Silk Pillowcases for Curly Hair — Protect Your Curls Overnight
Curly hair deserves a surface that works with your texture, not against it. Standard cotton pillowcases create friction that can rough up the cuticle layer, leaving you with frizz, tangles, and flattened curls by morning. Poshey silk pillowcases are crafted from premium 22 momme mulberry silk — a smooth surface that helps hair glide more smoothly so your curls, coils, and waves stay defined while you sleep. Whether you wear your hair in a pineapple, a loose twist-out, or fully free, a silk pillowcase helps protect styled hair overnight and may help reduce frizz caused by friction. Every Poshey pillowcase is OEKO-TEX certified silk, machine washable, and finished with a hidden zipper to keep everything in place. Choose from queen, king, and standard sizes in a range of colors that complement any bedroom. Below, you'll find the right pillowcase for your curl pattern, pillow size, and budget.

Why Curly Hair Benefits from a Silk Pillowcase
Curly, coily, and wavy hair textures share one thing in common: they're more prone to tangling and frizz when they meet a rough surface. Cotton fibers — even high-thread-count ones — create drag on the hair cuticle as you move during sleep. That friction can disrupt curl clumps, pull moisture from strands, and leave you with a tangled mess to detangle in the morning.
Silk is gentler than rough cotton. Its smooth surface helps reduce friction, allowing curls to glide rather than snag. For anyone who spends time defining their curls with products, twist-outs, or roller sets, a silk pillowcase helps protect styled hair overnight so your morning routine is shorter and your curls look fresher on day two (and even day three).
Poshey pillowcases are made from 22 momme mulberry silk, which is dense enough to feel substantial against the pillow yet breathable and cool to the touch. If you also want to protect your skin while you sleep, silk offers a smooth surface for skin with less tugging on delicate facial skin — a dual benefit that makes upgrading your pillowcase an easy decision.

How to Choose the Right Size and Weight
Choosing the right silk pillowcase comes down to two decisions: pillow size and silk weight.
Pillow Size
- Standard (20" × 26") — Fits most standard and standard/queen pillows. A great starting point.
- Queen (20" × 30") — The most popular size. Offers extra surface area, which is ideal if you move around at night or have longer hair.
- King (20" × 36") — Best for king-size pillows and anyone with very long or voluminous curls who wants maximum coverage.
All Poshey pillowcases feature a hidden zipper enclosure so the pillow stays put — no bunching or slipping off during the night.
Silk Weight (Momme)
Momme is to silk what thread count is to cotton. Higher momme means a denser, more durable fabric. Poshey uses 22 momme silk across the collection — the sweet spot for a smooth feel that's substantial enough to last through years of regular washing. Anything below 19 momme tends to feel thin and wears out quickly.

Silk vs. Satin: Which Is Better for Curly Hair?
This is one of the most common questions curly-haired shoppers ask, and it matters because the two are not the same thing.
Silk is a natural fiber produced by silkworms. Mulberry silk — the variety Poshey uses — is the highest grade, known for its uniform fibers, natural sheen, and breathable feel. It's cool to the touch and naturally temperature-regulating.
Satin is a weave pattern, not a fiber. Satin pillowcases are often made from polyester, which mimics the smooth surface of silk but is a synthetic material. Polyester satin can trap heat and doesn't breathe the way natural silk does.
Both reduce friction compared to cotton, but mulberry silk offers a gentler, more breathable experience — especially important for anyone who sleeps warm or lives in a humid climate where curls are already battling moisture levels. Poshey's OEKO-TEX certified silk means the fabric has been independently tested, giving you confidence in what touches your hair and skin every night.

Caring for Your Silk Pillowcase
One of the biggest myths about silk is that it's high-maintenance. Poshey pillowcases are machine washable — just follow a few simple steps:
- Use a mesh laundry bag. This protects the silk from snagging on zippers or buttons from other items.
- Select a gentle or delicate cycle with cold water.
- Use a mild, liquid detergent. Avoid bleach and fabric softener — silk doesn't need either.
- Air dry flat or tumble dry on the lowest heat setting. Silk dries quickly, so high heat isn't necessary.
With proper care, a 22 momme silk pillowcase maintains its smooth feel and luster for years. Most Poshey customers rotate two pillowcases so one is always fresh while the other is in the wash.
If you're building a complete silk sleep routine, consider adding a silk sleep mask — the same care instructions apply, making laundry day simple.

Frequently Asked Questions
What size silk pillowcase should I get for curly hair?
Queen size (20" × 30") is the most popular choice because it gives curly hair extra room to spread out without bunching. If you have very long or voluminous curls, a king size offers even more surface area. All Poshey pillowcases have a hidden zipper to keep the pillow secure.
Will a silk pillowcase help with frizz on curly hair?
Silk's smooth surface helps reduce friction between your hair and the pillow, which may help reduce frizz caused by friction. Many curly-haired sleepers notice their curls stay more defined overnight compared to sleeping on cotton.
What is 22 momme silk and why does it matter?
Momme is a unit of weight for silk fabric. 22 momme is a dense, premium weight that feels substantial and holds up well over time. Lower-momme silk (16-19) is thinner and may wear out faster. Poshey uses 22 momme mulberry silk across its pillowcase collection.
Can I machine wash a Poshey silk pillowcase?
Yes. Poshey silk pillowcases are machine washable. Use a mesh laundry bag, cold water, a gentle cycle, and a mild liquid detergent. Air dry flat or tumble dry on the lowest heat setting. Avoid bleach and fabric softener.
Is silk or satin better for curly hair?
Both reduce friction compared to cotton, but silk is a natural fiber that's breathable and cool to the touch, while most satin pillowcases are made from synthetic polyester. Mulberry silk offers a gentler, more breathable sleeping surface for curly hair.
