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

Onyx Professional Stop the Bite is a bitter-tasting nail polish designed to deter nail biting and thumb sucking, applied like a regular clear top or base coat to discourage the habit while nails grow back.

If you or a loved one are trying to break a nail-biting or thumb-sucking habit, this product provides a simple, topical deterrent that works immediately. Made in the USA and packaged in a convenient 0.5 fl oz bottle, the clear formula can be used alone or layered over colored polish. It’s intended as a behavioral aid — by creating an unpleasant taste when nails are brought to the mouth, it reduces the reinforcement that sustains the habit and encourages healthier nail regrowth.

How quickly will I see a change in nail-biting behavior?

Many users notice an immediate reduction in biting because the bitter taste removes the reward that keeps the habit going. Consistency matters: apply daily until the behavior lessens and nails begin to heal.

• Works on first application for many users because of the strong bitter taste.
• Reapply after handwashing, showering, or when polish shows wear.
• Combine with nail filing to shape new growth and reduce temptation.

Can I use Stop the Bite over colored polish or as a base coat?

Yes — the clear, versatile formula serves as either a base coat under colored polish or a protective top coat over nail color. It leaves no visible tint so it fits into any manicure routine without changing the look.

• Use under color to add a bitter barrier beneath cosmetic polish.
• Apply on top of polish to maintain the deterrent between manicures.
• Works equally well on natural nails and artificial tips.

Is this product safe and easy to use for adults and children?

Formulated for topical use on nails, it's intended to be a non-invasive behavior aid. Parents should supervise application for younger children and consult pediatric guidance when needed. Avoid contact with eyes and broken skin.

• Apply a thin coat to clean, dry nails; allow to fully dry before contact.
• Keep out of reach of small children when not in use due to bitter taste.
• Safe for daily use as part of a nail care routine when directions are followed.

How does Stop the Bite support faster nail recovery?

By discouraging biting, the polish reduces repeated trauma to the nail plate and surrounding skin, allowing natural growth to resume. Pairing the polish with simple nail care speeds visible improvement.

• Bitter taste reduces finger-to-mouth contact that damages nails.
• Use the included or recommended file to shape regrowing nails smoothly.
• Regular application encourages a consistent barrier while nails heal.

Who is this for: Onyx Professional Stop the Bite is for anyone looking for a low-effort, topical aid to reduce nail biting or thumb sucking — adults, teens, and older children under supervision. It's a practical option for those who prefer a non-prescription approach that integrates seamlessly with manicure habits, whether used as a clear base, a top coat, or a standalone deterrent. If you want a simple behavioral tool to help your nails recover and discourage the mouth-focused reinforcement of the habit, this product offers an immediate, easy-to-use solution. For persistent behavioral concerns or skin reactions, consult a healthcare professional.
