Oh head lice... Growing up the oldest of five kids we all got lice at least once a year. I would get mine washed first so I could help Mom wash and brush the rest of the kids' heads. Ug... lol wonderful memories!
I'm hoping my child is like me when it comes to personal hygiene. I can't stand for my hair or face to feel greasy (I shower twice a day) and I can't sleep unless I've brushed my teeth and bathed at night. I found some cute jawline bobs and reverse bobs online that we'll probably go with until she is old enough to decide on her own what she wants to do with her hair.
As for color... if it weren't for my job I'd have crazy colored/styled hair and I'm almost thirty LOL so that won't be an issue for me! If she wants hot pink hair, that's fine. Let her do it while she's young and able to without repercussions from work and the real world. You're only a kid for a little while.
