Biting your nails is a difficult habit to break, for both children and adults.
Often automatic, this action occurs during moments of stress, boredom, or concentration. Over time, nails become short, weakened, and uneven. To stop, several solutions can be combined: identify when the action occurs, care for your nails, and use a suitable treatment such as Sensitive Repair Bitter Nail Polish to create a real barrier against nail biting.

Why do we bite our nails?
The science behind it
Biting your nails has a name: onychophagia. It is a common behavior that gradually becomes automatic: many people bring their fingers to their mouth without even realizing it.
Fingernails grow by around 3 mm per month, so it takes several months to regain their full length after stopping.
The action often occurs in situations involving stress, concentration, or boredom. It can also be triggered by a small irregularity: a broken nail, a rough edge, or a small piece of skin sticking out can make you want to “correct” the area with your teeth. The problem is that this action reinforces the reflex and further weakens the nail.
How to stop biting your nails: the 3-step method
1. Identify when you bite your nails
Identify the situations when you most often bring your fingers to your mouth: in front of a screen, at work, on public transport, or during a stressful moment. This awareness helps you anticipate the urge and interrupt the action before it starts.
2. Keep your nails short and carefully filed
A rough edge can easily trigger the urge to bite. Gently smooth the edges with a soft file, such as the Glass Nail File, ideal for fragile nails, and trim them neatly if needed with a nail clipper. The aim is not to shorten them further, but to keep the edges even.
3. Use bitter nail polish to help stop nail biting
For bitten nails, bitter nail polish is a valuable aid: its very bitter taste acts as a signal when your fingers reach your mouth and helps you become aware of the action.

How can you repair your nails after biting them?

Good habits to stop biting your nails
- Keep your nails well-groomed: even edges reduce the urge to nibble them.

Helping children stop biting their nails
For children, it is better to avoid making them feel guilty or systematically reprimanding them: the goal is to help them become aware of the behavior and support them gradually. Sensitive Repair Bitter Polish, suitable from age 4, makes the behavior immediately noticeable. Combine it with a comprehensive approach: identify when the child bites their nails, encourage their progress and care for their nails regularly.
A healthcare professional's advice
If nail biting is very frequent, causes injuries, redness or an infection around the nail, or is linked to significant anxiety, speak to your pharmacist or doctor.
