How to Protect Your Hair While You Sleep
A bedtime routine that keeps hair smoother, less tangled and less likely to break, plus how to choose between a bonnet, a cap, a silk scarf and a silk pillowcase.
Tangles at the nape, flattened curls, a blowout that did not last the night: much of it happens on the pillow.
Protecting your hair at night mostly comes down to friction. Hair that rubs against a cotton pillowcase for hours tangles, frizzes and, over time, breaks. A few habits before bed change that: going to sleep with dry, detangled hair, tying it loosely, covering it, and giving it a smooth surface to rest on. This guide walks through each one, and what to adjust for curly, long, fine or regrowing hair.
the short version
Five habits for before you turn out the light. The order can change with your hair type.
dry itGive your hair time to dry before bed.
detangleA few gentle passes with a wide-tooth comb. Curly or coily hair is easier to detangle wet and conditioned, so do that first.
tie it looselyA loose braid or a soft scrunchie, never a tight elastic.
cover itA satin-lined snood, a satin bonnet or a silk scarf.
sleep on silkA smooth pillowcase means less pulling as you turn over. Use one with a cover or instead of one.
Wearing a cap for warmth or hair loss? Our sleep cap buying guide is the place to start.
why cover your hair at night
what a bonnet or wrap does while you sleep
As you turn over in the night, your hair rubs against the pillow again and again. A cover takes that friction on itself.
- Fewer tangles and less breakage. Hair held on a smooth surface may tangle and break less than loose hair rubbing on cotton.
- Curls hold their shape better. A cover can help curls stay defined overnight, so the morning may start with a refresh instead of a restyle.
- A blowout can last longer. Wrapping smooth hair before bed helps keep it smooth. A little dry shampoo at the roots before you cover it, and you wake up to a refreshed style.
- Overnight treatments stay on your hair. An oil or mask works while you sleep, and a cover keeps it on your hair and off your pillowcase.
- A cleaner pillowcase. A cover can help keep hair oils and styling products off your pillow.
- Gentler on new growth. Hair growing back after chemotherapy is fine and fragile at first, and a soft cover keeps it from rubbing on the pillow while it grows.
Is it bad to cover your head while you sleep? Not with a cover that is soft and fits. The trouble comes from one that is too tight, or one that leaves your scalp itchy and irritated.1 Choose something snug, never tight, and wash it by its care label whenever it feels oily or coated with product.
a bedtime routine for your hair
six steps, and most of them cost nothing
Let it dry first.
Damp hair pressed into a pillow all night wakes up creased, tangled and frizzy. Give it time to dry before bed, even if that means washing earlier in the evening.
Detangle gently.
Work out knots with a wide-tooth comb, starting at the ends and working up to the roots. For curly or coily hair, dermatologists recommend detangling while it is wet and conditioned, so do that in the shower and give it time to dry before bed.3 Tangles that go to bed come out bigger in the morning. The old hundred-strokes-a-night advice is a beauty myth, and a few gentle passes are kinder to hair. Our Deluxe Lift Comb works on your own hair as well as a wig.
Tie it loosely, or not at all.
Tight ponytails and elastic bands pull on your hair all night, and hairstyles that pull over and over can lead to hair loss.2 A loose braid, or a loose ponytail on top of your head held with a soft scrunchie, keeps hair out of the way without the strain.
Treat dry ends if you like.
A few drops of a light oil on the ends, or an overnight mask made for the purpose, works while you sleep. If your scalp is in treatment, ask your care team before trying a new product.
Cover it.
A satin-lined snood, a satin bonnet or a silk scarf tied turban style keeps hair contained and smooth. Which one to choose depends on how much hair you have.
Sleep on silk.
A silk pillowcase gives your head a smooth surface to move on, so there is less pulling on your hair as you turn over. You can use a cover, a pillowcase or both. A pillowcase is the one to choose if you dislike wearing a bonnet or tend to lose it in the night. How to choose one.
go easy on your hair by day, too
The same rule applies when you are awake: styles that pull hard, worn often, can cause a kind of hair loss called traction alopecia.2 Keep daytime styles loose, and change where they sit from day to day. If you want a fuller style without braiding or twisting your own hair, two pieces by Cardani add it for you.
