Onyx Professional Stop the Bite Nail Biting Prevention Polish, 0.5 fl oz — Clear Bitter-Taste Deterrent, Daily

Onyx Professional Stop the Bite is a bitter-tasting nail polish designed to deter nail biting and thumb sucking so nails can grow back healthier.

This clear, easy-to-apply formula delivers an intense unpleasant taste on the nails that discourages chewing immediately upon contact. Made in the USA and packaged in a 0.5 fl oz bottle, it can be used as a top coat, base coat, or preventive layer over natural nails. The product targets habitual nail biters and thumb suckers without coloring the nail, making it discreet for adults and teens.

How quickly will I notice a reduction in nail biting?

Most users report an immediate behavioral response because the polish tastes bitter right away. While some people stop biting on first use, habit change for others can take a few weeks as new nail length and routines develop.

• Immediate bitter taste on contact
• Visible nail regrowth typically within 2–4 weeks
• Consistent reapplication supports long-term habit change

How do I apply and maintain the Stop the Bite polish?

Apply to clean, dry nails as you would a regular clear polish: one or two thin coats is usually enough. Reapply after washing hands or when the shine fades; use the included nail file to shape any regrowth and maintain neat edges to reduce temptation.

• Use as a base coat, top coat, or standalone clear coat
• Reapply when polish wears or after handwashing
• File nails gently as they grow to discourage picking

Is this safe to use and suitable for daily wear?

The formula is intended for topical use on nails and is manufactured in the USA to cosmetic standards. It’s designed for everyday wear and fits into regular nail care routines without adding color, so it remains inconspicuous on natural nails.

• Clear, non-coloring finish
• Can be layered under or over standard nail polishes
• Designed for routine, daily application

What results can I expect after stopping nail biting?

When biting decreases, nails have a chance to grow longer, smoother, and stronger. Over time you’ll see reduced hangnails and a healthier nail bed appearance as chew-related damage heals.

• Improved nail length and smoother edges
• Fewer jagged tips and less splitting
• Cleaner-looking nails and reduced need for frequent manicures

Who this is for: Onyx Professional Stop the Bite suits adults and teens trying to quit nail biting or thumb sucking without dramatic cosmetic changes. It’s ideal for people who want a discreet, over-the-counter behavioral aid that fits into familiar nail care habits. If you prefer a clear finish, want to continue wearing colored polish, or need a non-staining deterrent for habit control, this product provides a simple, immediate option to help nails recover and grow.
