YMMV but cold shave works for me.
I used to get patchy shaves and irritation doing the hot shower, hot water shave. Now, good rinse with cold water, lather and shave, alum block and some AS and good to go.
Another trick suggested by a member here is to keep your shaving soap in the fridge, or in a cold spot. Helps load the brush and creates, IMO, a nice sticky lather.
Give it a try...that's half the fun!!
