Is being keloid prone hereditary?

Yes: Yes, aggressive scar formation is genetic...Although not absolute, the risk is increased.

Can be: Keloids can be hereditary. Keloids can usually be treated, but the earlier you seek treatment the better the out come will be. Seek a plastic surgeon with experience in this area. Topical creams or injections can be beneficial. Ear piercings are a common cause of keloids...If you are prone to keloids, it is best to not pierce your ears. If you must, only use surgical steel or 24k gold posts.

Predictable: The darker one's skin color, the more the tendency toward keloid formation increases. Keloids are more common (but not inevitable) in asians, latinos, dark-skinned indians, and africans. There is definitely also a hereditary component.

Yes: The exact genetics is not known but people who make keloids often have children who make keloids. It is possible to have a parent who is keloid-prone and not be keloid-prone yourself, however.

Yes: Clearly keloids have greater tendency to occur in darker skinned races and to that degree they do have a genetic tendency.
