Which hair straightener should you use if your hair is thick frizzy and curly?

One suggestion for a straightener is a "Conair Platnium" flat iron. Another one would be "Chi Flat Irons" which are usually very thin in width and that helps with making hair more defined and straight compared to the thicker flat irons. If you do use the Chi flat irons, part your hair and only use little bits of hair at a time when straightening it. This way the straight hair would last longer.

Another contributor suggests using a Remington T/Studio as your hair will stay straight until you take a shower again.
