From someone that has had laser done: I went three or six day/treatments of approx 8 hrs each (enough time to cover the entire body) three times. Been hair free for about six years. The key is, the type of laser. Mine was type "C". Be repaired for the worst, most intense pain of your life. The laser burns the hairs down to the root in 1/4 inch square sections. That's a lot of squares. I still have to go for a follow up on the face. I think the price was $3000 or $1500 or more. Been too long, but money well spent.
