Since most LASER training is a 2 to 3 day course, one would almost have to learn more in 14 days. I would advise you to study electrolysis as well, as it would allow you to finish the jobs you start, and provide service to the redheads and blondes who have the least luck with LASER hair removal.
You will also want to find a mentor to help you with the things that only someone actively working the business can provide you with.