Headband Braid by CardaniThe look of a braid across the crown, without braiding your own hair. An adjustable elastic at the back fits most heads.shop →
Natural Hair Wrap Scrunchie by CardaniA full, messy bun in seconds. It slips over your own bun or ponytail, so keep that one loose and low.shop →
Take them off at night, the same as a wig.
bonnet, cap or scarf?
choose by how much hair you have
All of these protect your hair. They differ in shape, in how much hair they hold, and in whether you would wear them out of the house. If you have hair and are not sure where to start, start with our Satin Lined Slouchy Snood by Cardani: satin against your hair, and a slouchy snood shape that holds it without crushing it.
| best for | good to know | |
|---|---|---|
| satin-lined snood | Anyone with hair. Our first choice for protecting hair overnight. | Satin inside, a slouchy snood outside that holds hair without crushing it. |
| satin bonnet | Long, thick or curly hair, braids and twists. | The roomiest choice, so nothing is crushed. Satin against the hair keeps friction down. |
| silk scarf | Smooth styles and blowouts, and hair you want to keep in place. | Tie it turban style. It doubles as daytime wear, and it is one of the most popular things women with hair buy from us. |
| roomy sleep cap | Shorter hair, or a cap you can also lounge in. | Keeps hair contained. Pair it with a silk pillowcase for smoothness. |
our picks for anyone with hair

Ribbon Satin Sleep BonnetRoomy on top for long, thick or curly hair, with a covered elastic at the hairline. Fully lined in satin.shop →
The Satin Lined Slouchy Snood by Cardani has a satin lining against your hair and a soft viscose from bamboo outside. It is roomy enough for long or full hair, and an interior drawstring lets you adjust the fit. It works on short hair, thinning hair and new growth too. If your hair is long, thick or curly, the Ribbon Satin Sleep Bonnet gives it more room, with a covered elastic at the hairline to hold it in place.
wrapping your hair in a scarf or turban
A silk head scarf tied turban style is the classic hair wrap for sleeping, and protecting hair at night is one of the most popular uses for our 100% silk scarves. Gather your hair loosely at the crown or let it lie flat, wrap the scarf around your head from the nape, and tie or tuck the ends at the front. Our guide to tying a head scarf shows the turban tie step by step.

100% Silk Head ScarfThe same 36-inch square in prints, and it comes with tying instructions.shop →
Prefer not to tie anything at bedtime? A ready-made turban or a pre-shaped head wrap slips on in seconds. Choose a smooth, soft fabric, and keep anything with a stiff seam or knot at the back for daytime.
sleeping on silk
how to choose a silk pillowcase
A silk pillowcase gives hair a smooth surface to slide over, so there is less tugging as you turn. It protects your hair even on the nights the bonnet comes off, and because a pillowcase lies against your face all night, silk is the fabric to choose for it.
three things to look for
- Mulberry silk. Look for 100% mulberry silk on the label. It is generally considered the highest quality silk.
- The momme weight. Momme (written mm) measures the weight of the silk fabric. A 22 momme pillowcase has more substantial fabric than a comparable 16 momme one. Look for at least 16, and 22 if you can.
- Compare what you are paying for. Compare fiber content, momme weight, construction and care instructions rather than price alone.
Our Cardani Silk Pillowcase is 100% mulberry silk at 22 momme. We have slept on it, washed it and tested it thoroughly.
silk or satin? how to tell them apart
The two look alike, are often sold side by side, and confuse a lot of people. Silk is a natural fiber. Satin is a weave, a way of making fabric smooth and glossy on one side. When a label says satin, it is almost always a synthetic such as polyester. A silk product will say silk.
| silk | satin | |
|---|---|---|
| what it is | A natural fiber, spun by silkworms. | A weave. Labeled satin, it is almost always polyester. |
| what the label says | 100% silk or mulberry silk, often with a momme weight. | Satin, polyester, or words like silky and silk feel. |
| moisture and heat | A natural fiber that takes up moisture the way cotton does, so it breathes and stays comfortable through the night. | Takes up little moisture, so it does its best work against hair, as a bonnet lining, with a breathable fabric outside. |
| price | Costs noticeably more. | Costs less. |
| care | Gentle washing, by the care label. | Easy to wash, and holds up well to nightly wear and washing. Follow the care label. |
| most often used for | Pillowcases and scarves. | Bonnets and cap linings. |
Both give hair a smooth surface, and both reduce friction. A few words cause most of the confusion:
- Silk satin, or silk charmeuse, is silk woven as satin. It is real silk, and the label will say silk.
