Preserves your style, protects your hair — a silk ritual for softer mornings.
Zijden slaapkapje
Overnight protection for smoother, softer, healthier hair.
De ZILK zijden haarkap is ontworpen om je gezondste haar te ondersteunen terwijl je rust. Gemaakt van 100% met zilverionen verrijkte moerbeizijde en dubbel gevoerd aan de binnen- en buitenkant, helpt het om wrijving te verminderen, vocht vast te houden en je haar 's ochtends gladder te stylen.
De zachte stretchband sluit perfect aan op uw hoofd, zonder te verschuiven of te trekken. Hierdoor blijft uw muts de hele nacht op zijn plek, van diepe slaap tot ontspannen ochtendritjes.
ZACHTE HAARBESCHERMING
Vermindert wrijving die kan leiden tot pluizig, brekend en gespleten haarpunten, zodat het haar gladder en beter handelbaar wordt.
VOCHTBEHOUD
Zijde neemt geen leave-in producten of natuurlijke oliën op zoals katoen. Het helpt hydratatie, verzorgingsproducten en krulcrèmes te behouden waar ze horen: in je haar.
STIJLBEHOUD
Helpt föhnen, krullen, vlechten en beschermende kapsels langer mooi te houden, zodat ze er langer fris uitzien en minder dagelijkse hitte of manipulatie nodig hebben.
KOELEND + ADEMEND
Zijde heeft een natuurlijk warmteregulerend effect, waardoor uw hoofdhuid de hele nacht comfortabeler aanvoelt en minder zweterig is.
SCHONER SLAAPOPPERVLAK
Zilverioneninfusie helpt bacteriën en geurtjes te bestrijden, zodat uw kap frisser blijft tussen wasbeurten door.
Why Silk Matters for Hair
Hair moves while you sleep, causing friction that leads to frizz, dryness, and breakage. The ZILK Silk Sleep Bonnet surrounds every strand in smooth, 25-momme Mulberry silk to reduce friction, lock in moisture, and keep styles intact. You wake up with softer, stronger, more manageable hair.
What Makes 25 Momme Exceptional
Many silk bonnets use lighter silk that thins out or loses its sheen. ZILK uses 25-momme 6A Mulberry silk inside and out which means a denser weave, more uniform threads and a smoother surface that is built to last. The result is a bonnet that keeps delivering hair benefits night after night.
The Clean Sleep SurfaceZILK silk is infused with silver ions which help resist the growth of bacteria and odor on the fabric. This keeps your bonnet feeling fresher between washes and supports a cleaner sleep environment for your scalp and hair.
Silk is naturally hypoallergenic, making the ZILK Sleep Bonnet gentle on sensitive scalps and suitable for anyone prone to irritation or dryness. Unlike synthetics, it resists dust and buildup that can weigh hair down. The breathable 25-momme weave helps regulate temperature and wick away moisture, so your scalp stays cool and comfortable through the night — never sweaty or constricted.

The Science of Calm
NeuroSilk™ Technology for Mind–Body Restoration
Rest isn’t only about time spent sleeping, it’s about creating the conditions where your body and mind can let go.
ZILK’s NeuroSilk™ technology is inspired by the science of psychodermatology and neurocosmetics—fields that explore how emotions, stress and skin are connected. The goal is simple: support the brain and body as they shift into a calmer state.
Calming Sensory Cues: ZILK’s smooth, cooling sensation activates relaxation responses, signaling to your nervous system that it’s safe to slow down.
Less Friction, More Flow: When your skin and hair glide instead of tugging, it’s a small but powerful signal of ease.
Cleaner Rest, Clearer Mind: Silver ion infusion helps resist bacteria and odor, so your sleep surface feels fresher — reinforcing the ritual of calm.
Frequently Asked Questions
Why use a silk bonnet instead of a cotton scarf or pillowcase alone?
Silk creates less friction than cotton and does not pull moisture or treatments from your hair. A bonnet offers 360-degree coverage so your lengths and ends stay protected even if you move around at night.
Is the ZILK silk bonnet good for curly and coily hair?
Yes. It is especially helpful for curls and coils because it helps preserve definition, reduce frizz and keep styles looking fresher between wash days.
Can I wear the bonnet with protective styles or extensions?
Yes. The full-coverage design is ideal for braids, twists, sew-ins and other protective styles. It helps reduce friction on your lengths and your edges.
Will the bonnet feel too hot?
Silk is naturally breathable and thermo-regulating so it feels cooler and more comfortable than many synthetic or heavy fabrics. If you tend to sleep warm, silk is a great option.
How often should I wash my silk bonnet?
This depends on your hair and product use. As a general guide, wash every 1–2 weeks or more often if you use heavy oils or styling products.
Does one size really fit most?
The bonnet is designed with a soft stretch band that comfortably fits most head sizes from approximately 54 to 72 cm. If you find most standard beanies or hats fit you, the bonnet should fit as well.
