The problem

Understanding Onychophagia

Onychophagia, commonly referred to as nail-biting, is a prevalent habit that results in shortened, uneven nails. It is estimated to affect a significant portion of the population across various demographics.

The Nail-Biting Challenge

This habit often leads to aesthetic concerns, including irregular nail length and appearance. Addressing it can improve overall hand presentation and grooming standards.

IMPACTS OF NAIL-BITING

 Nail-biting affects more than just appearance, impacting health, psychology, and daily life as shown in the table above.

Prevalence

This table shows the prevalence of onychophagia across regions, with percentage ranges and estimated millions affected, highlighting its global impact.

The Solution

Nail-Biter Stoppers™ offers a practical and innovative approach to improving nail appearance.

Our precision-crafted covers feature five custom-fit pieces (thumb to pinky) with a safe bitterant coating. Designed for easy application, they provide a discreet physical barrier and a natural-looking finish that helps discourage biting while promoting a polished, well-groomed look.
