Asking for a friend who's very concerned that her 1 month old daughter is quite hairy. Are there any home remedies you could use to reduce hair growth on the face, arms and legs?

I agree with Hui Qun Ng. It could be just lanugo and it will shed away eventually. So there is no cause for alarm. Also some babies and children have more body hair than others and it will just grow out once they are a bit older. I would not try to do anything about it. And also, I don't think there is anything wrong with it actually. They look cute that way :-) Anyway, I would not try any home remedies as this would cause more damage than good. Hope this helps :-)
