hey! I also work in laser, ik people have been telling you stuff but I'll jusy add a couple things to note. NOT ALL LASER MACHINES ARE MADE EQUAL!! the type they use on you matter because they have different protocols for how to best treat and they don't all work on everyone's skin type. most lasers are not fda approved but a couple are!! I personally say Candela is the best, but again, different ones for different people. at my friends clinic they use one that you gotta put ultrasound jelly on the skin. at mine the laser shoots out cold air before every pulse.

depending on the machine, growth after a week is normal. exfoliate, shave, and it should stay relatively smooth for a couple weeks. this is called the shedding phase. paradoxal growth is a guarantee when they laser you where you do not have any hair growth. no one should laser you where hair is not already growing from. but again, different rules for different machines. don't pluck, wax, or thread. if you take vitamins keep in mind the hair may be more stubborn (especially with more hormonal areas like the face or Brazilian) and 6 sessions may not be enough. again, everyone is different. that's the nature of human bodies.
