I have a gripe

So I have a small gripe that I need to get off my chest I was at the store the other day and a woman who had a little girl about the same age as Tenley walked by and this little girl had a full head of hair that looked like she had slept on it for about a week and a half. Don't get me wrong I know that kids have a mind of their own and probably that little girl won't let her mom touch her hair with a ten foot pole-but this where my gripe comes in. My little girl that I want so badly to do her hair insists on not growing it!!! At this point I don't think she is going to have hair until her seventh birthday. Is it wrong to put rogaine on kids hair-if so what about the Ronco hair in a can spray---umm that sounds pretty.
