The Lunelle Difference
Why a silk pillowcase?
A silk pillowcase changes how your hair and skin experience sleep. Cotton is absorbent and creates surface friction, it draws moisture from your face and grips your hair as you move. Silk does neither. The smooth surface lets hair glide across the pillow without resistance, reducing breakage, frizz and tangles overnight.
For skin, the low-friction surface means fewer sleep creases and less moisture loss. Dermatologists regularly recommend silk pillowcases for sensitive skin, and for anyone using skincare products before bed, silk keeps those products on your face rather than absorbed into the pillow.
At Lunelle, every pillowcase is 100% Grade 6A mulberry silk, the highest purity grade available. Not blended, not a silk-feel fabric. Pure silk, in two momme weights, so you can choose the weight that suits your sleep style.
Less friction overnight
Hair glides across silk rather than catching against cotton fibres. Fewer tangles, less frizz, less breakage.
Hydration stays on your skin
Silk does not absorb moisture the way cotton does. Your skincare and natural oils stay where they belong.
100% Grade 6A mulberry silk
The highest purity grade available. Every Lunelle pillowcase is pure silk, not blended or silk-feel fabric.
Gentle on all hair types
Particularly beneficial for curly, colour-treated and fine hair, where overnight friction causes the most damage.
Hair and skin
Silk pillowcases for hair
The friction between cotton and hair overnight is one of the main causes of frizz, breakage and split ends. Every time you move in your sleep, cotton fibres create resistance against the hair shaft. Over weeks and months, this builds up as visible damage.
A silk pillowcase eliminates that resistance. Hair moves with the fabric instead of against it. The difference is most noticeable for people with curly, textured, fine or colour-treated hair, where overnight friction causes the most visible damage. But the benefit applies to all hair types.
Both our 22 momme and 30 momme pillowcases deliver this benefit. If you are unsure which weight to choose, our 22 momme collection is the most popular starting point.

22 momme or 30 momme: which is right for you?
Momme is the weight measurement for silk fabric. Think of it like thread count for cotton, a higher number means more silk per square metre. Both weights are 100% Grade 6A mulberry silk. The difference is in feel, breathability and durability.

Frequently asked questions about mulberry silk pillowcases
What is a mulberry silk pillowcase?
A mulberry silk pillowcase is made from 100% silk produced by Bombyx mori silkworms fed exclusively on mulberry leaves. This produces a finer, smoother and more uniform fibre than wild silk or synthetic satin. The result is a fabric with a natural low-friction surface that lets hair glide rather than catch overnight, and does not absorb moisture the way cotton does. At Lunelle, every mulberry silk pillowcase uses Grade 6A silk, the highest purity grade available, certified to the OEKO-TEX STANDARD 100.
Are mulberry silk pillowcases worth it?
Yes, for most people who sleep on them nightly. The core benefit is reduced friction: silk's smooth surface lets hair glide rather than snag, which means less breakage, frizz and tangles by morning. Silk also does not absorb moisture the way cotton does, so your skin stays better hydrated and skincare products stay on your face rather than transferring to the fabric. A well-cared-for mulberry silk pillowcase typically lasts one to two years of nightly use, making the per-night cost modest compared to the benefits.
What is Grade 6A mulberry silk?
Silk is graded A to C, with A being the highest quality. Within Grade A there is a further sub-grade from 1A to 6A, where 6A is the finest. It indicates the longest, most uniform and least blemished silk filaments available, producing a smoother, more lustrous fabric with fewer imperfections. Grade 6A mulberry silk is the highest purity grade commercially available. All Lunelle pillowcases use Grade 6A mulberry silk and are certified to the OEKO-TEX STANDARD 100, confirming the fabric is free from harmful substances.
What is the difference between 22 momme and 30 momme silk?
