Playboy's Twins Hair is not suitable for donation

Hugh Hefner's twin girlfriends may seem perfect, but their bleached blonde hair was recently deemed "too overprocessed" to be donated for charity.

The revelation about the poor-quality locks of Karissa and Kristina Shannon comes after 2008’s "Playmate of the Year" Jayde Nicole established her own charity "Lengths for Love," and encouraged other playmates to donate their hair toward raising cancer awareness. Nicole has enlisted the help of dozens of playmates and bunnies from all eras to "hop" into the project too. Just one major problem — hair that has been bleached can’t be used to make wigs and well, that pretty much cuts out 95 percent of the Playboy population — including the twins.
