If the hair is dry, and the air is also very dry, plastic combs (especially nylon) may generate static electricity, and this can result in the hairs standing on end as the charged hair shafts repel each other.
In most circumstances, there is enough moisture in the air, in the hair, or on the hair to keep it combed in place. The low relative humidity in heated interior air during the winter is usually the culprit.

How does a plastic comb and dry hair produce electricity?
When you rub a plastic comb against dry hair, friction causes electrons to transfer from the hair to the comb, giving the comb a negative charge and the hair a positive charge. This separation of charges creates static electricity.
How does a plastic comb and your hair dry produce electricity?
Rubbing the plastic comb against dry hair causes electrons to transfer from the hair to the comb, creating static electricity. The friction between the two materials generates a positive charge on the comb and a negative charge on the hair, resulting in the electricity buildup.
When you comb your hair with a plastic comb what will the sign be on the charge acquired by the comb?
When you comb your hair with a plastic comb, the comb will acquire a negative charge. This is because the friction between the comb and your hair causes the transfer of electrons, leading to an imbalance of negative charge on the comb.
Why does the hair crackles when you comb your hair briskly with a plastic comb?
When you comb your hair briskly with a plastic comb, it can create static electricity. Static electricity occurs when objects with opposite charges rub against each other, resulting in a buildup of electrical charges. This buildup causes hair strands to repel each other, leading to a crackling or popping sound.
How would you demonstrate static electricity with plastic comb dry hair pieces of paper?
To demonstrate static electricity with a plastic comb and dry hair, first rub the comb against the dry hair to create a static charge. Then, bring the charged comb close to small pieces of paper. The paper bits should be attracted to the comb due to the static charge, showcasing the effects of static electricity.
How does a plastic comb and dry hair produce electricity?

How does a plastic comb and your hair dry produce electricity?
Rubbing the plastic comb against dry hair causes electrons to transfer from the hair to the comb, creating static electricity. The friction between the two materials generates a positive charge on the comb and a negative charge on the hair, resulting in the electricity buildup.
What is produced when you rub a plastic comb against your hair?
static electricity

Why is a rice grain tied to a thread is attracted to a plastic comb?
When a plastic comb is charged by rubbing it against a cloth or hair, it becomes negatively charged. The rice grain acquires a positive charge when it comes into contact with the negatively charged comb. Opposite charges attract each other, causing the rice grain to be attracted to the plastic comb.
When a comb rubbed with dry hair why attracts small bits of paper?
When you rub a comb against dry hair, electrons from the hair are transferred to the comb, giving the comb a negative charge. The small bits of paper are attracted to the comb because they acquire a positive charge and are attracted to the negative charge on the comb due to electrostatic forces.
Why does your'e hair stand up when you brush it with a plastic comb?
When you brush your hair with a plastic comb, the friction between the comb and your hair creates static electricity. This static electricity causes your hair strands to repel each other, making them stand up and look frizzy or flyaway. Using a comb made of materials that generate less static, like metal or wood, can help reduce this effect.
What is a Brush?
to comb your hair A brush is an implement with a plastic/wooden handle and bristles that is used to take tangles out of hair.
Why does the comb attract the hair?
When a comb is rubbed against certain materials, such as a piece of fabric or hair, it can transfer electrons from one object to the other. This process creates a static electric charge on both the comb and the hair, causing them to be attracted to each other due to opposite charges.
What force do you use if you comb your hair?
when you comb your hair the force you use is a pull force.
