Suggest Remedy To Get Rid Of Bald Spot In Head

I have a bald spot on the top of my head. I am only 14 years old and had just realized it a few minutes ago. I know it wasn't there this morning and it is the only spot that is bald. Its about the size of a quater and I have already told both of my parents. They both said to look it up and they will consult a doctor. Im too impatient to wait for a doctor right now. Please help.
