My neck is hypersensitive to blade shaving. I've gotten the right side of it under control but I still can't get it smooth and on the left side the area below my sideburn always flares up with irritation and ingrown hairs. This is my routine:
Let the water in the shower hit my face while I wash everything else.
Scrub my face a bit with a loofa
Apply shaving cream and slightly shave my face against the grain (won't dare to try against)
Splash some cold water on my face
Apply astringent on my face
Get sad about 20 mins later when the irritation shows up
Don't shave for a week
I might just have to go with the shadow all the time.
