I started using this product in October of 2017 .. I had been a long time wearer of extensions .. when I removed them .. it left my natural lashes patchy short and pathetic. I love makeup and the final step to a gorgeous application of eyeshadow is lashes. I hate glue ons so I started grandelash md .. honesty without high expectations. I’m impatient.. but I did it religiously once a day at night .. within a month there was obvious volume.. the patchiness was filling in by month 3 my lashes were much longer and full. I’m on month 4 .. and my lashes literally look fake .. I love them and this product :) get it you won’t be disappointed and dr.cherry... his is authentic.. don’t be fooled by super cheap fakes.
