Apply in a single stroke for a quick touch-up. Use only on scalp hair, not on eyelashes or eyebrows. Avoid contact with eyes; if contact occurs, rinse thoroughly with water immediately. Do not use on damaged or irritated skin. Stop use and consult a dermatologist if irritation occurs.
Avoid contact with clothing, hats, walls, carpets, floors, and fabrics, as stains may be difficult to remove. Keep away from flames, direct sunlight, and high temperatures. Store out of reach of anyone at risk of accidental ingestion, including children.
