Do not use a curling iron, hair dryer, or other heat styler on treated hair. Warn children to stay away from open flames, lighted cigarettes, and electric heat sources while the hair is wet.

Do not allow a child to use Ovide without help from an adult.
Wash all clothing, hats, bed clothes, bed linens, and towels in hot water and dry in high heat. Dry-clean any non-washable clothing. Hair brushes, combs, and hair accessories should be soaked in hot water.
