I was sent a tube of Covergirl’s Last Blast Fusion to review. It comes it 4 shades- very black, black, black-brown, and brown. I was sent black-brown. I think it was the right choice for me- I have very dark brown hair, but not quite black. My eyelashes are not very thick, but they are when I use lash blast! It does not irritate my eyes, goes on smoothly, and gives me thick, full lashes. I want to try it with an eyelash curler. Maybe I can get thick, full, curly lashes! (A girl can dream!) Lash blast fusion was easy to use and didn’t clump, as well. I did need to put on several strokes to get that “thick” look, but it was worth it. Thanks Covergirl!
