Query: Head Slick is great. Packaging is not.

I love Head Slick for all the reasons already listed. What I don't like is the bottle and cap. The product tends to glue the bottle cap shut. I've had to remove the cap and clear the coagulated product in the neck and cap. Finally, I found another bottle cap that fit, and threw the original away. 5 stars for the product, -1 for the cap.***** I found a pump dispenser bottle with same size cap and thread, put it on the Headslick, and it works great. No waste, no mess, no clog, I get exactly as much as I want. This is how it should be packaged.
