What styling product?
Use common sense. If you have thick, textured hair you can handle a heavier product such as a Clay or Wax. If, like me you have fine, soft hair, lighter products like sprays, mousse or light pomades are better. Experiment.
Always shave after a shower or a bath. Skin is supple and stubble is softer therefore easier to razor. Apply a few drops of shave oil to the face after for a smoother shave.
