A product really has to be good for me to leave feedback. That being said, if you have any issue with thinning or sparse lashes you have to try this product. I had a problem with my lashes where all of a sudden one day it looked as though someone had cut a chunk off right in the middle. It was literally a bald spot except for some little stubs. I started using this product but didn't pay that close attention. Well after a couple of weeks I couldn't believe my lashes were actually growing back and the rest were getting thicker. A couple of my co-workers even asked me if I was using new mascara.
You have to try it. The results are amazing!
