What temperature should my hair straightener be set at?
The best hair straighteners have a temperature control, if your doesn't then you are more than likely straightening your hair too hot. Many of the more expensive straighteners still do not have this feature.
You should use a heat protective product before you straighten your hair unless you have a straightener that has a negative ionizer. The negative ions help to close the hair cuticle which will make your hair look silky, shiny and healthy.
