Is a Silk Pillowcase Worth It? The Complete Guide (2026)

When silk pillowcases first became popular, they were often associated with luxury hotels, celebrities and high-end beauty routines. Today, they've become much more accessible, leaving many people asking the same question:

Is a silk pillowcase actually worth the investment?

The short answer is that it depends on what you're looking for.

If you're expecting a silk pillowcase to completely transform your sleep overnight, you'll probably be disappointed. However, if you're looking for a more luxurious sleep experience, a fabric that's gentle on your hair and skin, and a simple way to elevate your bedtime routine, many people find that a genuine Mulberry silk pillowcase is well worth the investment.

In this guide, we'll explain what silk pillowcases are, how they compare with cotton and satin, what the evidence says, how to choose a quality pillowcase, and whether they're the right choice for you.

What is a silk pillowcase?

A silk pillowcase is exactly what it sounds like—a pillowcase made from natural silk fibres rather than cotton, polyester or satin.

Not all silk is the same, though.

The highest-quality pillowcases are typically made from 100% Mulberry silk, produced using fibres from silkworms fed exclusively on mulberry leaves. This creates silk that is exceptionally smooth, durable and consistent.

When shopping for a silk pillowcase, you'll often see references to Momme (pronounced "moe-me").

Momme measures the weight and density of silk. Rather than thinking of it as a thread count, it's better thought of as an indicator of the silk's substance and durability.

Generally speaking:

• 16–19 Momme is considered lightweight.

• 19–22 Momme offers a balance of softness and durability.

• 22 Momme is widely regarded as a premium choice for everyday use.

• Higher weights are often reserved for specialist luxury products.

A higher Momme doesn't necessarily mean "better" for everyone, but 22 Momme is often chosen because it combines a luxurious feel with excellent longevity.

Why are silk pillowcases so popular?

Silk pillowcases have become increasingly popular because they combine comfort, luxury and practicality.

Unlike many bedding upgrades that are purely decorative, a pillowcase is something you use every night. Many people enjoy the smooth feel of silk and appreciate the premium experience it brings to their bedtime routine.

Common reasons people choose silk include:

• A beautifully soft, smooth surface.

• A luxurious bedroom aesthetic.

• A naturally breathable fabric.

• Reduced friction on hair.

• A gentler feel against the skin.

• Long-lasting quality when properly cared for.

While individual experiences vary, these are among the reasons silk has remained popular for generations.

Silk vs cotton: What's the difference?

Cotton remains one of the most popular bedding materials in the world, and for good reason. It's durable, breathable and easy to care for.

Silk offers a different experience.

Neither fabric is objectively "better" for everyone.

Many people simply prefer silk because of the way it feels and the luxurious experience it creates.

Can a silk pillowcase help your hair?

One of the most commonly discussed benefits of silk pillowcases relates to hair.

Hair naturally moves as we sleep. Every time your head turns, your hair moves against your pillow.

Because silk has a smooth surface, it generally creates less friction than many cotton fabrics.

Many people report that this can help reduce:

• overnight tangles

• morning frizz

• bed hair

• hair snagging

This is one reason silk pillowcases are particularly popular among people with curly, textured, colour-treated or longer hair.

Results vary from person to person, and a silk pillowcase isn't a substitute for a good haircare routine, but many people enjoy the smoother sleeping surface it provides.

Can a silk pillowcase benefit your skin?

Silk is also popular with people looking to create a more luxurious skincare routine.

Compared with many cotton fabrics, silk generally creates less friction against the face throughout the night.

Many people also appreciate that silk absorbs less moisture than cotton, which is one reason it's often chosen by people who invest in evening skincare routines.

While a silk pillowcase shouldn't be viewed as a skincare treatment, it can be a comfortable and elegant addition to an overall bedtime ritual.

Is silk better than satin?

This is one of the most common questions people ask.

Although they can look similar, silk and satin are not the same thing.

Silk is a natural fibre.

Satin is a type of weave and is often made using synthetic materials such as polyester.

Both can feel smooth, but they differ in their composition, durability and overall feel.

People looking for a premium, natural material often choose genuine Mulberry silk.

Is 22 Momme worth it?

If you're investing in a silk pillowcase, quality matters.

Lower-quality silk may initially feel similar, but can be thinner and less durable over time.

Many luxury bedding brands choose 22 Momme because it offers:

• a substantial feel

• excellent durability

• long-lasting softness

• everyday practicality

Rather than replacing your pillowcase frequently, investing in higher-quality silk can provide better long-term value when properly cared for.

How do you care for a silk pillowcase?

Looking after silk is simpler than many people expect.

To keep your pillowcase looking its best:

• Wash on a delicate cycle at 30°C.

• Use a detergent designed for delicate fabrics where possible.

• Avoid bleach.

• Avoid tumble drying if possible.

• Air dry naturally.

• Iron on a cool setting if required.

Following the manufacturer's care instructions will help maximise the lifespan of your pillowcase.

Is a silk pillowcase worth the money?

For many people, yes.

Not because it promises dramatic overnight changes, but because it improves something you use every single day.

If you value:

• quality materials

• luxurious comfort

• thoughtful bedroom design

• premium bedding

• investing in long-lasting products

then a genuine Mulberry silk pillowcase can be a worthwhile purchase.

As with any premium product, quality matters. Choosing genuine Mulberry silk from a reputable retailer is likely to provide a better experience than lower-quality alternatives.
