After nearly a dozen shaves of the sides and neck which are now getting pretty consistent this morning I tried the chin and stash. rough cutting resulting in lots of little nicks that only showed up very slowly after a minute or so. lots of razor burn as well. maybe should stick with the mach blades to finish the chin and stash and use the straight for sides and neck only.
I have been recently shaving cold before the morning shower using proraso preshave and giving it a couple minutes to sink in before lathering up. Seems to work great atleast for the sides and neck. Most of the irritation though happens after the hot shower. wondering if the swelling of the face after such a close cold shave can cause ingrown hairs?
