Looking for a deep conditioner? At London's Hari's spa, visitors can receive an organic bull sperm treatment fresh from an Aberdeen-Angus bull on a Cheshire farm. Those who have received the hair treatment claim that it "penetrates deeply into each follicle leaving hair supremely moisturized, nourished, shiny, thick, yet light, and vivacious." Called "Viagra for hair," the $138 treatment also includes the protein-rich plant Katera. As salon owner Hari Salem explains, "The semen is refrigerated before use and doesn't smell. It leaves your hair looking wonderfully soft and thick."
