How to Protect Hair While Sleeping: A Night Routine for Every Hair Type
How to protect hair while sleeping comes down to three things: go to bed with hair that is dry and detangled, keep it gathered loosely so it is not rubbed and pressed under you all night, and hold it with a soft tie that does not pull. The rest is choosing the style that suits your hair length and type, and the surface you sleep on. The checklist and the table below cover both, for straight, wavy, curly and coily hair.
Why hair needs protecting at night
Hair needs protecting at night because a night means hours of movement you do not control. Most people turn over many times while they sleep, and each turn drags the lengths across the pillow. The side you lie on is pressed flat for long stretches, adding up to hours over a night, and a tie that felt comfortable at bedtime keeps pulling at the same spot until morning.
A single night of turning, pressure and pulling does little on its own; it is the repetition, night after night, that adds up.
How to protect hair while sleeping: a bedtime checklist
Rubbing, pressure and pulling are the three things a night routine works on, and how they add up to snapped strands over time is explained in our guide to hair breakage. These six steps apply to every hair type:
- Detangle before bed, gently and from the ends up, so knots do not tighten while you turn.
- Go to bed with dry hair, or at least towel-dry hair that no longer drips; the reasons are set out in our guide to sleeping with wet hair.
- Gather long hair loosely, on top of your head, in a loose braid, or in a low ponytail unless you ever sleep on your back, rather than leaving it spread under you.
- If you wear a tie, choose a soft, wide one without a metal join, and keep it loose enough to hold rather than grip.
- Keep your hairline and fringe free of tension and pressure: no tight bands, clips or pins pressed against the edges overnight.
- Lie on a smooth pillowcase or wear a bonnet, so the lengths have less to catch on as you move.
How to wear your hair to bed, by length and type
The best way to wear your hair to bed depends on its length and type: short hair needs no tie at all, while longer hair is usually gathered loosely so the lengths stay together as you turn.
| Hair | How to wear it to bed | Keep in mind |
|---|---|---|
| Short, above the chin | Loose, nothing to tie | A pressed flat spot in the morning usually settles with a little water |
| Chin to shoulder length | A small loose bun on top, left loose, or a low, loose ponytail at the nape unless you ever sleep on your back | Change the position of the tie from night to night |
| Long and straight | A loose braid, or a loose low ponytail unless you ever sleep on your back | Do not braid tightly, especially at the roots |
| Fine hair | A loose braid or a loose bun on top, with a soft tie | Keep all tension away from the hairline |
| Wavy | A loose pineapple or a loose braid | A braid gives a temporary wave overnight |
| Curly | A loose pineapple or a bonnet | Shorter curls suit several small pineapples |
| Coily, braids, twists, locs | Keep the style and cover it with a bonnet or a loosely tied scarf | Keep the band or knot loose at the edges |
In a pineapple, curls are loosely gathered high on the crown. The method, and what to do with damp curls at bedtime, are covered step by step in our guide to how to sleep with curly hair.
Choosing a hair tie for sleeping
The best hair tie for sleeping is soft, fairly wide and has no metal join, because it stays in place for hours while you move. Fabric-covered scrunchies are wider than a thin elastic, and a scrunchie with fabric all the way round has no hard edge to press into the hair. Put the tie on loosely, at a point you do not lie on, such as high on the crown, or low at the nape unless you also sleep on your back, and move it from night to night so the same spot is not held every time. Which hair ties are gentle on the hair by day as well is covered in our guide to hair ties that do not damage hair.
Leave clips and pins out of your bedtime routine, since they press into the scalp when you lie on them.
What to sleep on
What your pillowcase is made of matters mainly through its surface: the smoother it is, the less the lengths catch on it as you turn. A dense silk weave is smoother than most cotton weaves, which have more texture for hair to snag on. Cotton has its own advantage: it is hard-wearing.
If you would rather keep your hair covered at night, how to choose a bonnet that stays on is set out in our guide to silk bonnet benefits. When you compare labels, remember that satin names a weave, not a fibre; the difference is explained in our guide to silk vs satin.
What a night routine cannot do
A split or snapped strand cannot be restored: care products can only hold a split together or smooth it down for a while, and the lasting fix is to cut it off. A night routine also cannot make your hair grow faster, change your curl pattern or give you more hair. No pillowcase, bonnet or hair tie, silk included, undoes breakage or alters growth or curl pattern. What a night routine can do is stop the night from adding its own share of rubbing, pressure and pulling. If hair is thinning visibly or coming out in handfuls, that is worth seeing a doctor about.
Our silk pillowcases, bonnet and scrunchies
Our silk pillowcases, our silk bonnet and our 10 mm silk scrunchies are all made from organic mulberry silk at 22 momme and Grade 6A, and in each case the silk is GOTS certified. The pillowcases are 100% silk, with silk on both faces and a hidden YKK zip. The bonnet has two layers of silk, inside and out, and closes with an adjustable buckle band over a soft, densely woven elastic edge, 1.5 cm across. The scrunchies are made from the same silk as the pillowcases. All three carry the OEKO-TEX MADE IN GREEN label, and the pillowcase label ID M27MNB1V9 can be checked on the OEKO-TEX website. The pillowcases also carry the Dermatest 5-Star seal and the Dermatest Sensitive Skin seal, dermatologically tested for sensitive skin.
Frequently asked questions
What is the best way to protect your hair while sleeping?
The best way to protect your hair while sleeping is to go to bed with it dry and detangled, gather it loosely so it is not spread under you, hold it with a soft tie that does not pull, and lie on a smooth pillowcase or wear a bonnet.
Should you sleep with your hair up or down?
Long hair is usually better gathered loosely than left down, because loose lengths spread under you and wrap around each other as you turn. Short hair, above the chin, can be left down.
How should I sleep with long hair?
To sleep with long hair, gather it into a loose braid or a loose bun on top, or a loose low ponytail unless you ever sleep on your back, held with a soft tie that sits away from the side you lie on.
What is the best hair tie for sleeping?
The best hair tie for sleeping is soft and fairly wide with no metal join, such as a fabric-covered scrunchie, worn loosely and moved to a different spot from night to night.
How do you wrap your hair at night?
To wrap your hair at night, gather it loosely first, or leave braids, twists and locs as they are, then cover it with a bonnet or a scarf tied loosely at the nape or on top, without the band or knot pressing on your hairline.
Does sleeping on silk protect your hair?
Sleeping on silk gives your hair a smoother surface to lie on, so the lengths have less to catch on as you turn than on a textured cotton weave. It does not replace drying, detangling and a loose, soft tie. A split or snapped strand cannot be restored: care products can only hold a split together or smooth it down for a while, and the lasting fix is to cut it off.
