I was so disappointed. I seem to be growing eyebrows, will wait and see, but the extender was a huge disappointment. It was like using beard shavings with shiny glue. It blobs, you can't get it to go where you want it, it dries shiny and unattractive, no instructions of any kind came with this duo- not what I'm used to from HSN. I was very hopeful. Will continue to use the lipocils until the tube runs dry and see if they come back and stay. Please work on the extender formula.
