Everyone has different approaches to styling the french crop, but a nice way to get started is with a decent matte clay (pomade is fine as well, it just won't bring out the texture as much).
Apply a small amount of product evenly throughout your hands, and begin placing it evenly throughout dry hair. Some men prefer to start at the back of their head and work their way forward to ensure that there is even coverage, but it is purely personal preference.
Once the product is in, you can begin to pick and direct the hair in the direction you want it to go.
