Static Hair: Why It Happens and How to Keep It Down
Static hair is hair whose strands pick up an electric charge when they rub against something and then separate, so the charged strands push each other apart and stand away from the rest of your hair. It shows up most in dry indoor air, after pulling off a hat or jumper, or after brushing dry hair. Keeping friction low and keeping both your hair and the air from getting too dry are what keep static hair down day to day.
What causes static hair
Static hair starts with contact. When two surfaces touch and then pull apart, a small amount of electric charge moves from one to the other, and a hat, a brush, a scarf or a pillowcase can each leave your hair carrying a charge. Hairs that carry the same charge repel each other, which is why single strands lift and fan out instead of lying together. In humid air the charge drains away quickly; in dry air it stays on the hair long enough for you to see it, and sometimes to hear a faint crackle.
Why static hair is worse in winter
Static hair is worse in winter because heated indoor air is dry, and dry air lets a charge build up and stay on the hair instead of draining away. Wool hats, scarves and jumpers come out in the same months and add more contact and separation. A humidifier raises the humidity in a room, and hair in a less dry room tends to hold less charge.
How to get rid of static hair quickly
Static hair settles fastest when you give the charge something to drain into and stop adding friction.
- Dampen your palms lightly with water and smooth them over the flyaway areas, without soaking the hair.
- Work a little leave-in conditioner between your palms and press it onto the ends that stand up most.
- Stop brushing: every stroke through dry, charged hair adds friction and more charge.
- If you have to tidy the hair, use your fingers or a wide-tooth comb and move slowly.
How to prevent static hair
Preventing static hair comes down to less rubbing and less dryness, spread across the things you already do each day.
Condition the lengths
Conditioner on the lengths and ends leaves them smoother, so strands slide past each other and past whatever they touch instead of catching. Leave the roots out if your hair gets flat quickly.
Brush less, and gently
Brushing is contact followed by separation, over and over. Brush only as much as you need to, and detangle from the ends upwards. On dry, fine hair, use a wide-tooth comb or your fingers and move slowly. If your hair feels dry all the time, our guide on how to fix dry hair covers the causes and what to do about it.
Dry without rubbing
Squeeze water out with a towel instead of rubbing it back and forth, and let the hair dry partly in the air before you use a dryer. Hair that is blow-dried until it feels very dry holds little moisture, and a charge stays on it longer.
Watch what your hair rubs against
Hats, scarves, jumpers and bedding all touch your hair for long stretches. How much static you notice depends on the humidity in the room, on the weave and the finish, on what the fabric rubs against, and on how much moisture the fibres themselves hold. The fabrics used for pillowcases are compared feature by feature in our guide to silk vs satin.
Keep the air from getting too dry
In winter, drying laundry indoors or running a humidifier both raise indoor humidity. Neither is a cure on its own, but together they make dry air a smaller part of the problem.
Static hair at night
At night your hair touches and leaves the pillowcase every time you turn your head, so the pillow is one more place where contact and separation happen for hours. A smooth pillowcase gives the hair less to rub against than a rougher weave, which keeps friction low overnight. Gathering long hair loosely on top of the head also keeps the lengths from being dragged under you. If your pillowcase is silk, the terms on its label are explained in our guide to mulberry silk.
Static hair and frizz
Static is one of the things that set off frizz, alongside humidity and mechanical stress, so the two often turn up together. Frizz has other causes too, and they are covered in our guide to frizzy hair. When the flyaways appear mainly in dry indoor air and settle as soon as you touch them with damp hands, static is the likelier cause. Hair that looks untidy in the morning for a different reason, such as a flat side from the pillow, is explained cause by cause in our guide on how to avoid bed head.
When static comes with dry, rough ends
Ends that feel dry and rough stand away more easily, catch on each other and tangle. Their rough surface also scatters light, which is why worn ends often look dull, as our guide on how to get shiny hair explains. Brushing them while they are charged pulls on strands that are already under strain. If static comes with ends that snap or look frayed, gentler handling matters more than any single fix. How to tell breakage from hair loss, and what causes it, is explained in our guide to hair breakage.
Our silk bonnet and pillowcases
Our silk bonnet and pillowcases are both 22 momme Grade 6A organic mulberry silk. The bonnet has two layers of it, silk inside and out, and closes with an adjustable buckle band over a soft, densely woven elastic edge, 1.5 cm across. Its silk is GOTS certified, and the bonnet carries the OEKO-TEX MADE IN GREEN label. Our silk pillowcases are 100% organic mulberry silk with silk on both faces and a hidden YKK zip. Their silk is GOTS certified as well, and the pillowcases carry the OEKO-TEX MADE IN GREEN label under the label ID M27MNB1V9, which can be checked on the OEKO-TEX website. The pillowcases carry the Dermatest 5-Star seal and the Dermatest Sensitive Skin seal, dermatologically tested for sensitive skin.
Frequently asked questions
Why is my hair so static?
Your hair is static because it has picked up an electric charge from rubbing against something, such as a hat, a brush or a pillowcase, and the air around it is too dry for the charge to drain away, so the charged strands repel each other.
How do you get rid of static hair quickly?
To get rid of static hair quickly, smooth it with lightly dampened palms, press a little leave-in conditioner onto the ends that stand up, and stop brushing, because every stroke through dry hair adds more charge.
Why is static hair worse in winter?
Static hair is worse in winter because heated indoor air is dry, so a charge stays on the hair instead of draining away, and wool hats, scarves and jumpers add more contact.
Does a silk pillowcase help with static hair?
A silk pillowcase gives your hair a smoother surface than a rougher weave, so there is less friction at night. How much static you notice still depends on the humidity of the air in the room and on everything else your hair rubs against during the day.
Is static hair a sign of damage?
Static hair on its own is not a sign of damage: it shows up on healthy hair in dry air. Ends that also feel rough, tangle easily or snap are worth handling more gently.
Can a hat make hair static?
Yes, a hat can make hair static, because pulling it off separates two surfaces that have been rubbing together, which leaves a charge on the hair. Smoothing your hair with damp palms after you take the hat off helps it settle.
