Unwanted hair on a young girls back?

You say she was born hair free and the hair growth on her back has become heavy and apparent in the past few months...

To me it seems absolutely crazy that you're asking for suggestions on the best form of hair removal. Firstly she is a very young CHILD do NOT touch the hair on her body. Most 5 year olds wouldn't notice a hairy back anyway! And you do know you can get swimming costumes that cover the back?

Get her to a doctor and explain the sudden hair growth. Hopefully there will be an explanation for it and you and your friend will not need to dream up the best ways to remove hair from a childs body.

Absolutely bloomin' crazy!
