Well, first of all, find out if your state requires a license for electrologists. For example, the state of California requires 600 hours of schooling, plus a passing score on a written and practical exam before one can be licensed to perform electrolysis hair removal. Consumers can look up the California Department of Consumer Affairs at https://www.breeze.ca.gov and look for the link “Click Here to Access BreEZe Online Services” and then “Verify a License” and “Search by County” or by City followed by “Board of Barbering and Cosmetology” and “Electrologist” to find a licensed electrologist.
For states that do not have licensing requirements for electrologists, there is the American Electrology Association which is a national association that provides electrologist testing & certification. They have a members list that can be found at http://www.electrology.com although keep in mind that the list may not be as complete as the one in your particular state.
Since most offices offer free first time consultation, I would recommend going in person and talking to several different electrologists before choosing someone. Finally, you should see results within weeks to 2-3 months of starting a regular hair removal schedule. I have had clients tell me that they have had electrolysis for months or years on the same small area, and often these clients are surprised at how quickly things disappear after a series of treatments with me. Assuming that these folks were faithfully following their treatment schedules, I can only conclude that different machines and different electrologists work differently, just like different barbers and hair stylists work differently.
