In the United States, keloid scars are seen 15 times more frequently in people of sub-Saharan African descent than in people of European descent. [3]
An injury does not become a scar until the wound has completely healed; this can take many months, or years in the worst pathological cases, such as keloids. To begin to patch the damage, a clot is created; this clot is the beginning process that results in a provisional matrix.
