A fine, smooth probe slides alongside the hair and into the follicle. A controlled current is delivered to the base, disabling the growth cells that produce the hair. The hair is then lifted out with tweezers — no pulling.
That is the entire mechanism, repeated one follicle at a time. It is the only method recognized by the FDA and Health Canada as permanent hair removal. Not "permanent reduction." Permanent removal.
The trade-off is time. Electrolysis is slower than laser by design — but the result does not need to be revisited.
