ok, after being in the laser section i changed to electrolysis becasue i think is better for the areas i want to treat (front and back neck, shoulders and back) so, with electrolysis you get a hair killed in one session or its just like laser, it gets thinner with every session, i mean, do i have to use electrolysis more than one to kill one hair, so if i want to remove the hair in my back(altough its not fully covered with hair and its one of the last areas of my body that its starting to develop hair)i have to spend more than once to treat one specific area?


For most individual hairs, they are killed the first time, but you will have to have more than one treatment in each area. Read on:
