First, there are the temperature settings. Obviously, different hair requires a different heat level. The thicker your hair is, the higher level of heat you should apply to straighten it. I highly recommend you to read the instructions which usually say what temperature you should select for your particular hair type. This may vary a little bit from one flat iron to another. The general rule here is the less heat you apply, the better your hair condition will be. And always use a heat protectant, regardless of your hair type.
I was happy the moment I got this its so smooth when you use it was abit caught off guard by the different power cord but that was quickly fixed but nonetheless I love this piece of a styler
The Glamfields straightener, like most of our top-ranked models, releases negative ions to fight frizz while preventing split ends and knotting. Performance, though, sets it apart from the pack. Hair is straightened beautifully and quickly with the unit’s metal ceramic heater requiring just a 40-second warm-up, eliminating a long wait for the brush to reach temperature. And speaking of temperature, there are 12 heat settings ranging from 250° (ideal for brittle hair) to 450° (hot enough to straighten extremely thick or wavy hair).
