What is static hair?
To explain what static hair really is, we have to make use of slightly nerdy descriptions. Perhaps you learned at school that everything basically consists of atoms and that these atoms then consist of protons, neutrons and electrons. Hang in there, because now it's getting a little technical. Electrons are negatively electrically charged and if these electrons then escape from the atom and settle on another atom, suddenly there are 2 negatively charged electrons in the same atom. This will result in them repelling each other. And it is actually this reaction that causes static hair.
To elaborate, when the hair receives a lot of extra negatively charged electrons, which causes electrical charges to arise in the hair, it will cause the individual strands of hair to repel each other. Just like if you put two negative ends of a magnet against each other. This will cause your hair to fly around on your head or, for example, will stick to your skin or your clothes.
The difference between static hair and frizzy hair
Static hair is caused by static electricity, which causes hair to stand out and become flyaway. This often happens in dry environments or in winter. Static electricity is caused by a lack of moisture, which causes the hair to become electrically charged. In colder months, the combination of low humidity and indoor heating can lead to a higher chance of static buildup, as the air pulls moisture from your hair. To tame static hair, use anti-static sprays, moisturizing products and avoid synthetic materials, that can increase static buildup.
Frizzy hair occurs when hair lacks moisture in its outer layer (cuticle), causing the hair to absorb moisture from the environment and swell. This leads to a coarser texture and uncontrolled volume. Frizzy hair is often the result of damage from hot styling tools, chemical treatments or natural hair texture. Additionally, humid weather can cause frizz-prone hair to swell more easily, as the hair absorbs excess moisture from the air. To combat frizz, you can use moisturizing shampoos and conditioners, leave-in conditioners and anti-frizz serums or oils. Using a microfiber towel to dry hair and minimizing heat styling can also reduce frizz.
Why is my hair staticky?
But how does your hair suddenly become static? Why and how does your hair pick up these electrons?
Static hair occurs when there is friction between your hair and another object. Have you tried the trick of rubbing a balloon against your hair? It is actually the same thing that happens when you, for example, use hats, scarves or the like. The friction that is created means that the negative charge of electrons rubs off on your hair and creates this electrical charge. This effect is even more noticeable when hair is dry, as moisture helps to balance electrical charges. With less moisture, hair is more susceptible to static buildup.
Now you may be asking why you rarely have static hair in the summer but you constantly have it in the winter?
There is a good explanation for that. In the summer, the weather and humidity are usually high, this means that the electrical charges become more spread out and therefore have an easier time being discharged. On the other hand, winter is often characterized by low humidity. This lack of moisture in the air makes it easier for static to build up, as dry air acts as an insulator, allowing the static charge to linger longer in the hair.
The dry climate together with dry hair creates the best conditions for static hair. In particular, the changing climate between the cold air outside and the warm air inside helps to create the optimal conditions for static hair. If the hair is dry or damaged you will be able to experience a greater degree of static hair.
Why is my hair staticky, when I brush it?
When you brush your hair, friction is created between the brush and hair strands, which transfers electrons and builds up static electricity. This effect is often stronger with plastic or metal brushes, as they increase the electrical charge in your hair. To reduce static, try using a natural bristle brush and brushing slowly to minimize friction.