Momme is the weight of the silk fabric per square metre. A 22 momme silk pillowcase is lighter, more breathable and softer in drape, ideal for everyday use and warmer sleepers. A 30 momme silk pillowcase uses more silk per square metre, giving it a heavier, denser feel and greater durability over time. Both weights are 100% Grade 6A mulberry silk and deliver the same low-friction benefits for hair and skin. The choice comes down to personal preference: 22 momme is the most popular everyday choice, 30 momme is the premium step up.
Are mulberry silk pillowcases good for hair?
Yes. Cotton creates friction against hair overnight, which causes breakage, split ends, frizz and tangles. A mulberry silk pillowcase eliminates that friction. Hair moves with the fabric rather than catching against it, so you wake up with noticeably fewer tangles and less frizz. The benefit is most visible for curly, textured, fine and colour-treated hair, where overnight friction accumulates as visible damage over weeks and months. Switching to a mulberry silk pillowcase reduces that damage at the source.
Do silk pillowcases help with hair growth?
Silk pillowcases do not directly stimulate hair growth, but they reduce the friction and breakage that makes hair appear thinner or slower to grow. By minimising overnight damage to the hair shaft, silk helps you retain more of the length you are already growing. For people with fragile, chemically treated or heat-styled hair, reducing overnight breakage makes a visible difference to length retention over time.
Are mulberry silk pillowcases good for skin?
Yes. A mulberry silk pillowcase benefits skin in two practical ways. First, the smooth surface creates far less friction than cotton, reducing the compression and dragging that contributes to sleep lines over time. Second, silk does not absorb moisture or skincare products the way cotton does, so hydration and serums you apply before bed stay on your face rather than transferring to the fabric. Dermatologists often recommend silk pillowcases for sensitive, acne-prone and reactive skin, as the lower friction and reduced moisture loss reduce overnight irritation.
How do I know if a silk pillowcase is genuine mulberry silk?
Look for four things. The label should say 100% mulberry silk, not just silk, satin, silky or silk-feel. The fabric should have a charmeuse weave with a shiny face and a slightly matte back. A price far below the real-silk market rate is a strong warning sign that the product is synthetic satin. An OEKO-TEX STANDARD 100 certification provides independent confirmation that the textile has been tested and verified. All Lunelle pillowcases carry this certification and are made from 100% Grade 6A mulberry silk.
How do I wash a mulberry silk pillowcase?
Wash on a cold, gentle or delicate cycle (30 degrees or below) inside a mesh laundry bag, using a mild silk-safe detergent or a small amount of gentle shampoo. Do not tumble dry on high heat. Lay flat or hang to dry away from direct sunlight. Iron on the lowest silk setting if needed, or smooth by hand while the fabric is slightly damp. Avoid fabric softener and bleach entirely. All Lunelle mulberry silk pillowcases are machine washable and hold their sheen well with proper care.
How long does a mulberry silk pillowcase last?
With proper care, a 22 momme mulberry silk pillowcase typically lasts one to two years of nightly use, roughly 100 to 150 gentle machine washes. A 30 momme pillowcase, being denser, generally outlasts the 22 momme under the same conditions. The main factors that shorten the lifespan are hot washing, harsh detergents, tumble drying on high heat and exposure to direct sunlight when drying. Rotating between a set of 2 pillowcases extends the life of each one, as each is washed less frequently.
What sizes are the mulberry silk pillowcases available in?
Lunelle mulberry silk pillowcases are made to the standard UK pillowcase size, fitting a standard UK pillow (48cm x 74cm). The same size fits a US standard pillow. All pillowcases come with a hidden zip closure to keep the pillow in place throughout the night. 22 momme pillowcases are available as a set of 2. 30 momme pillowcases are available both individually and as a set of 2.
Do you ship mulberry silk pillowcases to the United States?
Yes. Lunelle ships internationally including to the United States, Canada and other English-speaking markets. Free standard delivery applies to UK orders over £49. International shipping rates are calculated at checkout. Both 22 momme and 30 momme mulberry silk pillowcase sets are available for international orders in all five colours. All orders come with a 60-day returns policy.
