Begin with a 3-inch by 3-inch section at the scalp. If your hair has a lot of volume, start slightly smaller, as not to inhibit airflow in the Wand.
When held to the scalp, the Wand should reach all roots by gently moving the Wand Mouth across the section. No need to move the wand up and down the hair strands, keep it close to the roots.
*Should a section of hair be too large in volume, the Heat Chamber will shut down indicating the section size should be reduced. Simply remove the hair section and retry with less hair. The Heat Chamber will resume automatically.
