We show you what you need to know about buying a silk pillowcase
Silk pillowcases are genuinely worth it for most people — but they're not perfect, and anyone telling you otherwise is selling something. The pros are well-evidenced and meaningful: less friction, better hydration, smoother hair, fewer sleep creases. The cons are real too: the cost, the care routine, and the fact that cheap "silk" is often anything but. Here's the full, honest picture so you can decide whether it's the right investment for you.
The Pros of Silk Pillowcases
Let's start with what silk genuinely does well — and there's plenty of it.
Less friction on hair and skin. This is the headline benefit and the most well-supported by evidence. Silk's naturally smooth surface reduces the dragging and tugging that cotton creates as you move during sleep. The Sleep Foundation notes that silk is gentler on hair than cotton or linen, helping to reduce breakage, frizz, and split ends. The same smoothness benefits skin — less friction means fewer sleep creases and less mechanical stress on delicate facial skin overnight.
Better moisture retention for skin and hair. Cotton is highly absorbent — it draws moisture away from your skin and hair as you sleep, leaving both drier by morning. Silk is far less absorbent, so your skin's natural hydration and your hair's natural oils stay where they belong. Board-certified dermatologist Dr. Anna Chacon explains that silk "is less likely to absorb moisture and natural oils from your skin and hair, helping to keep it hydrated and reducing the potential for irritation."
Your skincare products actually stay on your face. If you apply serums, retinoids, or night creams before bed, cotton absorbs a significant portion of them overnight. Silk doesn't — which means those expensive products work on your skin all night, not on your pillowcase.
Naturally hypoallergenic. Silk is naturally resistant to dust mites, mould, and common allergens — making it a genuinely better choice for anyone with sensitive skin, eczema, or allergies. It's not a treatment, but removing allergens from your pillowcase is a meaningful environmental change.
Temperature-regulating. Real Mulberry silk is breathable and naturally temperature-regulating — it stays cool to the touch in warm weather and adapts rather than trapping heat the way synthetic fabrics do. Particularly useful if you're prone to overheating at night or going through the menopause.
Durable and long-lasting. Quality 22 Momme Mulberry silk, properly cared for, will last for years without losing its smoothness. Unlike cheaper fabrics that pill, bobble, or lose their softness within months, well-made silk ages gracefully. Over the course of its lifespan, the cost-per-use is far lower than it appears upfront.

The Cons of Silk Pillowcases
Here's where we're straight with you — because understanding the real drawbacks helps you make the right decision.
The upfront cost. Real 22 Momme Mulberry silk costs more than cotton. That's simply a fact of what it takes to produce a natural protein fibre of this quality. It's worth noting that the cost compares well to a single facial, a mid-range serum, or a salon treatment — all of which it effectively replaces over time. But if budget is tight, the upfront price is a genuine consideration.
It requires more care than cotton. You can't just bung silk in a hot wash and tumble dry it. It needs a cool, gentle machine cycle (or hand wash) in a laundry bag, a non-biological fragrance-free detergent, and air drying flat away from direct sunlight. For most people this becomes second nature quickly — but if you want zero-maintenance bedding, silk isn't it.
It can feel slippery at first. If you're used to cotton, silk's smooth surface can feel surprisingly slippery the first few nights — both against your skin and in terms of the pillow moving around inside the case. This is something almost everyone adjusts to quickly, but it's worth knowing.
The market is full of fakes. This is perhaps the biggest practical con. Many products sold as "silk" are polyester satin — they look shiny but share none of the actual benefits of real silk. They trap heat, generate static, and wear out quickly. If you buy cheap, you almost certainly won't get real silk. Always look for 100% Mulberry silk, 22 Momme, Grade A, and OEKO-TEX certification.
Results vary by person. If your main hair concern is volume or your skin is naturally very oily, the benefits of silk may be less dramatic for you than for someone with dry, frizz-prone, or sensitive skin. Silk removes a set of specific environmental stressors — if those aren't your primary issue, the improvement will be smaller.
