Hairbrush


Over the years, I've realized that when I brush my hair, it gets "staticy" and won't stay flat for a while. Sometimes, the same thing happens at school when I am sitting in a chair with my hair against the back of my chair. This is because when I rub my hair against something like a hairbrush or a chair, each hair has the same charge and like charges repel. I used to get really annoyed when my hair would not stay flat. However, I found an ionic brush that reduces the static electric forces when I am brushing my hair. The ionic brush somehow maintains the balance of opposite charges in my hair so that hairs of opposite charges attract each other and my hair stays flat. Brushing long hair can be a pain sometimes, especially if it's really tangled, because you have to exert more force to undo the knots.
