I would recommend that you only use your Straighter three or four times a week. And when doing so it is very important that you use a heat protector on your hair. Preferably one that re-activates when heat is applied. I would also recommend that when flat ironing your hair, take smaller sections so that the heat can penetrate more easily. And if you are going to straighten your hair more than the recommended amount per week, I would advise that you only go over each section of hair once as the heat can damage and dry out your hair.
