Personally It bothers me when I see young girls (anything under, say, 13) with ANY kind of fake hair. I know that combing a head full of hair daily can be time consuming to say the least, but I just think it's a great time to bond with your daughter and show her that she can manage/take care of her hair herself.
I have nieces whom I have NEVER seen their real hair. And to this day those girls hair is a hot mess (damaged) and they do not know how to style their natural hair. They know how to weave it up, braid it up, phony-pony it up, but that's it.
Maybe I'm old school, but I just remember how nice it was being between my mom's knees as she combed my hair. Sure, sometimes it hurt like heck because she wasn't using a wide-toothed comb
but it was still kind of our special time. And I couldn't wait until I could start styling my hair myself -- MY hair. I didn't immediately think, "Oh, I'd better go to the BSS and get me some fake hair if I want to look good." I knew that my own hair could be made to look nice if I put the time in to style it.
Anyway, I don't mean to ramble, but I do think that kids learn lessons at early ages, and a lot of young girls are learning from their own parents that their own hair is impossible to groom without "special accoutrements."
