Review: Works great, just as described - My wife has a terrible anxiety habit of biting her nails until they bleed and it was her suggestion to try this out and it worked. She doesn’t even realize when she’s doing it * Subconscious action (in the past) but now with the stuff on her hand, she realizes it and realizes quick and stops biting 5 stars
Review: Disgusting and long lasting! - Thumb sucking? This nasty polish never heard of it. 10/10 tastes so bad and the taste last so long I only had to apply once. My daughter is 16 months and a comfort sucker, her thumb is so rough and dry due to this I tried gloves first but as soon as the glove came off to clean, the thumb went back in. Downside to this the first day it was so strong and she was trying so hard to suck her thumb she started drooling bc it tasted so bad and eventually threw up a bit because of it. And the taste transferred to cups from her mouth for two days so i kept washing the cups and gave her a wet rag to get the taste out. After that she hesitated to put her thumb in her mouth and a week later her thumb isnt even a thought. She switched to blanks for comfort. Use with caution, apply lightly!

### ⭐⭐⭐⭐⭐ Worked for thumb sucking
*by D***A on March 7, 2026*

Worked well to break the thumb sucking habit for my son! Tried it on my nail first just to understand how it would taste. First day he was inconsolable and by the second day was some whining and by the third day it was a thing of the past! Reapplied every morning, lunch time, and evening time before bed.
