Ruling on removing body hair

What is the ruling on a woman removing hair from her body? If it is permitted, then who is allowed to do that for her?

Praise be to Allah, and blessings and peace be upon the Messenger of Allah:

It is permissible for her to do that apart from the hair of the eyebrows and head; she is not permitted to remove that hair or any part of it. She may do that herself or her husband or one of her mahrams may do it with regard to the parts of the body that they are allowed to see; or another woman may do it with regard to the parts of the body that she is allowed to see.
