What causes static electricity?

How do you keep from getting shocked and having static make your hair flyaway?

An atom is made up of neutrons and positively-charged protons surrounded by negatively-charged electrons. When two objects come into contact, electrons are exchanged. Especially if the objects are not identical, one gives up more electrons than the other and becomes positively charged. The other receives more electrons and becomes negatively charged. This action is accelerated if the objects are rubbed together (essentially creating more contact).

If the object with a net gain of electrons is a good conductor – such as copper or steel – then the new electrons will dissipate rapidly. However, if that object is an insulator – such as your hair or a sweater – then the electrons will build up on the surface. When they come into contact with a good conductor, such as a doorknob – ZAP!

Fly-away hair is usually a result of electrons being given up to your hairbrush. You may remember from your science classes that like charges tend to repel one another; your hair strands are trying to do the same thing!

Static electricity tends to be more of a problem in the winter, when the air and surfaces have a lower moisture content. If you don’t want fly-away hair, I’m afraid the best solution is to make sure your hair is wet!

One of the obvious answers to the static shocks is to purchase a good humidifier to increase the moisture in the room, also don't shuffle leather soled shoes on a carpeted floor.
