I've had about 10 on the face, 2 on the lower chest and bikini line and 1 on the arms. I would not recommend doing laser anywhere else besides face pre hrt....hrt will thin out hair elsewhere and make it finer. I have not had any on my legs....I don't shave much in the winter and can go a month and a half and only then will some will be noticeable.....before hrt I could shave and within a week it would all reappear!!
Laser will not get everything....and it is not permanent unless the hairs are in the right cycle of growth. I am on about my 20th hour of electro on my face...I usually have to go 5 days without shaving for her to have anything to work with....and even then their not too noticeable. I could go probably months without shaving but I still feel the little buggers so I shave lightly most days! Its much easier now letting the hairs grow for electro, then it was early on. When first starting I would be so insecure about all the hairs showing...it was much more noticeable!!
