Question 1

How do I stop biting my nails with MAVALA Stop?

Accepted Answer

Apply Mavala Stop like a clear polish on clean, dry nails and reapply every two days. Its bitter taste discourages biting each time fingers reach the mouth.

Question 2

Does Mavala ship to Quebec, and is the polish safe for kids?

Accepted Answer

Yes, we ship across Canada including Quebec, free on orders $74.99 and above. Mavala Stop is suitable for children and adults; the bitter agent is unpleasant but harmless.

Question 3

Is customer support available in French?

Accepted Answer

Yes. You can reach our team in French by email for any question about your order or our products.

Question 4

What is the best nail biting deterrent?

Accepted Answer

MAVALA Stop is widely regarded as the best nail biting deterrent available. It is a clear, bitter-tasting nail polish formulated with Denatonium Benzoate (Bitrex) — the most intensely bitter substance in the world — which creates an immediate, unpleasant taste every time nails reach the mouth.

Question 5

How does a nail biting deterrent work?

Accepted Answer

A nail biting deterrent works by making the taste or sensation of biting nails deeply unpleasant, breaking the habit through negative reinforcement. MAVALA Stop uses Denatonium Benzoate (Bitrex) — an intensely bitter compound — which activates on contact with the tongue and mouth.

Question 6

How do I use MAVALA Stop nail biting deterrent?

Accepted Answer

Apply MAVALA Stop like a regular clear top coat to clean, bare nails. Reapply every two days, removing the previous layer with nail polish remover before each application. This keeps the bitter Bitrex taste active.

Question 7

Does nail biting deterrent work for adults?

Accepted Answer

Yes. MAVALA Stop is effective for adults, teenagers, and children aged 3 and older. The Bitrex formula works regardless of age.

Question 8

Is Mavala Stop safe for children and toddlers?

Accepted Answer

Mavala Stop is dermatologically tested and safe for children aged 3 and older. It is free from formaldehyde, phthalates, parabens, SLS, and fragrance.

Question 9

How long does it take Mavala Stop to stop nail biting?

Accepted Answer

Many users notice a significant reduction in nail biting within the first week. MAVALA recommends a 33-day course — a fresh coat every two days, roughly sixteen applications — because that is how long an automatic habit generally takes to break. Stopping early is the most common reason it does not stick.

Question 10

Does MAVALA Stop thumb sucking as well as nail biting?

Accepted Answer

Yes. Mavala Stop is effective for discouraging thumb sucking in children over 3 years old. Apply to the nails on the hand the child typically sucks.

Question 11

What is the best nail biting deterrent for kids?

Accepted Answer

MAVALA Stop is a nail biting deterrent for kids aged 3 and over. It goes on like a clear polish, so a child can wear it to school without it being visible, and its bitter Bitrex taste interrupts the habit each time fingers reach the mouth. It is dermatologically tested, vegan, and free from formaldehyde, phthalates, parabens, SLS and fragrance. It is not recommended below age 3, because taste buds are not fully developed and a very young child can get used to the bitter taste.

Question 12

Is there a nail biting deterrent for adults that actually works?

Accepted Answer

Yes. MAVALA Stop is used as a nail biting deterrent by adults as often as by children — the Denatonium Benzoate (Bitrex) formula does not depend on age. Adults can apply it over coloured nail polish, so it fits into a normal manicure. Reapply every two days, removing the previous coat first, and follow the 33-day plan to give the habit time to break.

Question 13

Is Mavala Stop a bitter nail polish for nail biting, or a medication?

Accepted Answer

It is a bitter nail polish for nail biting, not a medication. MAVALA Stop is a cosmetic clear lacquer whose active ingredient, Denatonium Benzoate, is a taste deterrent. It is harmless if tasted or swallowed in the small amounts involved; it simply tastes intensely unpleasant. You may see it described as an anti bite nail polish or a no bite nail polish — these all refer to the same category of product.

Question 14

Can I use a nail polish to stop thumb sucking or finger sucking in my child?

Accepted Answer

Yes — that is one of the main uses of MAVALA Stop. For thumb sucking prevention in kids, paint it on the nails of the thumb or fingers the child actually sucks, not necessarily every nail. The bitter taste is what breaks the association. It works the same way for finger sucking. Suitable from age 3 and up; reapply every two days until the habit stops.

Question 15

Will Mavala Stop stop thumb sucking for a toddler?

Accepted Answer

Only from age 3 upward. MAVALA does not recommend Mavala Stop for children under 3, because their taste buds are still developing and a very young toddler may simply adapt to the bitter taste rather than stop. From 3 years old it is suitable and widely used for exactly this.

Question 16

Can I wear nail polish over Mavala Stop?

Accepted Answer

Yes. Mavala Stop can be worn on bare nails or over your nail polish — it is clear, so it does not change the colour. Applying it as the final layer over polish keeps the bitter taste on the surface where it is needed.

Question 17

What is onychophagia, and is Mavala Stop an onychophagia treatment?

