If you are getting a HeadBlade, you can get the HeadSlick. You can get the Matte Head Lube as well, if you don't like shiny.
That's how I started...now I pretty much go with the HeadSlick and when I'm done get awesome results with Tolsum aftershave splash...
It really depends on your hair after that, mine is so thin I can get away with shaving it every 2-3 days and my blades go a long way...but if you want to keep it smooth all the time, shaving it every day is the way!!!
