I started LHR 15 months ago with groupon at reputable salon. I purchased multiple packages 2 large and 1 small area since my goal was to never shave again in my entire life. for the amount of $ I spent, I was hoping for no stragglers. I have random places were I will need additional treatment so that is disappointing. However, overall I am pleased.
laser makes a difference - 2/3 of way thru my treatments, salon updated the equipment. I wasted some time with the outdated laser system so be sure to investigate what type of laser, equipment age, and which clients will benefit from that type of equipment.
technician makes a difference - more or less experienced. never rush thru the appointment. since the laser follows the hair follicle, if they tech is pressed for time, they may skip the overlap. the technician will get to see areas not normally shown in public, so if you or the tech is a prude, could be a concern.
hair makes a difference - thicker the hair shaft, the better the results. hair shaft is thinner in some areas, for ex knees and the color is less dark. ideally, salon equipment will adjust for diameter.
salon makes a difference - some of my gf went to a salon that gives cash discounts. several reported they were burned by the laser, and very uncomfortable process. i would recommend you avoid the shady salons.
you make a difference - laser (or at least the one being used at salon) works best with dark hair/light skin. i had NO IDEA i could not tan thru this process. i have a high tolerance for pain so i was generally not uncomfortable during treatment. some areas hurt a little more then others. expect some discomfort especially if your pain tolerance is lower.
some ppl will need additional treatments for maintenance. its not inexpensive.
i am happy with the outcome but will be purchasing a maintenance package, on groupon deal. i only shave once every month to get the few spots that didn't take as well. It has saved me time in the morning and I don't need to worry about razor blades or razor burns or cutting myself.
