Natural Ingredients That Can Help Stop Nail Biting
Organic Aloe Leaf Juice Aloe vera is a natural moisturizer that can help to hydrate and soothe dry, cracked nails. Glycerin Glycerin is another natural moisturizer that can help to keep nails and skin hydrated. It can also help to soften brittle nails, making them less likely to break. Sodium Levulinate Sodium levulinate is a natural preservative that is derived from vegetables and starch. It is non-toxic and has a slightly bitter taste, which can help to deter nail biting. Sodium Anisate Sodium anisate is another natural preservative that is derived from anise and fennel. Hydroxyethylcellulose Hydroxyethylcellulose is a thickening agent that is derived from cellulose (main constituent of plant cell walls and of vegetable fibers). It is non-toxic and can help to create a barrier on the nails, making them less likely to be bitten. Denatonium Benzoate Denatonium benzoate is a bittering agent and what makes Strong Will taste so bad. Organic Eucalyptus Extract Eucalyptus oil helps to strengthen nails and the nail bed. Organic Ginger Root Extract Ginger root extract can help to strengthen nails and make them less likely to break or chip. Organic Wintergreen Leaf Wintergreen leaf extract conditions nails and surrounding skin. Organic Oat Kernel Extract Oat kernel extract is a natural skin cleanser that can help to remove dirt, oil, and bacteria from the nails and surrounding skin. Allantoin Allantoin is a natural moisturizer that can help to hydrate and soothe dry, cracked nails, and nail beds.

Customers say
Customers find the anti-nail biting pen effective, with one mentioning it worked well for a 5-year-old thumb sucker. The product dries quickly in a few seconds and is easy to apply, with one customer noting it doesn’t transfer to other items once dry. While some customers say it lasts a while, others report it wears off too quickly, and while some find it worth the money, others consider it unsatisfactory for the price. The taste receives mixed reactions, with several customers describing it as super bitter, and washability is also mixed, with some saying it washes off easily while others find it difficult to remove.

Works Great, Tastes Terrible,
My son has sucked his thumb since he was 4 months old when he is tired, upset, or bored. He is now 2.5, and the dentist suggested we get him to stop before 3 years old. I did a little research and decided to purchase this. By day 3 he was no longer sucking his thumb. I stopped applying it after 5 days. It has been 3 weeks and heâs still going strong.It does taste awful. I tried it so I would know what heâd be dealing with and quickly decided that water wouldnât be enough. I kept an applesauce pouch on hand and when he would forget and suck his thumb, I would give him a bit of apple sauce and remind him that he canât suck his thumb because itâs nasty.I had been avoiding this transition because I thought it would be such a long and painful one, but this product made it incredibly quick and simple.

Long-lasting
Iâm surprised how well this product works. I apply the solution to my nails in the morning after I take a shower. It dries almost instantly and it lasts all day. You canât see any residue on the nails. It doesnât feel sticky. The taste is really awful. Itâs a bitter taste that makes you immediately mindful your nail is in your mouth. Iâve tried other similar products in the past and it doesnât last or it looks gross. I just started using this so I canât say it fixes nail biting completely, but the product is great.

Effective, but not long-lasting
Overall, this is a good product, but having used more traditional nail-polish-type deterrants in the past, I found this to be less effective. I’m giving it four stars due to the application being very convenient and different, but the result was that I ended up biting my nails again more often, as I will explain.I am a lifelong heavy nail biter, and despite using deterrants for 2 years and trying very hard to curb the habit, it’s still a challenge. For the last 2 years I used Mavala stop nail polish, which has an intensely bitter taste and is basically a clear bottle of nail polish with bitter chemical added. As long as I keep this nail polish on, I can’t bite my nails. Although the polish is water resistant, it wears off in about 2-3 days and by the end of the second day, I may find myself putting my fingers in my mouth some and attempting to bite my nails despite remnants of the bitter polish still being there. This is where these deterrants all hit a snag for me. If I’m not diligent about keeping it on my nails, I go back to biting.Which brings me to the Nail Quail. I bought it to try something different. This product has a similar strong bitter taste, and the applicator is so much more convenient than the nail polish bottle. Initially I was extremely happy with the product because of how much more quickly I could apply it to my nails, and it dries fast too as it is water-based. However, also because it is water-based, I found that within a single day it has already washed almost completely off of my hands (I wash my hands regularly throughout the day, especially when I’m working). To use this effectively, I need to reapply it multiple times each day, instead of ~3 times each week. That doesn’t mean it’s totally ineffective, but for my case it isn’t perfect either.The shape of the product is like a marker, and I think it’s meant to be slipped into a pocket or purse to carry around and reapply when out and about. I haven’t done this, but I suppose I’ll need to start.If I could get a formula of this that was more water resistant with the same applicator tip, I think it would be just about perfect.

Effective Bittering Agent
I’ve been a nail biter for my entire life. My fingers would hurt all of the time because I couldn’t stop going after every little thing. So after a third of a lifetime of pain, I finally wanted to really truly stop. Combine this product with CBT therapy and motivation, I now have pain free fingers and long nails. It’s a glorious feeling. The bittering agent in this product is quite potent, and a great reminder to stop me in my tracks. I’m not sure about the moisturizing aspect being amazing, I still feel like my fingers are a bit dry, but they’re better than without. Also, I do have to reapply regularly, as it comes off kind of easily. Which isn’t so bad, as when I’m cooking I taste what I’m making with my fingers sometimes and don’t want to have the bitterant affecting my palette. Compare that to a bitterant nail polish. But it’s in a great compact package that I don’t mind having as a part of my EDC.

Effective but transfers to everything, wouldnât recommend
The pen itself is good quality, works well. The product goes on nicely & itâs easy to use. This is for my 10yo daughter, I bought this bc the one we usually used was out of stock. The major con & a reason I will be returning – it gets EVERYWHERE & ON EVERYTHING. I donât even know how. Even once it dries it transfers to anything you touch, food, drinks, it then gets in your mouth, on your lips, etc etc. If we hadnât already used a really good nail biting polish (doesnât transfer at all) I maybe wouldnât be returning this & assume this is just how it is. But itâs not, there are actual clear nail polishes for nail biting that donât do this at all. For this reason, I would not recommend.

Stopped me from nail biting
This product is amazing, honestly Iâve been biting my nails for 20+ years, and this product tastes so nasty, so rancid (tastes like taking a bite out of a bar of soap) and it is the BEST deterrent for me biting my nails. 10/10 recommend to anyone looking to break a habit!

My son is a anxiety nail bitter and also special needs and we had tried everything else out there to help to stop biting and let me tell you this stuff works!!! Unfortunately I can not find it to buy it again so he has gone back to biting. I needed up getting some on my finger without knowing and yup definitely nasty tastingð¤¢
