From the totally bald Telly Savalas to the merely thinning Bruce Willis, the Hair Farming Co. can't pay a celebrity to promote its product. Company founder Jacqueline Sabal said she's also approached Frank Sinatra, James Caan, Corbin Bernsen, Julio Iglesias, Jackie Mason and George Carlin without success. "I'm having a heck of time getting these movie stars to admit they're losing their hair," said Sabal, who invented an herbal scalp cleanser called Foli-Kleen 2000, which she claims helps slow hair loss. "Everyone on that list there, I've either spoken to them or to their agents," Sabal said. "They laugh at us."
