I have always had nice long eyelashes until I bought this product on XMAS EVE, I started using it on top lashes ONLY and used my other brand on bottom lashes because I like the brush better. The VERY next day half the lashes on one eye were gone and now one eye they are completely gone and almost on the other ( my bottom ones are totally fine.). I am 42 years old and never thought I would have to be wearing fake eyelashes! What's interesting to me is that on the website when youn click on ingridents it says not available. Obviously I had some sort of chemical reaction and would like to know what ingriedents caused this. The only reason I chose to buy this brand was because I had a coupon, that's what I get for being cheap!
