Tips to stop biting your nails.

Another option to break this habit is to regularly indulge in professional manicure sessions. The desire usually decreases when you see the result, as well as the money and time spent. However, be careful to choose only accredited salons that properly sterilize their tools to prevent fungal infections. Ideally, you should bring your own tools.

Another method is to cover your fingers, especially if the urge is strong. Gloves, bandages, wraps... these barrier-type interventions can be effective. These devices hinder any contact between the mouth and the nails. They serve both as obstacles to biting, but also as physical reminders not to bite. However, they can be difficult to use consistently or long-term.

Developing coping mechanisms that replace nail biting with a more tolerable alternative, such as occupying your hands with an object to manipulate (squeezing a stress ball, playing with a toy, etc.) or occupying your mind with an activity (playing a musical instrument, painting, knitting, etc.), can also be an effective way to keep your hands away from your mouth.

Note : It is often recommended to chew gum. While the idea may be appealing, it can lead to dental or jaw problems in the long run if you overdo it.

Personal care routines such as regular meals, consistent physical activity, and adequate sleep can help you feel calmer, more confident, and more resilient, aiding in the release of negative emotions. Similarly, to soothe your mind and alleviate the tension created by the urge to bite your nails, we also recommend meditation and yoga.

Thehabit reversal training in combination with a object manipulation training, often also associated with a acceptance and commitment therapy, have proven beneficial in some cases. Indeed, as onychophagy results from a state of anxiety, you can try to remedy it by identifying repetitive, negative thoughts or emotional triggers that make you most prone to biting your nails and replacing them with different behaviors. This can also help to focus on becoming aware of your biting triggers and cravings, identifying replacement behaviors, and cultivating social support.

Medications are not often used for nail-biting. However, in some cases, doctors may prescribe the use of certain types of antidepressants, such as selective serotonin reuptake inhibitors (SSRIs), to help reduce nail-biting. On the other hand, the prescription of SSRIs must be done with care, as this class of medication can exacerbate conditions related to impulses.

Some studies suggest that the administration of N-acetylcysteine, a modulator of glutathione and glutamate, could potentially help reduce nail-biting behavior in the short term, although further research is needed. Indeed, the results are quite mixed in addition to the adverse events reported by patients (headaches, severe aggression, restlessness, and social withdrawal, etc.).

Individuals suffering from chronic nail-biting may require specialized psychological therapy and medication to treat a related psychiatric comorbidity. Indeed, while it does not cause them, onychophagy is associated with a variety of psychiatric disorders, including: attention deficit hyperactivity disorder (ADHD), oppositional defiant disorder, separation anxiety disorder, Tourette's syndrome, major depressive disorder, etc. This suggests that there might be a genetic component.

Note : Not all individuals suffering from these disorders necessarily bite their nails, just as biting your nails does not mean you are suffering from a psychological disorder.
