Nothing wrong with being beautiful from head to toe and a few spots in between.
Yes you can dye your pubic hair safely.
I have done it before. I have always groomed my self down below and keep it looking clean and nice & neat. Begin born a natural blonde my hair other place then my head started to change darker as I grew older, I preferred the look of the blonde myself. So one day while dying my hair I put some on my pubic hair during the last 10 minutes of the hair color on my head, it came out beautiful.
You want to absolutely make sure not to ever get any dye on any tender skin inside your labia or this could be dangerous and painful. It's easy to do it just requires a little prep before beginning. Always use Vaseline on the inside of your lips before you begin, this will protect your tender skin and keep the color off. Make sure your have a towel ready and water nearby to rinse.
Leave color on about half the time required for the hair on your head.there is less hair there so it's not needed to be on so long. Also don't over do it, you don't need to have a huge amount placed on this hair, besides you don't want it dripping.
One way I have done it was to climb into a bath already run half way, and just lay there and put it on why your in the tub, allowing it to process without getting any water on it.
