This question comes up a lot . . . and for good reason, what the heck is the difference between at full set or a half set ?. I always explain it like this: a half set is a good place to start if eyelash extensions make you a little nervous. The application includes about 35 to 40 lashes per eye and the design goes from the outer corners all the way along the lash line to the inner corner closest to the nose. A half set is also a great option for ladies that just want a little "kick" to their lashes. Maybe they wear little to no make-up and mascara only on special occasions. A full set is a whole lotta FABULOUS and is meant for those that want to look like they are wearing crazy fantastic mascara all of the time. So how many lashes is that exactly ? That includes as many ADULT eyelashes as the client has . . . that could be any where from 80 to 120 lashes per eye. That is as many as most people have and it's rare to find someone who has more adult lashes than that. Each ADULT lash receives an extension and the design is created based on the shape of the eye along with a few other factors. In the end, almost all of the lashy ladies that start with a half set end up adding a few more each time they come for a relash. Like anything wonderful . . . you always want MORE !
