I use HeadSlick, I have tried the oil by King of Shaves, I didnt like the oily residue, but it gave me a really close shave
I agree with medicineman. I use a shaving soap and a brush. There's nothing like the feeling of putting warm brush on your head and face. Also the brush helps lift up the hairs as well as exfoliate the skin.
Been unable to find Headslick here in Australia. I use several types of creams and gels but my fav is King of Shaves senstive gel.It foams a little bit but still allows you to see what you are doing.I am partial to the old school Gillete Lime scented foam.
