What is the cause of finger hangings?

Finger barbs are considered to be reverse stripping, clinically called barbs, which are caused by cracking of the proximal or lateral edges of nail folds and showing small pieces of long triangular epidermis, accompanied by pain. It is mainly caused by occupational injuries or neurotic habits such as nail biting. It may also be caused by dry skin and cracks in the stratum corneum of fingers. If it does not heal for a long time, it may be a manifestation of vitamin C deficiency. The nail epithelium is connected downwards or backwards. When torn off in a hurry, it will further tear the barbs, causing more obvious pain, damaging the surrounding skin, and even causing hand infection. It is a very good solution to cut off the roots with scissors. After cutting off, pay attention to local hygiene.
