It looks like it could be Alopecia. Ask your parents to take you to a Dermatologist to find out what's going on.

An underactive thyroid gland often causes this kind of hair loss. When treated, the hair grows back. Your are correct, your condition is not related to the baldness gene.

It is probably alopecia or hypothyroidism. I doesn't sound like male-pattern baldness.
