It tastes bad enough to stop you mid-bite. And grows your nails in 14 days. Long enough for someone to actually compliment them.
4.8 stars from 56,200+ women growing nails they used to bite
Why stopping never sticks
You have quit dozens of times. Here is why it always restarts. And what finally breaks it.
Stress. Boredom. A rough edge. Your hand goes to your mouth before you even know it.
By the time you realize, a nail is already gone.
The length you built? Gone in seconds. Now there are more rough edges to bite.
Willpower. Gloves. It works for a few days. Then one bad moment and you are right back.
Same guilt. Same promise. Same trigger two days later.
One swipe interrupts the bite. And grows your nails long enough for someone to notice. That is the whole idea.
