So what can you do when your hair starts buzzing and you're not at home. Use a metal comb. Hairbrushes create more friction in your hair, so ditch that idea. However, combs that are made of plastic can contribute to causing static, while metal combs actually reduce the amount of static present in your hair. When you use a metal comb it causes the electric charges building in your hair to discharge!
PS. a little tip: Static electricity is what causes static cling in clothing. Diffuse the static by pinning a safety pin to an inside seam of the item. Once again, the positive charge of the metal pin will attract the negative charge of the clothing and good-bye static!
