Nail biting may seem like a small bad habit, but for many, it’s a deeply ingrained behavior that affects confidence, hygiene, and appearance. If you’ve tried to stop but always end up back where you started, this guide will help you understand the root causes — and give you a step-by-step plan to break free within 30 days.
Nail biting — or “onychophagia” — is often a subconscious behavior triggered by a mix of psychological, physical, and environmental factors.

Boredom or lack of stimulation