It's not a cure for anything. Silk won't reverse existing wrinkles, clear acne, or regrow hair. Anyone claiming otherwise is exaggerating. What it does is remove several nightly triggers and stressors — the results are real but cumulative, and they complement rather than replace a good skincare or haircare routine.
The honest verdict
For anyone with dry, frizz-prone, sensitive, or acne-prone skin — or anyone who applies skincare overnight and wants it to actually work — the pros of a quality silk pillowcase meaningfully outweigh the cons. You're in contact with it for 2,500 hours a year. The investment makes sense.
If you have naturally resilient skin and hair that isn't prone to dryness or sensitivity, the difference will be more subtle. But most people who make the switch notice something from the very first morning — and very few go back to cotton.
How to Get the Most From a Silk Pillowcase
If you decide to make the switch, here's how to make sure you're actually getting what you pay for and seeing the results:
Buy the real thing. 100% Mulberry silk, 22 Momme, Grade A, OEKO-TEX certified. These four criteria are non-negotiable if you want genuine benefits. Our Ivory 22 Momme Mulberry silk pillowcase meets all four — and comes with a 90-night money-back guarantee, so there's genuinely no risk.
Wash it every 2 to 3 days. Silk doesn't accumulate grime as quickly as cotton, but regular washing keeps it hygienic and performing at its best — especially if you're using it for skin or eczema concerns.
Use the right detergent. A gentle, fragrance-free, non-biological detergent — we recommend Ecover Wool and Silk. Avoid fabric softeners, bleach, and optical brighteners entirely.
Give it time. Hair benefits show up immediately. Skin benefits are more cumulative — most people notice a meaningful difference after three to four weeks. Don't write it off after two nights.

Frequently Asked Questions
Are silk pillowcases actually worth the money?
For most people, yes — particularly those with dry, sensitive, frizz-prone, or acne-prone skin. You're in contact with your pillowcase for around 2,500 hours a year. A quality 22 Momme silk pillowcase costs less than a single salon treatment or a mid-range moisturiser, and it lasts for years with proper care. The cost-per-use is genuinely low.
What's the difference between cheap and expensive silk pillowcases?
Mostly this: cheap "silk" pillowcases are usually polyester satin. They look similar but deliver none of the genuine benefits — they trap heat, generate static, and wear out quickly. Real 22 Momme Mulberry silk has longer filaments, a smoother surface, and genuine natural properties that polyester simply can't replicate. Always check for 100% Mulberry silk, 22 Momme, Grade A, and OEKO-TEX certification.
How long does a silk pillowcase last?
A quality 22 Momme silk pillowcase, properly cared for, should last two to five years — and many customers report theirs lasting considerably longer. The key is washing it correctly: cool water, gentle detergent, no tumble drying. It's not a pillow you replace every year the way cheap cotton often needs to be.
Will a silk pillowcase make my hair less greasy?
Counterintuitively, it can help. Cotton absorbs your hair's natural oils overnight, which can signal your scalp to overproduce oil to compensate — making greasiness worse. Silk doesn't strip that moisture, so your scalp's oil production is less likely to go into overdrive. It won't fix a genuinely oily scalp, but it removes one of the factors that can make it worse.
Is silk pillowcase worth it for someone without skin or hair concerns?
The beauty and skin benefits will be less dramatic. But many people still value it for the sheer comfort — real Mulberry silk feels noticeably different to sleep on, it regulates temperature well, and the hypoallergenic properties are relevant to almost everyone. Whether that's worth the premium is a personal call.
Can I machine wash a silk pillowcase?
Yes — our silk pillowcases are machine washable. Use a cool, delicate cycle in a laundry bag with a gentle non-biological detergent. No tumble drying — air dry flat away from direct sunlight. It's a bit more involved than cotton, but once it's part of your routine it takes no more than a couple of extra minutes.
Still on the fence? Try it for 90 nights with our money-back trial — genuinely no risk. Our Grade A, 22 Momme Mulberry silk pillowcases are OEKO-TEX certified and backed by over 1,500 five-star reviews.
