A silk headscarf slides off because of its weave, not its fibre. Crêpe de chine at 16 to 19 momme grips almost as well as cotton, while charmeuse and satin need pins to hold a fold until evening.
You have already been told silk is the right fibre for hair, and that advice is not wrong. It stops one level above the purchase: which silk, at what weight, in which weave.
Momme is the unit silk is sold by, roughly 4.34 grams per square metre (GSM), and a listing that omits it tells you nothing about how the scarf will sit.
Smoothness and grip pull in opposite directions. The buyer who bought a light habotai square got the right fibre in the wrong weave.
Silk, modal, cotton and polyester cover almost every headscarf worth buying, and they separate first on a number you can look up. Standard moisture regain, measured at 20 °C and 65 percent relative humidity, runs from 9 to 11 percent for silk down to 0.4 percent for polyester.
| Fibre | Moisture regain | Where it wins |
|---|---|---|
| Silk | 9-11% | Overnight hair contact |
| Modal | 10-13% | Humid days, sensitive scalp |
| Cotton | 7-8% | A scarf that must not need adjusting |
| Polyester | 0.4% | A scarf washed twice a week |
Polyester's 0.4 percent is the whole gap. The fibre absorbs almost no sweat vapour, so a wrap worn through a hot afternoon can read clammy long before it looks damp.
Modal earns the sensitive-scalp case on measurement rather than marketing. A 2023 study in the Journal of Textile Engineering and Fashion Technology puts knitted modal at 0.389 mm thick against cotton's 0.447 mm, and regenerated fibres absorb more moisture than cotton does.
Overnight contact changes the answer, which is why pillowcases and bonnets sort differently from a scarf worn for an afternoon. For a headscarf, the weave you buy decides what happens next.

A silk headscarf belongs in the 12 to 14 momme band, about 52 to 60 GSM: fine enough to knot, opaque enough over a light scalp. Only one weave is worth going heavier for.
- **Habotai, 8 to 12 momme (35 to 52 GSM):** the lightest square sold as silk, and the one that slides off within the hour. Buy it for linings.
- **Silk twill, 10 to 14 momme (43 to 60 GSM):** holds a knot far better than satin, but still wants a band or two pins all day.
- **Charmeuse, 12 to 14 momme (52 to 60 GSM):** the overnight square. Charmeuse runs 12 to 30 momme as a fabric; 12 to 14 is the scarf end.
- **Crêpe de chine, 16 to 19 momme (70 to 82 GSM):** the wrap weight. Not slippery, and close to cotton for staying put.
The difference between these weaves is the float, not the fibre. A satin structure carries long lengths of yarn across the surface for shine, and those floats slide over hair and scalp alike.
Plain and crêpe structures lock the yarns down. Long floats also abrade fastest, so the smoothest square in the drawer goes thin first.
Check the momme before you order. A custom silk scarf quoted without a weight is a scarf whose behaviour nobody has committed to.

A polyester scarf is good for hair in the way most buyers mean it. A polyester satin gives you nearly all the low-friction surface a silk satin does, because the smoothness comes from the weave and not the fibre.
Where polyester falls behind is moisture. Its standard regain is 0.4 percent against silk's 9 to 11, so it holds almost no sweat vapour on a hot head or under an overnight wrap.
The verdict splits inside the fibre rather than between fibres. Satin polyester is the hardest headscarf to keep on, and bobby pins or a grip band are the fixes that work. Non-shiny polyester wears about like cotton.
For abrasion resistance, polyester ranks second only to nylon and ahead of cotton, which makes it the sensible pick for a scarf washed twice a week. On that pattern a non-shiny polyester scarf is a better buy than silk, and it is not a compromise.

A head wrap needs a fabric that grips and a shape a square scarf does not have. Wraps sell as long rectangles, roughly 19.5 to 40 inches wide by 65 to 72 inches long. Square scarves come at 53, 65, 90 and 110 cm.
A 90 cm square is not a short wrap. The missing length is what a turban twist uses to hold itself, and at 72 inches even long hair can tuck in fully.
Fabric follows from the shape. Cotton, non-shiny polyester and crêpe de chine all hold a wrap; silk and polyester satins do not. The usual remedy for a slipping wrap is a grip band rather than a different scarf.
Which head wrap styles you can tie is set as much by the length you bought as by the fibre.

Wash and ironing limits come from the care label, not from the fibre. GINETEX puts it plainly in the ISO 3758:2023 symbol system: the maximum temperature is chosen from the label and never from the fibre content.
| Symbol | Maximum temperature |
|---|---|
| One iron dot | 120 °C, no steam |
| Two iron dots | 160 °C |
| Three iron dots | 210 °C |
| Hand wash | 20 to 30 °C |
| Machine washtub | 30 to 95 °C by symbol |
Momme is not a grade. It is mass per square metre, and mass is what abrasion resistance is built from. A 19 momme crêpe de chine therefore outlives a 12 momme habotai in the same drawer.
Every wash moves that number the other way. Laundering lowers abrasion resistance and the damage accumulates cycle by cycle, which is the case for hand washing at 20 to 30 °C.

Start from what the scarf has to survive, not from the fibre name. For hair contact overnight, a 12 to 14 momme silk charmeuse square is the specification worth paying for.
For a wrap that has to hold its fold through a working day, a 16 to 19 momme crêpe de chine or a mid-weight cotton beats that square outright. Grip comes from the weave and the weight, not from the fibre on the label.
One case makes the cheap answer simply right. A scarf that lives on a hot head and goes through the wash twice a week does better in non-shiny polyester than in either of those silks.
Name the job first and the material question answers itself.
