Or is it like one of those urban myths?
My neice has asked me to help her with a science project for school (biology, chemistry something like that where they're testing the effects of chemicals on the body I think ), and has asked me if I would see if it works.
I'm quite inclinded to help her as I'm in maternity leave and therefore it doesn't matter so much if my hair gets ucky, but I was just wondering if anyone had ever done this and if there was anything I specipically needed to do (or not as the case maybe).
Answers on a postcard! Thanks
