My mom and older sister both have stick straight hair and I have curly hair. I looked a hot mess until high school when I learned how to do it. I'm still traumatized. I know she is probably too young for product and such but please look into it when she gets older. The interwebz and youtube have a ton of info. For now, don't brush her hair. Just use a wide tooth comb when wet. NEVER brush curly hair when it's dry. No good can come of it.
