Nail biting is a nervous habit, which can rapidly become uncontrollable.
It has a bitter yet harmless taste and the appearance of clear enamel. Helps break the nail biting habit and thumb sucking. Works for children (more than 3 years old) and adults.
Apply a coat over the entire nail (or polish) and allow to dry. Repeat the application every two days. Continue the treatment until nail biting has ended.
Never wash hands immediately after application.
