You should wash your hair every week if you have thick hair and you don't always put oils in your hair. UNLESS you have thin hair. You should wash your hair hair every other day!
Wear something comfortable on field day e.g if you are wearing jeans make sure it is not very tight. Wear some t-shirt rather than a dress shirt. If you are a girl tie your hair in a ponytail. Both genders can wear a cap if they want.

You can wash it everyday but one every other day you should shampoo your hair because your hair needs some oil too.
Every other day should be enough
Every Day
