The 6 Best Alum Blocks
We spent 21 hours on research, videography, and editing, to review the top choices for this wiki. For any refined gentleman, no shave is complete without the subsequent use of one of these alum blocks. When moistened, these crystal-like sticks or stones are gently rubbed over the shaved area to act as an antiseptic, an astringent, and to combat razor burn. They can also help to stop bleeding from small nicks and cuts. When users buy our independently chosen editorial picks, we may earn commissions to support our work.
