I used this product faithfully for a couple months and my eyelashes never looked better in my whole entire life. I tried the eyelash extensions but was sensitive to the glues, so I decided to try to grow my own. Used this product and OMG my eyelashes were so long I had to trim the tips of some of them, I am not kidding!! you could actually see the growth difference. I ran out of this product and tried the Roden and fields brand and No bueno. I could not tell a difference at all, in the length or thickness. So here I am, I have tracked down my old brand and whalala people are asking me if I have extensions again. NOPE they're my own!!! It makes putting on Mascara seriously FUN!! Cant say enough.
