This is a wonderful thing you are doing. I lost my father to cancer when I was quite young.
My step daughter is shaving her head to raise money(not sure if she'll go thru with it) but lately her hair has been getting shorter and shorter. She's got the forms and has asked her school if they have any objections which they don't.
SD suffers from depression and is always seeking attention from her peers. I'm hoping she's doing this for the right reasons, because she doesn't know anyone who has cancer. Only heard about my father.
I will be putting my "purse" behind her and supporting her in this but would still like to wish you all the best and hope that your friend can overcome her battle against this horrible disease.
