I have a sedu flat iron already and it's good and evreything at getting your hair silky slick straight with awsome bodie and movement but ... the plactic part on the outside gets wayyyy to hot to where you have to take a lot of breaks because your hand hurts from the heat,( i also have a lot of hair, and it's long,it goes to like my elbows.''Sedu" claims to be able to get your hair pin straight with one pass, and it doesnt ., while " Kiyoseki" claims to get it straight with one pass only, i've also seen it on either HSN or QVC i dont remember which one it was on. but it showed it going through all types of hair with one pass and it also showed it standing up to humidity. "Sedu claims to stand up to humidity aswell ( believe me, it doesnt ) , so i guess my question is "Sedu vs' Kiyoseki ceramic flat iron. which one works better for biracial hair?
