Bald Spots on 6 Year Old

My 6 year old son has developed bald patches in his head. It began with one bald spot this summer and then traveled to the opposite side of his head. So now there are two bald spots. Now it looks as another bald spot is forming on top of one of the other spots. We have taken them to him to the dermatologist and they stated that is was nothing to worry about. They tested the spots and informed us that no fungus was located and that the patches should fill in on there own. I don’t see any impovement and want to that him to another dermatologist.

Do you have any idea what this could be and could you provide some suggestions.

Thanks in advance

I have addressed this type of question a few times before (search for “child”). There are many causes of hair loss including fungal and bacterial infections. In children, fungal infections are not uncommon. The presence of conditions such as alopecia areata are amongst the many possibilities, but if it just goes away as your doctor said, then waiting sounds like the thing to do. Most of these conditions are not life threatening. I wish I had more advice to give, but without seeing the child, it would be very hard to try to come to a conclusion over the internet.
