What Is Acne Keloidalis?

A keloid is a type of scar, that continues to grow and often itch, well after the underlying wound has healed.

Acne keloidalis is a type of scarring reaction most often seen on the nape of the neck or scalp.  Acne keloidalis may develop after a ‘close shave’ where the hairs have a chance to ingrow and cause inflammation and then scar.
