A lot of cheaper curling irons will not do this with my thick, unruly curly hair, without using a flat iron first.
Yes, but how do you know this before you buy one?
I did some research and ended up buying a Conair tourmaline ceramic. I also have thick wavy (fluffy) hair and it seems to me it did what it supposed to. How can an iron work on one head of hair and not the other, if the temperature is the same?
