Ladies (and any interested men): I caught an episode of the Doctors on TV, and the female OB/GYN recommended a safe dye for your "betty." The website is bettybeauty.com The available "natural" colors are blonde ("be a true blonde now!":smile, radiant auburn, raven black and brown. They also have fun colors like hot pink, blue and violet. Their website features other products like stencils, styling kits and, hmmmm, here's a Betty for Men, too. Their products are advertised that they are formulated to prevent irritations, are not tested on animals and do not contain ammonia or parabens.
