  • Zero compression: No tight elastic, no marks, no knots. Your long hair is contained without excessive pressure all night long.

The press is talking about silk

Silk, hypoallergenic and antibacterial, is recommended for sensitive, reactive or acne-prone skin, to avoid irritation caused by repeated friction.

— Marie Claire

Silk doesn't absorb night creams and lets skincare do its work. On waking, skin is more radiant, fresh and crease-free.

— ELLE

They can't do without it any more.

"It's a real investment in beauty and comfort.
I'd highly recommend it to anyone who wants
to improve the quality of their sleep and look after
their hair and skin.
It's a bedroom must-have!"

Hand holding a powder pink mulberry silk bonnet

Your hair, protected until morning.

Every night, your hair rubs against the cotton of your pillow. It absorbs its moisture, snags the fibre, and by morning you have to start all over again. The mulberry silk bonnet creates a smooth surface all around your hair: your lengths glide instead of catching.

Less breakage at the ends, less frizz, a style that lasts. Your curls stay defined and radiant all night long. When you wake up, save up to 10 minutes every morning.

Recommended by dermatologists: sleeping in a silk bonnet helps reduce friction and protect your hair.

Sleep on it for 100 nights: we're convinced you won't be able to do without it. The difference in your hair and skin shows from the very first nights.

We answer your questions

The bonnet we're asked for most, and the answers to the questions that come up before buying.

What is a silk bonnet really for?

At night, your hair rubs against the cotton of your pillowcase, which absorbs moisture and snags the fibre. The bonnet creates a smooth surface around your hair: less friction, less breakage, and a style that lasts longer after you wake up.

Does it stay on all night or does it slip?

The edge is elasticated and lined, so it holds snugly without marking your forehead. With very voluminous hair, tuck your lengths inside before putting it on: it's the weight of loose hair that makes a bonnet fall off, not the elastic.

Is it suitable for my hair type?

Yes, from fine, straight hair to 4C coily hair. Curly and wavy hair gains definition, coily hair gains moisture, and long hair sees less breakage at the ends. Short hair benefits most from the zero-frizz effect in the morning.

Silk or satin, what's the difference?

Satin is a weave, not a material: most satin bonnets are made of polyester. It glides, but it doesn't breathe and makes your scalp sweat. Mulberry silk is a natural, thermoregulating fibre that absorbs very little moisture from your hair and your treatments.

Is 19 momme enough?

Momme measures the density of silk. For a bonnet, 19 momme is the right balance: dense enough to be opaque and durable, supple enough to stay light on your head all night. Above that, you gain thickness without gaining comfort.

Can I wear it on wet hair or with a treatment?

On damp hair yes, on soaking wet hair no: the water stays trapped and your scalp doesn't dry. With a mask or an oil, let the treatment sink in for a few minutes, then put the bonnet on, and wash it more often.

How do I wash it without damaging it?

By hand, in cold water, with a gentle detergent free from enzymes and bleaching agents. Press without wringing, and dry flat away from any heat source. In the machine, use a laundry bag and a delicate programme at 30°C maximum. No tumble dryer, no fabric softener.

How long does it last?

Several years with hand washing. If you wear it every night, allow for one wash a week, and ideally have a second bonnet so the first can dry completely.

Where does your silk come from?

Mulberry silk certified OEKO TEX Standard 100, selected by us and checked before dispatch. We are a French brand: customer service and dispatch are handled from France.

What if it doesn't suit me?

You have 100 nights to try it. If it doesn't suit you, write to us and we'll arrange the return.
