Stop 'N Grow Nail Biting Deterent

Stop 'n Grow stops nail biting and is invisible, colourless, odourless and it tastes terrible. It tastes so terrible that, within three weeks, most nail biters will be well on the way to losing the habit.
Applied over the entire nail and cuticle after breakfast and bedtime, the nasty taste keeps on right through the day or right through the night.
It is important that the nail biter continues to use Stop 'n Grow for at least three months after the habit has been broken.
