I tried Fluridil once too but it was way too complicated to apply trying to pour it from a broken glass ampule onto your head. In addition, I only had a small area to apply it to so using one entire ampule every day would mean I'd literally be wasting 75% of it, if not more. Also, it was like trying to apply water to your scalp, you put it on and it instantly starts running all over the place - not good for temple application. After two days of trying to figure out how to apply it I gave up and sold the remaining 88 ampules on Ebay. At least with this Flutagel it's VERY easy to apply, it's like like rubbing clear Elmer's Glue on your scalp. If you want it there you put it there and it stays.
