i do not shave my face, only my head and neck. i have a few straight razors and i feel comfortable shaving my neck with them, but the idea of shaving my head with a straight blade still isn't very appealing. however, cartridge razors cost an arm and a leg and i am tired of them. i enjoy the process of shaving and was wondering, does anybody shave there head with a de razor? if you shaved with a carthridge before, did you have to make any changes? pre-shave, aftershave, etc. thanks for any info.
