Folliculitis decalvanshttps://en.wikipedia.org/wiki/Folliculitis_decalvans
Folliculitis decalvans is an inflammation of the hair follicle that leads to induration of involved parts of the scalp along with pustules, erosions, crusts, ulcers, and scale.   It leaves scarring, sores, and, due to the inflammation, hair loss in its wake. There is no certainty about the cause of this disorder, but the bacterial species Staphylococcus aureus has a central role.