Accepted Answer

Onychophagia is the clinical term for chronic, compulsive nail biting. Mavala Stop is used as an onychophagia treatment: it is a bitter-tasting clear polish, not a medication, and it works by interrupting the reflex — the taste registers before you are consciously aware your hand is at your mouth. That interruption is what breaks the habit loop. MAVALA describes it as a 33-day course, roughly sixteen applications, reapplying every two days.

Question 18

Is Mavala Stop an invisible nail biting polish, and does it have fumes?

Accepted Answer

Yes on both counts. Mavala Stop dries clear and is not glossy, so it reads as a bare nail rather than as a treatment — which matters to adults who do not want a visible product on their hands at work. It has no strong odour or fumes on application, and it can be worn under or over coloured nail polish.

Question 19

What can I do about the damage years of nail biting have left?

Accepted Answer

Stop the biting first — no repair treatment can outpace ongoing damage. Once the habit is interrupted, the nail rebuilds from the matrix, which takes about six months for a full fingernail. MAVALA Scientifique K+ hardens the new nail as it grows out, Nailactan nourishes the nail root and cuticle overnight, and Mavaderma is massaged into the skin below the half-moon to support circulation at the root. Bitten cuticles benefit from MAVALA Cuticle Cream daily.

Question 20

How often do you have to apply Mavala Stop, and how long does one coat last?

Accepted Answer

One coat of Mavala Stop stays bitter for about two days of normal wear, so it is reapplied every second day — not daily. Before each new coat, take the previous one off with a nail polish remover; layers build up unevenly and the bitterness fades underneath them. Applying more often does not make it work faster.

Question 21

From what age can children use Mavala Stop? Can I use it on a 1 or 2 year old?

Accepted Answer

Mavala Stop is suitable from age 3. It should not be used on children under 3 — at that age taste buds are not fully developed and a toddler can simply get used to the bitter taste, which means the product stops working rather than being unsafe. For a 1 or 2 year old, speak to a pharmacist or your child’s doctor about other approaches instead. From age 3 upwards the method is the same as for adults: one coat every two days, removing the previous coat first.

Question 22

Is Mavala Stop safe? What happens if my child licks or swallows some?

Accepted Answer

Mavala Stop is dermatologically tested and its bitter taste is described by MAVALA as unpleasant but harmless. The bitterness is the safeguard: the taste registers the moment a finger reaches the mouth, which is what makes swallowing any real quantity unlikely. It is meant to be tasted, not eaten. If a child does swallow more than a lick, or if you see any reaction, contact your local poison control centre or your doctor — as you would with any cosmetic product. It is free from formaldehyde, phthalates, sodium laureth sulfate, parabens and fragrance.

Question 23

What are the ingredients in Mavala Stop?

Accepted Answer

The active ingredient is denatonium benzoate — a bittering agent, sold under the name Bitrex, that releases an intensely bitter taste on contact with saliva. It is carried in a clear film-forming lacquer base, which is why the product looks and applies like a clear nail enamel. Mavala Stop is free from formaldehyde, phthalates, sodium laureth sulfate, parabens and fragrance. Denatonium benzoate is the same bittering agent widely used to make household products unpalatable, which is why it works at very low concentrations.

Question 24

How do you remove Mavala Stop?

Accepted Answer

Mavala Stop comes off with an ordinary nail polish remover, exactly like a clear polish — there is no special remover and no soaking required. You remove it before every reapplication, which on this course means every two days. If a trace of bitterness lingers after removing, wash your hands with soap and it goes.

Question 25

How long should I keep using it, and what happens when I stop?

Accepted Answer

MAVALA’s own instruction is to continue until the biting has ended — the structured version of that is the 33-day plan, roughly sixteen applications. Stopping early is the most common reason the habit comes back, because the bitter taste interrupts the reflex but it is time that dismantles it. If biting returns weeks or months later, restarting a short course is normal and does not mean the first one failed.

Question 26

Where can I buy Mavala Stop in Canada, and how much is it?

Accepted Answer

Mavala.ca is the official MAVALA Switzerland store for Canada, shipping to every province including Quebec, in Canadian dollars, with free shipping on orders of $74.99 and above. Mavala Stop comes in a 10ml and a 5ml bottle; current pricing is shown on this page. Customer support is available in English and French.

Question 27

Which is the most bitter nail polish — is Mavala Stop the strongest one?

Accepted Answer

No bitter nail polish publishes its denatonium benzoate concentration, so no honest ranking by bitterness exists — anyone claiming one is guessing. What separates products in practice is not peak bitterness but whether the bitterness survives two days of hand-washing and typing, and whether the finish is discreet enough that an adult will actually keep wearing it. Mavala Stop dries clear and without a shine, has no fumes, and can be worn over coloured polish, which is why it tends to be completed rather than abandoned. MAVALA has made it in Switzerland since 1959.

Question 28

Does Mavala Stop smell, and does it expire?

Accepted Answer

It gives off no fumes and has no added fragrance — the faint solvent note on application is the clear lacquer base drying, and it goes within a minute. Like any nail lacquer it keeps best tightly capped and away from heat; if the liquid has thickened in the bottle it has been open a long time, and a MAVALA nail polish thinner restores it rather than a remover, which would ruin it.
