Just reducing the amount of hairs in my legs...

Maybe this question is there already, however there are so many topics than I do prefer to crate a new topic:

My legs are very hairy so I just want to reduce the amount of hair by having a laser treatment (a couple of sessions tops)and thus having a more cleaner apperance without reaching the 100% smooth look. What I don’t quite get is how that is going to be achieved; I mean the cleaner apperance I am looking for by laser will reduce the amount of individual hairs on my legs or I will keep the same amount but thiner and thiner as the treatment goes?

This will involve getting about 3-4 treatments with someone who is very experienced and thorough (overlaps and doesn’t miss spots to avoid patchiness). The final result will be both: less hairs and remaining hairs finer.
