On Thursday, July 13, actress Diane Lane had seven inches of her gorgeous, honey-colored hair cut live on the Today show to encourage men and women to grow, cut and donate their hair to make wigs for chemotherapy patients.

“If you see somebody suffering… you want to be able to help,” Diane said on Today. “This is how to help — you give your natural resource that only you can give.”

Fifty-eight percent of women say that they fear hair loss more than any other side effect of cancer treatment, according to the vice president of Pantene. The campaign “Pantene Beautiful Lengths” is a venture created by Pantene, the Entertainment Industry Foundation, and HairUWear wig manufacturers.

“It’s so fun and liberating,” Diane shrieked as they cut her hair. “I recommend everybody with long hair go for it once in their life, maybe twice in their life.”
