Shake the bottle before use. Apply over the entire nail and cuticle after breakfast and at bedtime. The nasty taste keeps on right through the day, right through the night. Replace cap securely after use. Stop'n Grow is recommended for adults and children over 2 years of age. May be used on younger children, but care should be exercised so that formative self-feeding patterns are not disrupted by association of the bitter taste with foods.
IMPORTANT - Continue to use for at least three months AFTER your nail biter has broken the habit.
