Hi Robyn,
I shaved for years and started using an epilator and 6 months ago except in my most delicate area and it has made a world of difference.

I am not sure why the chest hair is so different because my chest isn't hairy, I do grow hair in that transition zone between my public area and belly button.

All your hair will become easier to remove, grow back slower and become finer where you use an epilator. If I had back hair I guess I would ask my wife to do it, if you don't have a significant other maybe think about getting your back waxed .
