does all the ion (flat iron) ceramic?
no, i got a differ one but i forgot what kind it is.
OF COURSE NOT. BUT JUST BE CAREFUL FOR THE ONES THAT ARE.
Any of them are good IF they have high temperatures. The hotter the temp, the more effective it is. I have had a ceramic and the gold plate one. The only one that works the best for me is the one with the highest temp(500).
