|Other names: Agnail|
|The bottom finger has a hangnail.|
It is typically caused by trauma to the fingers, such as from nail biting. Treatment generally involves trimming the hangnail straight, after soaking the hand in warm water and followed by applying a moistriser and antibiotics. Constant application of moisturisers and avoiding repeatedly keeping hands in water may help prevent hangnails. However, they tend to recur.
Hangnails can become infected and cause paronychia, a type of skin infection that occurs around the nails. Treatments for paronychia vary with severity, but may include soaking in hot salty water, the use of oral antibiotic medication, or clinical lancing. Paronychia itself rarely results in further complications but can lead to abscess, permanent changes to the shape of the nail, or the spread of infection. Hangnails will also usually hurt if pulled as it may pull too much skin with it not just the dead skin.
For home treatment, the American Academy of Dermatology recommends washing the hands, clipping the loose piece of skin with a clean nail clipper or nail scissors, and applying over-the-counter antibiotic ointment if the area appears inflamed. Persistent hangnails should be evaluated by a physician.
