What Thread Count Matters for Silk Pillowcases?
When it comes to luxury sleep essentials, silk pillowcases are in a league of their own. But not all silk is created equal—and if you're investing in one, thread count is a detail you don’t want to overlook. So, what thread count matters for silk pillowcases? And why should you care? Let’s break it down in a way that actually makes sense.
First, What Is Thread Count?
Thread count refers to the number of threads woven into one square inch of fabric—both lengthwise (warp) and widthwise (weft). In the cotton world, a higher thread count usually equals better quality. But with silk, the rules are different.
Silk uses something called momme weight (pronounced "mommy"). It’s a Japanese measurement that reflects the density and quality of silk. So while thread count still matters in overall construction, momme is actually a better indicator of silk quality.
Still, the two work hand in hand.
So, What’s the Best Thread Count for Silk Pillowcases?
For silk pillowcases, a thread count of 400 or higher is typically ideal when paired with a momme weight of 19 to 25. This combo gives you a durable yet ultra-soft pillowcase that holds up to nightly use, washing, and friction from your hair and skin.
Let’s put it simply:
-
Low thread count + low momme = flimsy, wears out quickly
-
High thread count + high momme = luxurious, long-lasting, effective
At Silkie, our silk pillowcases are designed with this perfect balance in mind—ensuring you get real, lasting benefits for your hair, skin, and sleep quality.
Why Does Thread Count Matter for Haircare?
Because silk pillowcases aren’t just a pretty bedtime accessory. They’re a functional tool in your haircare and skincare routine. A well-made, high-thread-count silk pillowcase helps:
-
Minimize friction that leads to frizz and breakage
-
Retain hair moisture overnight (unlike cotton which strips it away)
-
Prevent split ends and tangling, especially for curly or textured hair
-
Extend blowouts and salon-treated styles
If your pillowcase isn’t smooth and tightly woven, it won’t give you these benefits. It’s like using a plastic comb instead of a wide-tooth one—it just won’t work.
How Can You Tell If It’s High Quality?
Look for:
-
100% mulberry silk – the gold standard of silk types
-
Momme weight of 22 or higher
-
Thread count around 400+
-
Oeko-Tex certification – confirms it’s free from harmful chemicals
Cheap silk alternatives often advertise high thread count without considering momme. But without that density, you won’t get the silky texture or longevity that true luxury silk offers.
What About Satin?
Let’s clear this up: satin is a weave, not a fiber. Most satin pillowcases are made from polyester or synthetic blends. While they may feel soft, they don’t provide the same breathable, moisture-retaining benefits as real silk. And they’re nowhere near as gentle on hair.
That’s why Silkie only uses 100% mulberry silk for our pillowcases—because your hair and skin deserve the best.
Final Thoughts: Don’t Just Buy Silk—Buy Smart
Thread count absolutely matters, but not on its own. When you pair the right thread count with a high momme weight, you’re getting a pillowcase that actually does what it promises.
Want your curls to stay defined? Your skin to stay hydrated? Your hair to glide across your pillow instead of snapping in your sleep?
Then make sure your silk pillowcase checks all the right boxes.
