i noticed that my old fusion razor would make my hair growth back uneven. anyone else notice this? i think its the pulling out of the hair follicles that makes them un-uniform.
Even when I shaved with a disposable I used the single blade ones. All the multi blades hurt my face when I shaved.
I never noticed my whiskers growing back uneven with a cartridge, unless my shave was uneven. The same can be said for my DE shaves. Sometimes my chin whiskers grow back faster than my side burns because my chin is more difficult to shave.
I can't say I've noticed this. I shaved with a fusion for a few years (although I'd frequently go 4 days between shaves). I've gone on to a DE and will never look back!
