longhairdon'tcare : Actually, I checked the FDA web site before I posted, and they said *precisely* what I did, albeit in slightly more formal language. A lot of people cite the FDA approval without researching it or understanding what they mean by "reduction."
http://www.fda.gov/radiation-emittingproducts/resourcesforyouradiationemittingproducts/ucm252761.htm"Several manufacturers received FDA permission to claim, "permanent reduction," NOT "permanent removal" for their lasers. This means that although laser treatments with these devices will permanently reduce the total number of body hairs, they will not result in a permanent removal of all hair. The specific claim granted is "intended to effect stable, long-term, or permanent reduction" through selective targeting of melanin in hair follicles. Permanent hair reduction is defined as the long-term, stable reduction in the number of hairs re-growing after a treatment regime, which may include several sessions. The number of hairs regrowing must be stable over time greater than the duration of the complete growth cycle of hair follicles, which varies from four to twelve months according to body location. Permanent hair reduction does not necessarily imply the elimination of all hairs in the treatment area."
Notice that it says that laser WILL PERMANENTLY REDUCE THE TOTAL NUMBER OF HAIRS. It's permanent reduction only because it does not remove *all* hairs but does permanently remove those which are killed, exactly as I said.
Anecdotally, I had laser five years ago with absolutely zero regrowth. Bear in mind that people who are confused about how hair grows can think they're seeing regrowth, too, as dormant hair follicles wake up and produce hairs that were not there to be killed while the treatment was going on; this is why laser recommends several sessions spaced the approximate dormancy period of a hair follicle apart (4-6 weeks).
I also did the math and for what laser cost in my area, I could afford to have it fully redone every 5 years for the next 50 and still not spend 1/10th what electrolysis would cost me, so frankly even if were not permanent (which it has been), I'd be happier to have chosen laser.
