Curved hair plus a close shave is how jaws collect bumps. Leave a millimetre, drop the alcohol splash, put SPF on the mark.

Key takeaways

PFB is hair re-entering skin, not a hygiene sermon.
A guard millimetre prevents more bumps than a new oil.
Alcohol aftershave stings; it does not treat the follicle.
SPF on the jaw stops PIH from locking the map under SA sun.
