I have the "pompadour"/combover type hairstyle too and have probably tried 10+ products over the past 2 years as my hair is very stiff and it also grows in a forward direction (that's what my hairstylist says) so it makes it very hard for it to stay slicked back. I use a combination of a wax and surprisingly, Gatsby liquid wax
The Gatsby liquid wax is surprisingly very very good, goes on like a gel but holds like a very strong wax and gives a very slight wet look and shine which I like. It also holds for the entire day and sometimes if I'm rushing to work and don't have time to shower it stays until the end of the next day too lol!
