Permanent hair coloring is a bad idea for children. It can damage their scalps and increase risks for cancer. Temporary hair dyes however are okay for children over the age of 8. No hair color services however have specific hair coloring for children.
It means she is changing her hair colour!
Yes, she has dyed her hair a different color before.
Harry and Ginny's children al look different than each other. Lily is the spittting image of Ginny with red hair and brown eyes. James looks very much like Harry but has Ginny's brown eyes. Albus is the only one of Harry's children to have Harry's (and his mother's, Lily's) bright green eyes.
ANSWER:Pardon the pun, its in your genes (jeans). Your biological parents have passed on traits to you that they received from their ancestors and this will have an effect on your hair color. You can have brown privates and blond hair, or brown hair and a red beard. The color of the hair on your arms can also have a different color as well.
Hair color genetics are complicated. Your child could actually have any color hair, from blond (less likely) to brown or black (more likely).
Sometimes. Children look like a mix of their parents and their parents' genes. So a girl can have the same height as her father but the hair color of her mother.
