In March, the Marine Corps ordered Marines diagnosed with pseudofolliculitis barbae, which leads to unwanted bumps and painful ingrown hair from frequent shaving, to undergo medical reevaluation within 90 days to determine whether they still required a waiver.

That administrative message outlined a phased treatment plan for Marines affected by the condition, with the ultimate goal of “returning service members to grooming standards and ensuring maximum warfighting readiness.”

About 60% of Black men are affected by the condition, according to the American Osteopathic College of Dermatology.

A fantastic song as well!
