You'll stop biting right away!

This helped my daughter stop biting her nails (for the time being). I'll have to wait and see in the long-term if this will break her habit, but immediately after drying I heard her yelling and running to the sink for water to rinse her mouth out—so overall, I think it's effective!

Great nail biting deterrent

Product was easy to locate on the Walmart website. The price was reasonable and the product description was excellent. It arrived quickly from the seller and the best part is that it has been very successful with this health issue for me. THANKS very much. It applies easy, smells ok, is an excellent deterrent, and the applicator in the bottle reaches all the way downt to the bottom of the bottle. Excellent product.

Product Works!

I started using NIXXIT because I have a bad habit of biting my fingernails and the skin around the nails. Using this product was a way for me to try to break the habit. The polish is clear and dried really fast. I put on the product and I did try to put my nail to my mouth to bite it. It does have a bad taste when my nail hit the tongue. It made me put my finger away from my mouth. So the formula does work! I try to put on the formula daily and it has helped me to stop biting my nails. The product is helpful for anyone trying to break the habit of biting their fingernails.
