My natural hair isn't actually mine?

I have curly hair, but my mom has straight hair, my dad has some wavy hair, but not curly. I never had any siblings, so my hair was always the odd one out in the family. I've always wondered, because of this, who I got my hair from? There are no curly haired family members on either side. I'm not mixed race by any chance, I'm full Asian, but I don't know how my hair isn't like anyone in my family. Odd, I guess?
