I’ve been biting my nails since I was a kid. Thought I’d never stop. NIXXIT made it easy. First time I’ve seen white tips in years.

Ryan

Megan S. ⭐⭐⭐⭐⭐

Honestly didn’t expect it to work. But after just a few days, I noticed I wasn’t biting anymore. Super simple and effective.

Sarah

Ryan p. ⭐⭐⭐⭐⭐

I used to bite without even realizing it. NIXXIT helped me become aware. It’s gross enough to stop you but not unbearable.

Mike

Lindsay A. ⭐⭐⭐⭐⭐

I tried bitter polishes before and they didn’t do anything. NIXXIT was different. Helped me break the habit in under 2 weeks.

Jennifer

Years of anxiety-driven nail biting—gone. This stuff really works. It’s been 3 weeks and I haven’t touched my nails once.

NIXXIT

THE BEST NAIL BITING TREATMENT

HOW IT WORKS

Twist . Apply . Let Dry

  • 1. TWIST

    Give it a twist until the liquid reaches the tip. It’s ready when you see a drop!

  • 2. APPLY

    Brush a thin layer onto each nail—just like nail polish, but with bite-stopping power.

  • 3. LET DRY

    Hands off! Let it dry for 30–60 seconds before touching anything.

KIDS HATE IT. PARENTS LOVE IT.

The bitter taste stops the habit fast without fights, mess, or glossy residue. Clear, odorless, and seriously effective.

SAFE FOR LITTLE HANDS.

We spent years perfecting a formula that’s both effective and safe for kids. No parabens, no harsh chemicals—just clean, worry-free habit-breaking.

CUSTOMER REVIEWS

Worked After A Few Days, Not Right Away

"My son didn’t stop biting right away. We used NIXXIT for 3 days straight and he was still sneaking bites when I wasn’t looking. But by day 4 he started catching himself and saying 'eww' every time he tasted it. It’s been a week and he hasn’t bitten since!"

– Lindsey F.(2 Days Ago)

Stopped Thumb Sucking Cold Turkey

"I honestly didn’t think anything would work. My 3 year old was a thumb sucker for life. I dabbed a bit on at nap time and again before bed. She whined a little the first day but stopped sucking by day two and hasn’t even tried again. So thankful!!"

- Angela R.(1 Days Ago)

We Had To Stick With It For A Week

"We almost gave up after 2 days because my 7 yr old said it didn’t taste bad enough. But then I gave it one more go and by the end of the week, she was telling ME not to forget to put it on. Her nails are actually growing now!"

– Karla S.(4 Days Ago )

We Turned It Into A Game

"My daughter was hesitant at first so we made a calendar and gave her stickers for every day she didn’t bite. This stuff helped her actually break the habit. Took about a week but she’s officially bite-free!"

Author Text– Nina K. (4 Days Ago)

One Use And It Worked!

"My daughter stopped biting after the first time we used it. She hated the taste and hasn’t gone near her nails since. I honestly thought we’d have to fight her on it but she’s been proud to show off her hands!"

– Brianne W.(3 Days Ago)

Tried Everything—This One Stuck

"My 6year old bites constantly, even in his sleep. We’ve tried gloves, bitter polish, and bribes. This is the only thing that worked. Took about 5 days of consistent use but now it’s part of our bedtime routine and his fingers are finally healing."

– Matt C.(3 Days Ago)

The Importance to Stop Nail Biting & Sucking at a young age

  • Keeps Germs Out

    Kids’ hands touch everything. Nail biting brings dirt and bacteria straight into their mouths—raising the risk of illness.

  • Prevents Pain & Infections

    Chewed nails can lead to painful hangnails, bleeding, and even skin infections around the fingers.

  • Builds Confidence

    Many kids feel embarrassed about their bitten nails. Helping them stop can boost their self-esteem and how they carry themselves.

  • Stops Thumb Sucking Too

    Our formula also helps with thumb sucking—breaking habits before they cause long-term dental or speech issues.

FREQUENTLY ASKED QUESTIONS

How long does it typically take for NIXXIT to work with younger children?

Results can vary. Some children respond immediately to NIXXIT’s bitter taste, while others may need a few applications. If you find that NIXXIT isn't working after several uses, please stop using it and reach out to us. We’d be happy to help explore alternative solutions for your child.

Is this easy to apply?

Yes, the product is very easy to apply. You twist the pen until a little bit of the solution comes out then brush a small amount on the outside edge of the nail/ cuticle. Remember a little goes a long way.

What are the ingredients of this product?

Water, Phenoxyethanol, Benzoic Acid, Ethylhexylglycerin, Glycereth-2 Cocoate, Hydroxyethylcellulose, Denatonium Benzoate

Is there any smell to the product?

NIXXIT is completely odorless, allowing you to apply it discreetly without any unpleasant or chemical smells, making it ideal for everyday use.

How old do you have to be to use NIXXIT?

We recommend NIXXIT for ages 3 and up. Younger children may not fully respond to the bitter taste, as their taste buds are still developing.

Can I purchase the product at any retail stores?

Currently, NIXXIT is only available online through our website, Amazon and Walmart. While we're not in physical retail stores yet, we’re actively working to partner with more retailers to bring NIXXIT to stores near you soon!
