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.”

“Hollywoodland” is an exploration of fame and identity.
