Are ingrown toe nails hereditary?

Sometimes familial: The size and shape of toes and toenails are hereditary. If one member of a family has a toenail shape that makes it more likely to be ingrown, then a few other members of the family probably have the same problem. In this way, ingrown toenails can run in the family.

Not really: I do see them in multiple family generations.

Yes: in many cases some patients have a higher chance of getting them based on genetic foot structure. However, most patients get them from their lifestyle and types of shoes they wear. Best wishes!
