Mulberry Silk in Winter: Dry Skin, Hair, and Cold — What it Really Changes
What winter does to your skin and hair at night
Winter creates two simultaneous aggressions. The outdoor cold dries out the skin barrier, and indoor heating lowers air humidity levels (often 20 to 30%, compared to an ideal 50 to 60%). Result: skin loses water faster at night than the rest of the year, and hair becomes static at the slightest friction.
On a cotton pillowcase, every head movement creates friction on an absorbent and slightly rough fiber. When the skin is already weakened by the cold, this effect is amplified: cotton sops up the little hydration remaining in the epidermis and in your night creams.
Thermoregulation: where silk reacts quickly
A surface that tempers in a few seconds
Cotton takes several minutes to reach body temperature. When going to bed in winter, this cold contact is uncomfortable. Mulberry silk, thanks to its fibrous structure, tempers almost immediately on contact with the skin: no shivers, no unpleasant cold sensation.
Gentle warmth without a stuffy effect
Silk retains body heat without creating a "greenhouse" effect. Natural fibers allow air to circulate, which regulates temperature around the face and scalp throughout the night — without excessive sweating, which would worsen dryness.
Dry and tight skin: the pillowcase's role
Cotton absorbs your night creams
You apply a cream or serum before sleeping. On a cotton pillowcase, part of these active ingredients is absorbed by the fabric. Mulberry silk, which is not very absorbent, keeps your products in contact with the skin longer. In winter, where every treatment counts, the difference is noticeable.
Friction irritates weakened skin
In winter, the skin barrier is weakened. Repeated friction on cotton can accentuate redness and tightness — especially on skin prone to dryness, eczema, or rosacea. The smooth surface of silk reduces this friction, for calmer skin upon waking.
Static, brittle, frizzy hair: the mechanical cause
Dry winter air deprives hair of its natural moisture. On a cotton pillowcase, every nocturnal friction generates static electricity in already dehydrated fibers: this is the direct cause of "bed head" upon waking.
Silk eliminates friction at the source
The smooth surface of mulberry silk allows hair to glide without resistance. Hair fiber is not pulled, and hydration stays in the hair rather than being absorbed by the fabric. In practice: fewer knots, less frizz, less breakage along the lengths.
Curly, coily, and colored hair: the most exposed
Curly and coily hair is more porous, and therefore more sensitive to nocturnal moisture loss — a phenomenon amplified by dry air. Silk helps maintain moisture in the fiber and preserve curl definition without compression. For a detailed comparison, see cotton vs silk for hair.
Which Momme to choose for winter?
Momme measures the density of silk: the higher it is, the denser and more enveloping the pillowcase. In winter:
| Momme | For whom in winter |
|---|---|
| 19 | Discovery, controlled budget. All the properties of silk, lighter drape. Normal to combination skin. |
| 22 | The best balance of density / softness / price. Suitable for the vast majority of profiles. |
| 25 to 30 | Very cold nights, fragile or colored hair, seeking the densest and most durable drape. |
The density details are explained in the Momme guide.
Caring for your silk in winter
Winter does not change the protocol, but requires two precautions:
- Never dry on a radiator. Direct heat weakens the fibers. Dry flat, air dry, away from direct sunlight.
- Wash at 30°C maximum, delicate cycle or hand wash, mild detergent without fabric softener.
- Frequency: every 7 to 10 days; more often if you apply a lot of night creams.
- Two pillowcases in rotation so you never run out during drying.
The complete protocol is detailed in how to wash a silk pillowcase.

Yes, thanks to its thermoregulatory properties. Silk retains warmth around the face and scalp without a stuffy effect, and adjusts to body temperature in a few seconds on contact — unlike cotton, which remains cold for several minutes when you go to bed. For a more enveloping feel, choose 22 or 25 Momme.
It acts on two levels: it doesn't absorb the skin's natural hydration like cotton, and it keeps your night creams in contact with the skin longer. It also reduces friction that irritates a skin barrier weakened by the cold. It's not a medical treatment, but a concrete addition to your routine.
Dry winter air dehydrates hair and makes it more conductive. On cotton, nocturnal friction generates static electricity in already dry fibers. Silk eliminates friction at the source: static electricity no longer has a mechanism to be created.
No. Direct heat weakens the fibers and can alter the fabric's texture. Always dry flat, air dry, in a heated room. Silk dries in a few hours at room temperature, much faster than cotton.
