From everything I've read, the ONLY things that work are:
1) Needle electrolysis (galvanic, thermolysis or blend using needles inserted into the follicle - NOT radio, NOT tweezers).
2) Laser (somewhat controversial, though many swear it's worked great for them - including myself. LightSheer or Coolglide laser + dark hairs + fair skin + 10 or more sessions = good chance of success, IMHO)
There are home galvanic electrolysis kits available. I used one years ago, and it DID work for me. But it'll take you 20 years to do it yourself, and you risk skin damage. It's also very tedious and difficult to do it solo. My wife did it on me (the sadist, lol).
