Onyx Professional Nail Biting & Thumb Sucking Treatment Cure Polish That Enhances Nail Growth 0.5 fl oz

This product works great to stop thumbsucking fast! After the first application my toddler had his fingers out of his mouth and by the third day he stopped 'testing' to see if they tasted bad. I only ended up applying the polish for a week to solve our constant thumb sucking problems. It dries fast and doesn't smear like normal nail polishes. It's been a couple weeks now and I can confidently say our problem is 100% solved!

Used it for my son who sucks his fingers, put it on within a few days no more fingers.

Didn't work at all. My 6 year old daughter just said it tasted like she had her nails painted.

Gross. She would kiss mama. Then my wife would kiss me(which would taste awful.) We should not submit our kids to this crap.

I bought this for my ten year old daughter. She has bitten her nails even since she was little. The result has left her cuticles and nails in really bad shape. I bought this at a VERY reasonable price. She has had it for a week now and I can already see improvement. She actually has some nail growth which is very cool to see (for her). It's a good product to have. She says that when she "accidentally" puts her fingers in her mouth, it taste so bad that she instantly removes them. I've tried other products and have not seen these results, so I am very happy! The picture I included is only a couple of days after applying it. (Sorry, nails are dirty - she just came home from school and needs to wash hands and nails), but you can get the general idea.

This stuff works like a charm!

Worked great until my daughter got used to the taste now it's useless. :P

This stuff works great for my son.
