Explain how hair is an example of personal expression

You express yourself by the way you style you hair, cut you hair, or what you put in your hair. Some people like curly hair, so they curl it. Some people like wavy hair, so they make it wavy. Some people like straight hair, so they straighten it.

Many people express themselves through their hair. They can braid it, cut it, leave it down or color it based on their style and the type of person they are. Some choose to dye it bright colors or shave their hair completely. No one can tell them what to do with their hair.
