Review (3/5): It may work?
I'm a lash-addict! I have all the really nice mascaras (Chanel, Bobbi Brown, Dior) and for a year I got regular eye-lash extensions twice a month. I really wanted to like this but I can't. I put it on morning and night for five days straight, and I always woke up (and spent the day) with itchy eyes. I tried to convince myself that it was something in the air, but when I forgot to use it I was just fine. So I stopped using it and I was just fine.
However, I do believe in the concept. My family in Jamaica swear by putting coconut (or castor) oil on the lashes daily to keep them supple. When they're moisturized they don't fall off as fast, and putting on mascaras certainly aid in drying out the lashes. I try the oil-on-the-lashes thing but I've made the decision to stop using this product.
