easy to use [SEP] love the way it comes on i went to get my eyebrows done at my salon and they charge i loved the way it looked but felt was way too much for days thats about how long it lasted so i bought this is it cheaper yes results even better because you can define your brows the way you want but this last only bout max days still not bad if you dont mind saving but having to tint more often they said in the reviews a pill you can split in and get more for your money and i agree so is it worth it yes how long did it last me even being careful to not scrub eyebrows when washing face max easy to do i was nervous at first it is tint but i outlined as if i was using pencil let sit for minutes and yes do one eyebrow at a time it starts to tint fast and one less thing i had to do in the am i just wish it would last longer thats why i only gave it
