The Manucurist Bitter Nail Polish is a transparent treatment polish to help stop nail biting. Its intensely bitter taste helps consciously interrupt the automatic urge to bite. At the same time, the formula cares for stressed nails with dimethyl sulfone, silicon, amino acids, and a plant-based keratin complex - particularly useful when nails have already been weakened or become uneven due to frequent biting.

The bitter nail polish works on a simple principle: as soon as your fingers move toward your mouth, the intense bitter taste makes nail biting immediately unpleasant. This can help you notice the often unconscious habit more quickly and gradually interrupt it.
Unlike many purely bitter polishes, Manucurist combines this effect with targeted nail care. The transparent formula protects the stressed nail surface while also supporting nails that have become thin, soft, or uneven due to frequent biting.
Effects & Care
The bitter nail polish is designed not only as a deterrent polish, but also as care for bitten and weakened nails.
- Denatonium Benzoate provides the intensely bitter taste. Contact with the mouth immediately makes nail biting much less appealing and helps consciously interrupt the habitual movement.
- Dimethyl Sulfone (MSM) supports the strength of the nail plate and complements the formula, particularly for soft or stressed nails.
- Silicon supports the structure and resilience of the nail plate, making it a useful ingredient in strengthening nail care.
- Amino acids from Acetyl Methionine and Acetyl Cysteine support the nail's keratin network and help strengthen its structure.
- Plant-based keratin complex from hydrolyzed chickpea extract, lentil extract, and quinoa oil complements the formula with plant-based proteins and lipids and supports a stronger, more cared-for appearance.
- Apricot kernel oil and biotin complement the strengthening formula with caring ingredients.
The formula consists of 68.5% ingredients of natural origin and dries naturally in the air.
If your nails are also splitting, breaking, or have become very dry due to frequent biting, our guide What really helps with brittle fingernails? offers further tips for suitable care. You can find more products for nails and cuticles in our Nail Polish & Nail Care selection.

How to use
- Apply the bitter nail polish to clean, dry nails.
- One thin coat is sufficient; then allow it to dry completely in the air.
- For a consistently bitter taste, reapply every two days.
- The previous coat does not need to be removed before reapplying.
- The bitter nail polish can be worn alone on natural nails.
- Over colored polish or a complete manicure, always apply it as the final layer so the bitter taste is maintained.
- Do not use as a base coat under colored polish, as additional polish layers may weaken the bitter effect.
- For removal, use Manucurist Nail Polish Remover Green.
- Suitable for those aged 12 and over.
FAQ
How does bitter nail polish help stop nail biting?
The polish contains an intensely bitter-tasting substance. As soon as the nail comes into contact with the mouth, biting becomes unpleasant. This primarily helps you become more aware of the often automatic urge and gradually interrupt the habit.
Is the bitter nail polish visible?
No. It dries transparent and forms only a fine protective film on the nail.
How often should I apply the polish?
Manucurist recommends reapplying the bitter nail polish every two days so that the bitter taste remains sufficiently intense.
Do I need to remove the old coat first?
No. During ongoing use, another thin coat can be applied without removing the previous one.
Can I wear the bitter nail polish over colored nail polish?
Yes. It can be worn over colored polish or top coat. It is important that it always forms the top layer.
Can I use it as a base coat?
That is not recommended. If colored polish is applied over it afterward, the bitter taste may be weakened. For a Green™ manicure, apply the bitter nail polish only at the very end.
At what age is the bitter nail polish suitable?
Manucurist recommends using it from age 12.
What can I do if the taste gets into my mouth?
The very bitter taste is intentional and may remain noticeable for some time. Rinse your mouth thoroughly with water; a mild mouthwash can also be used if needed.
