Did you read this part in the FAQs? I clearly understand your question and James’s answer is somewhat incorrect and misleading. It’s absolutely permanent on the right type of hair with the right settings and machine.
The simple answer is - whatever hair is affected by laser is gone for good. The heat applied disables the follicle from producing any new hair. “Reduction” simply means that not 100% of the hair on an area will be removed – and that is due to the fact that laser can only affect COARSE hair. You’ll get to a point after the usual 6-8 treatments needed where only sparse fine hair will remain. Thus, this is called a “reduction” and not 100% removal.
If your last question is directed to me, the answer is YES. Thus the first link below. It’s been over 2 years on most areas I have treated and I still don’t have any hair (or expect to).
P.S. Pasting the answer from the FAQs (you should read ALL of them at the link below):
- Is laser hair removal permanent? Are there other permanent hair removal methods?
Hair removal lasers have been in use since 1997 and the Food and Drug Administration approved it for “permanent reduction.” They permanently disable hair follicles, however you have to remember that laser hair removal doesn’t work in the same way on everyone and doesn’t remove 100% of the hair in an area. Generally, this means that you shouldn’t expect to remove every single hair from an area, although you can remove the majority of it. Most people need to follow up with electrolysis treatments for any remaining hairs to achieve complete clearance, if desired, as the remaining hairs become too sparse and fine for laser to target. Some will also need touch-up treatments about once a year, especially on large areas, after the initial set of 6-8 treatments for any new growth your body may develop with age on certain areas. It has also been observed that some people seem to be non-responders – this is not confirmed and reasons are not known, and may in fact be due to lack of skill on the part of many laser operators and/or the type of machine and settings they are using. Keep in mind that it’s hard to judge whether someone’s lack of results is due to a potential underlying medical condition that causes continuous growth and makes it seem like laser isn’t working, if the treatment wasn’t performed properly, or whether for some people it just doesn’t work for currently unknown reasons. In essence, you can’t determine what your personal results with be like unless you try it. Results depend on many variables involved, including the tech’s experience, type of laser used, how settings are set, etc. It is recommended to start with one smaller area and see you’re your hair reacts before committing to an expensive set of treatments on many areas at once.
Electrolysis is an alternative permanent hair removal method that has been used for over 125 years. It involves treating one hair at a time and is a good option for smaller areas (like eyebrows or upper lip) where precision is necessary. It does take considerably more treatments compared to laser to complete a large area, but is an option as well. At this time, it is as the only permanent option for very fine and light-colored hair.
