Where in the DR? Your best bet, I would think, is to go to one of the many dermatology/aesthetic clinics in Santo Domingo, but since I have not tried these procedures myself, I doubt I can help with a personal recommendation. I believe that laser hair removal in particular, should be performed by a certified dermatologist, so I doubt you would find this procedure done at "salons". The Jaragua has a nice spa, but I don't know whether they have electrolysis. Hope this helps.
