👉 Onychognathia is a type of hair growth that occurs on the sole of the foot, typically around the arch of the toe. This condition can be caused by various factors such as genetics, hormonal changes, or environmental factors. It's characterized by a cluster of tiny hairs that form a dense layer at the base of the sole, often covering up to half of the foot. Onychognathia is not considered a disease but rather an inherited condition.
