Onyx Professional Stop the Bite Nail Biting Prevention Polish, 0.5 Fl Oz - Made in USA, Stop Nail Biting, No Bite Nail Polish, Thumb Sucking Deterrent

TLDR - It works very well. Will make you more mindful about where you place your fingers and you will stop with minimal effort. I have been biting my nails for my entire life over 30 years and this product works on the first application. The taste is quite awful and is so powerful if you even touch your nails to your lips. It does linger for a long time as well, reminding you that you placed your nails near your mouth. Taste is similar to gasoline and burning electrical wires. Super nasty. I have tried other similar products and I am not sure if it's just me or the product, but they didn't seem to be that strong or taste that bad and I would eventually bite right through it. I have been placing this on for over a month and haven't bit since the first application. My nails are getting their "White Tips" which I honestly don't know if I have ever seen before. I feel more confident about my appearance than I have ever had in my life and I am not trying to hide my nails while meeting with people. It's such a simple product and yet has a profound effect on my life. I wanted to include a few pointers for success that I have found helpful for anyone starting out. - Don't use too much per application. I found that if you wipe the brush on the rim of the bottle to remove excess polish, you can still get a good application and this will cut down to the polish transferring into handheld foods (I like pizza so this was a big lesson) -Wear gloves if you are prepping food. If you do some baking (I like making bread and kneed dough) or anything with direct contact to food, wear gloves to protect your food from contamination. -Make the application of your nail polish routine for best results. If you want to have the best success, apply once every 1-2 days to make sure the taste stays strong. For me, I found that applying the polish right after the shower makes it routine. Find out what makes sense for your routine. Hope this motivates you to give it a try and kick a nasty habit!

The nail biting polish was easy to apply. It does have a bad taste (which is the purpose) so it really will keep your hands out of your mouth. I will post an update on my nails/ photo in a few weeks to see how its been working. Only thing to share is if you have kids or anyone in general, the taste can transfer to them. Just be mindful about that.

I have chewed my nails since childhood, but as I approach my thirties, I began to notice bottom front teeth damage from my awful habit. In an attempt to stop denigrating my teeth, I bought this. It definitely works. It went on clear over my painted nails and dried quickly! But do not make the mistake I did and apply this stuff on the underside of your nails. The taste is extremely bitter and will instantly remind you to STOP putting your fingers in your mouth. HOWEVER, this also happens if you eat a chip, a piece of fruit, or any snack you've handled. With one application of the polish, this goes on for DAYS. I'm on day 4 of my first application of the polish and the taste and strength are still there, only slightly faded, and I wash my hands many times a day. You definitely don't need to apply this multiple times a day as the packaging states and as I previously mentioned, don't apply it on the underside of your nails, it is not necessary! The bitter taste will get under there regardless. My major problem is that the awful taste gets on my lips, and it's hard to get off. I find myself scrubbing my lips with a tissue or my shirt to get the taste off which has dried out my lips and made them a little rough. On the bright side, this stuff is long-lasting and supposedly, non-toxic. I have not chewed my nails, only attempted to do so, so that's a win! I will keep using it! Consider using some mini tongs or chopsticks when eating finger food, it will save you a lot of trouble. :)

This product really works! It has a clear, non-toxic formula that discourages nail biting without a harsh taste. My nails have grown stronger and healthier since I started using it, and it’s easy to apply and dries quickly. Highly recommend for anyone trying to break the habit.

I have bitten my nails for about 20 years, started as a habit when I was very young. Decided to try this product as I was tired of my nails looking ragged and horrible all the time. This product is fantastic at cutting your habit. I am 1 week in, using this product twice a day, and not bitten my nails at all. I would bite subconciously when I was on the computer or watching a movie and now, this product reminds me to stop whenever i bite. It tastes absolutely FOUL, which is the point of the product, but it is seriously nasty and the chemical taste lingers for a while. The only problem is that this can transfer onto foods you are eating with your hands, like a packet of crisps or slice of toast, so you need to be careful. Also, if you put this stuff on your nails, you NEED to remove it after each day of use, as the potency drops off considerably after around 6 hours, and putting layers over layers of this stuff on your nails looks pretty nasty. Removes very easily with nail varnish remover. All in all, wonderful product that I am confident will curb my habit.

I ordered Stop the Bite on 7th September 2025 and received it on 13th September. I’m writing this review today, 14th October — exactly one month since I last bit my nails. Nail biting has been my biggest regret since childhood, and I tried to quit many times but always failed. This time, I applied Stop the Bite only 3 to 4 times in total (not even daily), and it genuinely helped control the urge. More than the product, I realised that strong motivation and determination are the real key. If you truly decide to stop, this product gives you the push you need.

يجلس يومين كانه مناكير شفاف والطعم مرررر جدا لكن طاح وانكسر من اول يوم

I don't usually write reviews but decided to for this product because of it's effectiveness. My 3 year old has been sucking her left thumb since birth to the point where a small bump developed on that digit. Also, the dentist indicated that her thumb sucking could affect her teeth, even if she does not have her permanent ones yet, and further research revealed that it could lead to speech problems, she already couldn't pronounce "spoon" properly, it sounded like "stone", not sure if that may have just been due to her age. I looked up the chemicals in this product and most seem to be naturally occurring, if not exactly benign, but I was mainly looking for any reference to carcinogens, which I did not see, so I ordered a bottle which arrived within 2 weeks. We applied it to her thumb nail, she thought it was nail polish. When she put the thumb into her mouth, she started complaining, more like a fake cry, and asked for water. When that didn't help, she put a paper towel in her mouth for perhaps 30 minutes. I put some on my nail to try it, and although it's unappealing, a combination of bitter and pungent, I thought that she may overcome her distaste. She did not suck her thumb for the rest of the first day and only tried to suck it once on the second day. I think she tried on day 3, but mostly out of reflex. Surprisingly, she has stopped and we've not had to reapply since the second week.

Lo uso para mis niñas que no yerran las uñas y no lo hacen por que el sabor de el sleemalte es horrible.
