I'm really excited about this as I've wanted to do it for a long time. That is, donating hair to make into wigs for cancer patients.
It used to be that they would only take 12 inches but Pantene has a program called "Beautiful Lengths" for people who are willing to donate a minimum of 8 inches. They will even pay for the postage! I found this program through the Canadian Cancer Society website. Hopefully it exists all over.
I've earmarked this spring as my date for the cut. I'm even going to splurge and see my old stylist for a chic new look.
