Hello, well I have never heard of graveyard shifts causing cancer, but these days what doesn't give you cancer, right? Anyways, I wanted to let you all know about this amazing cause that I am working with. I lost my father to cancer in 2004, so this is a very important issue to me. I am a community ambassador with Pantene Beautiful Lengths and Million Inch Chain, and together we are trying to gather 1 million inches of hair so that we can make them into wigs to give to women. These women need this because, to lose your hair to this disease can be especially damaging to your self esteemm, and women battling cancer need all the confidence and strength they can get so they can face this head on. I am hoping many of you out there will be compelled to donate to this very amazing cause. If you would like more information on how you can contribute by donating your hair, then please visit this website http://www.beautifullengths.com/en_US/million_inch/million_inch_qa.jsp
