Query: Needs practice to use correctly; Must exfoliate and really prep skin and hair.

Definitely find a blog where they detail all the steps required to prevent any ingrown hairs. It's painful the first time you do it, and you'll still have baby spiky hairs at the end of it all, but I find it easier than shaving. I like that I can use it dry; I can get comfortable and follow the odd pattern in which my hair grows. I have thick, coarse hair so shaving is very, very uncomfortable (due to the thickness of the hair when it grows back in). When this is used properly it pulls the hair out at the root so the returning growth process is much gentler.
