advice please


I’m a 21 year old new member, who was just advised to get started on laser early on. I know the procedure(s) can be extremely expensive. I live in nyc and would be interested in doing my back and shoulders (not too much hair yet). I do have fairly light skin and dark hair. Can anyone make any suggestions? I know there are many different kinds of lasers. Is there any kind that works best? Do I see a dermatologist first? Can anyone make any suggestions as to where I would get laser done and how much it would cost? Thanks. I really appreciate any help.
