We recommend a lower temperature for fine, bleached and/or damaged hair and a higher temperature for curly, thick and/or hard-to-style hair. As each hair type is different, we recommend that you start with the lowest heat level first. If needed, you can gradually increase the cooking level with each additional use. 150-170°C (Green LED – Yellow LED) for fine, bleached and/or damaged hair. 170-210°C (yellow LED – red LED) for normal, colored and/or wavy hair. 210-230°C (red LED) for thick and/or very curly hair.
