Mulberry Silk Hair Bonnet | Smoother, Healthier Hair Overnight

Ritual of Restoration

SMOOTHER NIGHTS, CLEANER SLEEP

Sleep is a big part of how skin and hair recover. Whatever ZILK piece you sleep on, the fabric is the same: 25-momme mulberry silk infused with SILVADUR silver ions. Smooth enough to glide against skin and hair, and clean enough to stay fresh between washes.

INSIDE EVERY ZILK PIECE

Silver Ion Technology

Every ZILK Sleep product is infused with SILVADUR, DuPont's patented silver-ion treatment that helps keep fabric cleaner between washes while staying gentle on skin.

99.9% bacteria growth inhibition, based on SILVADUR testing
Fresher fabric, wash after wash
OEKO-TEX® certified for tested safety in textile chemistry

ENGINEERED FOR ENDURANCE

25 MOMME SILK

Momme measures silk's weight and density. At 25-momme, the weave is tighter, the surface is smoother and the fabric holds its performance significantly longer than the 19-23 momme silk used by most brands. It's the difference between silk that feels good now and silk that keeps working for years.

high GRADE MULBERRY SILK

6A Silk Quality

ZILK Sleep uses only 6A grade mulberry silk, woven from the longest, most uniform fibers available. The result is exceptional softness, resistance to pilling and a surface that glides against skin and hair rather than catching on it.

NeuroSilk™ Technology

The Science Behind the Feel

NeuroSilk™ is ZILK Sleep's proprietary silk technology, rooted in neurocosmetics: the science of how sensory experience affects skin, stress and sleep quality. The cool, smooth surface of mulberry silk is designed to create the physical conditions for rest, a quieter, lower-friction surface than what most people sleep on.

Cool, smooth contact against skin through the night
Less friction means less pulling on skin and hair overnight
SILVADUR silver ions keep the surface fresher between washes

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.
