Why Nylon and Plastic Comb Gets Electrified

Friction between Comb and Dry Hair
When you comb dry hair with a nylon or plastic comb, there is friction between the comb and the hair. This friction causes the transfer of electrons between the two surfaces.

Triboelectric Effect
The phenomenon of static electricity generation due to friction is known as the triboelectric effect. When two materials rub against each other, electrons can transfer from one material to the other, leading to an accumulation of either positive or negative charge.

Nylon and Plastic are Insulators
Nylon and plastic are both insulating materials, meaning they do not conduct electricity easily. When these materials rub against dry hair, the transfer of electrons can build up on the comb, creating a static charge.

Charge Imbalance
As you continue to comb your hair, the static charge on the comb increases due to the constant friction and electron transfer. This charge imbalance results in the comb becoming electrified.

Preventing Static Electricity
To reduce static electricity when combing dry hair, you can use a metal comb or apply a small amount of hair oil or conditioner to your hair before combing. These methods can help to dissipate the static charge and prevent your comb from becoming electrified.
