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.

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

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

Mike

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

Been Chronically Chewing My Nails Longer Than I Can Remember

"I Am 26. It Is Such A Hard Habit To Break! I've Only Had To Actually Apply It 3 Or 4 Times In The Last 2 Weeks Because Of How Well It's Working As A Deterant For Me! If You've Struggled With Kicking Biting, At Least Spend A Few Bucks To Give It A Chance!

I Highly Recommend This Product!

I Highly Recommend This Product! It Dries Quick, Not Thick. You Cant Tell Anything Is On His Nails After Application (I Was Afraid It Would Look Shiny But It Doesn't.) It Tastes Nasty And It Will Work!

- D. Murphy(1 Days Ago)

I Bought This For My Habitual Thumb-Sucking Two Year Old...

"I Bought This For My Habitual Thumb-Sucking Two Year Old... I Just Put A Dab On Both Thumbs Right Before Bedtime. She Had No Problems With Sleep. I Applied It One More Time The 2nd Night, And She Hasn't Sucked Her Thumb Since! Great Product!

FREQUENTLY ASKED QUESTIONS

Is this easy to apply?

Yes, NIXXIT is very easy to apply. For the pen, twist the base until a small amount of solution comes out, then brush around the edge of the nail and cuticle. For the bottle, simply unscrew the cap and use the brush to apply a light layer to the nail edges. A little goes a long way, and it dries quickly.

What are the ingredients of this product?

NIXXIT is formulated with a safe, gentle blend of ingredients designed to help stop nail biting without harsh chemicals. Our formula includes:

– a clean, skin-safe base
– a gentle preservative used in skincare
– supports product stability
– naturally derived conditioning agent
– plant-based emollient for smooth application
– plant-derived thickener
– one of the world’s most bitter substances (key deterrent)

NIXXIT is free from parabens, formaldehyde, artificial dyes, and added fragrance.

Is there any smell to the product?

NIXXIT is virtually odorless. We’ve intentionally avoided strong scents or artificial fragrances, making it suitable for sensitive noses. Once applied, it dries quickly and leaves no lingering smell or gloss finish.

Can I purchase the product at any retail stores?

NIXXIT is currently sold exclusively online through our website, Amazon and Walmart. We do this to keep prices low, ship directly to you, and ensure you’re getting the freshest product possible. If you’re interested in seeing NIXXIT in retail near you, let us know!
