Thicker, not longer, maybe more time is needed
I'm using this to fix my eyelashes after I did false lashes for my wedding, it's working great my lashes are growing back quickly and they seem thicker then they were although they don't seem to much longer, but they are blond at the ends so hard to tell really. Definitely thicker though.  I've only been using it for about a month.
