin. This makes it ideal if you “sleep hot” or have night sweats.

Are silk pillowcases good for skin?

Silk reduces creases and friction on the skin. It also absorbs less moisture than cotton, helping your skin stay hydrated overnight and allowing your skincare products to work better.

Do silk pillowcases help with hair?

Yes. A silk pillowcase helps prevent bedhead, frizz, and split ends by reducing tugging and breakage. Many people notice smoother, shinier hair after switching from cotton to silk.

What is momme weight and why does it matter?

Momme (mm) measures silk weight and density, similar to thread count in cotton.

  • 19 momme – entry level, softer but thinner

  • 22 momme – luxury balance of softness, strength, and durability

  • 25 momme – ultra-luxury, thicker and longer-lasting

Our pillowcases are 22 momme mulberry silk, the perfect sweet spot for everyday luxury.

How do I wash a silk pillowcase?

  • Use a gentle silk-safe detergent

  • Wash at 30°C on a delicate cycle or by hand

  • Air dry flat or hang out of direct sunlight

  • Avoid fabric softener and tumble drying

With proper care, silk pillowcases last for years without losing their smoothness.

Why are silk pillowcases more expensive than satin?

Many cheap “silk” pillowcases online are actually satin polyester. Satin may look shiny, but it doesn’t have the cooling, skin, or hair benefits of real silk. Genuine silk is a natural fibre, harder to produce, and far more durable — making it a better long-term investment.
