A mandatory strand test must be performed 3 to 4 days prior to application, especially on blonde, colored, or sensitized hair. Avoid contact with the scalp. For blonde or fine hair, always use lower iron temperatures (up to 350°F \/ 180°C) and fewer passes to prevent damage. Do not apply to children, pregnant women, or lactating women. In case of contact with eyes, rinse abundantly with water. If irritation occurs, discontinue use and seek medical advice.
