2. SEDU DOES WHAT?

A straightening iron simply heats up and straightens the hair just like a curling iron does with curls. The Sedu is two ceramic plates that heat up and 'squish' the hair in between those two plates, and then straightens as the lock of hair is passed slowly between them. The Sedu is made of the two ceramic plates because ceramic heats evenly, and doesn't damage the hair as much as metal does.
