I wouldn't just arbitrarily start splashing with witch hazel after shaving. I heard this a lot and started doing it a few months back and seemed ok at first, but then I started noticing how dry my skin and hair was getting. I mean my whiskers were turning into steel wool. No amount of prep and no cream or soap I tried would give me a comfortable shave. Everything felt REALLY harsh. Do you have acne or ingrown hairs? If it's acne then I'd say you may want to use a facial cleanser before shaving to help lift oil and dirt from your pores. I wouldn't use anything with salicylic acid for the same reason as above unless you don't have issues with getting dried out at all. If you're getting ingrown hairs try changing you technique up a bit and, or some different razor/blade combos to help better cut the hairs so they don't curl back under your skin. If you use witch hazel then I would dab it with a cotton pad or something on the affected spots and then follow with a light moisturizer. Just thoughts...do what works best for you brother.
