Funnily, for permanent hair removal, you actually insert a thin probe/antenna/needle into the tissue, then transmit three times each for 1 second at 13.7MHz at ~180W to destroy the surrounding tissue.
Cosmeticians sometimes also use this to destroy certain blemishes.
- na85 5y agoWow. Do they do that in every follicle?
- kuschku 5y agoYes, it takes a few seconds per follicle, and you’ve got to do it three or four times over half a year on each follicle. It’s obviously expensive and takes quite a while. For most people, IPL or Laser is probably a better option.
- ladyattis 5y agoOnly up to blond hairs which then you have to switch over to electrolysis like me. I have red hair which is really a mix of different hair colors such as light brownish red, 'redder', and blond. Like right now I don't have any beard shadow but I do have many blond hairs left over.
