VOLOOM is designed to be used solely on the under-layers of hair, specifically to create volume.
Unlike a flat iron or curling iron, you never pull VOLOOM through the hair, nor do you use it on the ends of your hair. You close and release it quickly on the hair near the scalp and underneath a smooth top-layer of your hair.
You only need to hold it there long enough to say “VOLOOM” and then release it. Close and release VOLOOM two or three times down the hair shaft to about eye or cheekbone level.
