Uhm, if waxing didn't work, either the hair was too short, either you were doing it very wrong, either a combination of those.
And there was a "sensitive" head. Some sort of massage rollers that are supposed to trick skin into not feeling the pain. They only got in the way, so I didn't use them.
Since I've had an awful experience with an epilator, I'm really doubtful about spending on one again. I mean, not only did it hurt like heck (like, worse than laser ever did), but it just wasn't strong enough to pull hairs in one go, a lot of the time. It pulled on them a few times before FINALLY getting them. And that hurt. Also, on my upper thighs and behind my knees, the hairs were just so attached to the skin and the skin was so flask I could never get them. Only incredible pain, pulled hairs and sometimes pinched skin.
Sigh, maybe I should start saving up for a super massive treatment at E3000. Oh wait, the cost is almost my yearly income. Heck, right now I can't even shave the most annoying areas (thighs and whole underwear area), because they get full of painful pimples if I do. Of course, they get full of smelly, disgusting pimples, ingrowns and whiteheads if I DON'T, on the other hand. 2 cm long butt hair ? Hell yeah!
...I hate my body. It's just wrongly manufactured.
