I know this particular column is from years ago but if there is anyone wanting to dye their pubic hair there is now a product called Betty (www.bettybeauty.com) tag line "for the hair down there!".
There is Blond Betty, Auburn Betty, Brown Betty, etc. for people wanting the carpet to match the drapes or to cover up gray (remember Samantha's failed Bozo the clown bush on Sex and the City?) and also Sexy Betty (bright purple), Fun Betty (shocking pink), and Bridal Betty (blue). The kits are under $20 and have enough product for 3 or more applications depending upon how much hair one has. Plus, they come with cool little pube trimming stencils - lightning bolt, bow tie, peace sign, etc.
It's a great way to have an unexpected, fun surprise!
