Hair pomade or anything for the hair used by male preachers that gives them a 'greased down' over-shined hair look. This look basically works against rather than for the over-all minister's appearance.
Most of the Tele Evangelists (Male) who have their hair slicked back uses Preacha Grease, and 'Ghetto' Preachers in the urban neighborhood. "Rev. Toejam's hair is full of Preacha Grease, look how slick and shiny it is..."
