The short answer to the question is laser hair removal permanent is “yes, maybe” but beyond that you need to understand what is behind the maybe and why it might not be permanent removal of hair from the whole area treated in your case.
All that laser hair treatment clinics may promise is a permanent hair reduction – electrolysis is the only method approved for permanent hair removal. But what does “permanent hair reduction” mean exactly?
It means that a significant proportion of the hair follicles will be destroyed by laser treatment and those hairs will not grow back.
You should experience permanent reduction in hair after a course of laser treatment on your legs
Usually MOST of the hair follicles are killed and you will have minimal regrowth after the recommended number of laser treatment sessions. The remaining hair is easily dealt with by top up treatments (which may destroy more follicles each time) or other hair removal methods.
Just sometimes all of the hair follicles are destroyed and then you have permanent hair removal.
But why do all the hair follicles not get destroyed by laser equipment during treatment?
The laser needs to target the hair follicles when they are at the right stage in the growth cycle in order to destroy them permanently. Hairs are at all different stages in that cycle and although all the hair will be removed during a laser session the follicles may not be destroyed. During any one treatment only a proportion of the hairs will be permanently destroyed.
Also the laser beam has to reach the right depth in the skin for each individual hair follicle. Some follicles may be deeper in the skin and the laser will not reach them with enough power to destroy them. Too powerful a laser would damage the skin so those hairs may not be successfully treated.
Having said all that, most people in recent times with state of the art lasers and multiple sessions designed to hit hair at each stage of growth have successful laser treatment in nearly all cases and enough hair is destroyed to make them happy with the result.
So in summary, if you are asking is laser hair removal permanent you would have to say that you are likely to experience a permanent reduction in hair which will make laser treatment worthwhile and potentially permanent removal.