- Silky, silk feel, silk touch or luxury satin describe how a fabric feels, not what it is made of. None of them means silk.
- Satin silk on a label with no fiber content is a warning sign. Look for the fiber, and if it does not say silk, it is not silk.
Each has its place. Satin is smooth against hair, easy to wash and holds up well to being worn every night, which is why it lines most bonnets, including our Satin Lined Slouchy Snood, where satin sits against your hair and breathable viscose from bamboo sits outside. Silk is the finer fabric: a natural fiber that breathes and feels soft against skin, so it is the one to choose for what lies against your face all night, like a pillowcase, and for a scarf. If you run warm, or have the hot flashes and night sweats that can come with treatment, that is where silk makes the most difference.
by hair type
small changes that suit your hair
curly and coily hair
Curly and coily hair tends to be drier and more prone to breakage than straight hair.3 A loose pineapple on top of the head, or twists, under a roomy satin bonnet keeps curls defined and saves you a morning of detangling. Choose a bonnet big enough that nothing is squashed. Our guide to hair loss in African American women covers gentle styling in more depth.
long hair
Long hair tangles most at the nape, where it rubs against the pillow. A loose braid, or hair piled loosely on top of the head and held with a soft scrunchie, keeps it out from under you. Tuck the ends into a bonnet or wrap so none of it is left loose.
fine or thinning hair
Fine hair breaks easily, so be gentle at every step: detangle from the ends up, avoid tight or uncovered elastics, and sleep on silk. A satin-lined snood keeps fine hair contained, and its drawstring lets you set the fit. If you are losing more hair than usual, our guide Help! My Hair Is Falling Out! explains the common causes.
hair growing back after chemo
New hair after chemotherapy is very fine at first, and it may come in curlier, straighter or a different color than before.4 If you find a soft cap comfortable, you can keep wearing one while it grows. A cap in cotton or viscose from bamboo is gentle on new growth, and our guide to hair growth after chemo covers what to expect month by month.
common questions
open only the one you need
is it bad to cover your head while sleeping?
Not with a soft cover that fits. Dermatologists at Cleveland Clinic note that the risk comes from headwear that is too tight, or that leaves the scalp itchy and inflamed.1 Choose a bonnet, cap or scarf that sits snug without pressing, and wash it often.
does covering your hair make it grow?
No. An ordinary bonnet or sleep cap does not change how fast your hair grows, because hair grows from the follicle under the skin. What a cover can do is help cut down on breakage, so more of the length you grow stays on your head.
why do people wear bonnets to bed?
To protect their hair. A satin bonnet holds hair in one place and gives it a smooth surface instead of a cotton pillowcase, which can mean less tangling and frizz and a style that lasts longer. Bonnets are especially popular for curly and coily hair, braids and twists.
is it better to sleep with your hair up or down?
Loosely up, for most people. A loose braid or a loose ponytail on top of the head keeps hair from tangling underneath you. The key word is loose: a tight ponytail or elastic pulls on the hair all night.
is it bad to sleep with wet hair?
It is hard on your hair. Wet hair pressed into a pillow dries creased and tangled, and it is weaker and stretches more easily while it is wet. Give it time to dry before bed.
should you wear a headband to sleep?
A soft, wide band is fine for keeping hair off your face. Skip anything tight, or a hard headband that presses behind the ears. A bonnet or a silk scarf does the same job and protects the rest of your hair too.
is silk or satin better for your hair?
Each has its place, and both are smoother than cotton. Satin is smooth against hair and holds up well to nightly wear and washing, which makes it the everyday choice for a bonnet lining. Silk is a natural fiber that breathes, so it is the better choice for a pillowcase or a scarf, especially if you run warm. When a label says satin, it is almost always polyester. A silk product will say silk. Follow the care label when you wash either one.
how can I tell if a pillowcase or bonnet is real silk?
Read the fiber content on the label. Real silk says 100% silk or mulberry silk, and a silk pillowcase usually gives a momme weight too. If the label says satin, polyester, or only describes the feel with words like silky or silk feel, it is not silk. More on silk and satin.
