Static hair: why and how to tame it

What you must remember

Static hair results from a transfer of charges between two rubbing surfaces, which dry air prevents from dissipating. But under equal conditions, it is the state of the hair fiber that decides: a weakened cuticle retains the charges, an intact cuticle allows them to flow away.

  • Static electricity comes from friction, which dry air prevents from dissipating.
  • A porous fiber retains charges, a healthy fiber allows them to flow away.
  • A wash at pH 5 limits swelling and lifting of the scales
  • Satin and natural fibers eliminate the source of friction

Your hair stands on end, clings to your sweater, and refuses to be styled as soon as the air becomes dry. Static electricity is no mystery: it's a transfer of charge between two surfaces rubbing together. What makes all the difference, however, is the condition of the hair fiber—an intact cuticle dissipates the charge, while a damaged cuticle retains it.

Why do hairs become static?

When your hair rubs against a hat, sweater, or brush, electrons transfer from one surface to the other. The strands then become charged with the same sign and repel each other—hence the effect of hair floating. Dry air exacerbates this phenomenon: without water vapor to disperse the charges, they accumulate instead of flowing away.

  • Synthetic materials, primarily wool and polyester, contribute the most
  • The dry air of winter and the heating system prevent the gases from escaping.
  • Dry brushing tangled hair increases friction.


Everyone talks about cold and humidity, but no one talks about the hair fiber. Yet, two people in the same room don't have the same problem: the one with an intact cuticle dissipates the charges, while the one with a raised cuticle retains them. Dry air is the trigger; the condition of the hair is the real variable.

Why is some hair more static than others?

Because a healthy hair fiber conducts charge better than a damaged one. Porous hair , whose surface lipid film has been depleted by coloring, heat, or overly alkaline washing, retains water less effectively—and water is precisely what allows charge to flow. Fine, lighter hair also lifts more easily under the same charge.

Tips to reduce static hair

These reflexes are enough to get through the winter without daily struggles:

  • Double hats and scarves with satin or silk to eliminate friction from the wool.
  • Opt for natural fibers over synthetic materials, especially polyester.
  • Humidifying the indoor air, a bowl of water on the radiator is enough to make a difference
  • Detangle on damp hair and conditioning treatments, never dry
  • Choose a wooden comb or a brush with natural bristles rather than a cheap plastic one.
  • Apply a leave-in conditioner to the lengths of your hair before going out

Verified review

"Incredible! I didn't really believe it, but it's true: by taking care of the roots, the ends follow. My hair is shiny, nourished, and the application is super easy. Very, very good product."

The protocol for hair that no longer gets static

These tips provide relief, but they don't address the root cause. Hair that retains moisture properly doesn't accumulate much. Exfoliate your scalp to expose the roots, wash at pH 5 to minimize swelling and cuticle lift, and nourish the lengths to replenish the surface lipid film. It's this film, not an anti-static spray, that makes all the difference in January.

F.A.Q

Why is my hair static in winter?
Because cold air and heating contain little water vapor. Without it, the charges generated by the friction of hats and sweaters do not dissipate and accumulate on the hair, which then repel each other.
How to remove static electricity from hair quickly?
Run slightly damp hands through the lengths of your hair, or apply a small amount of leave-in conditioner: the water and lipids will disperse the fillers immediately. Slowly running a wooden comb through your hair will also help loosen the strands.
Are static hairs a sign of damaged hair?
Often, yes. Hair fibers with a depleted lipid film retain water less effectively and become saturated more easily. If your hair becomes statically charged with the slightest friction all year round, it's a sign of high porosity.
Which shampoo should I use to combat static hair?
A shampoo with a pH of 5, sulfate-free. A shampoo that's too alkaline makes the hair fiber swell and lifts the cuticles, which directly increases static electricity. The pH of the shampoo matters more than any anti-frizz product.
Does a wooden comb really prevent static electricity?
It helps because it generates less charge than plastic. But it doesn't correct a fiber that doesn't retain water well: it's a good complement, not a solution on its own.
