You may be tempted to grab for those heat tools in the morning but they cause a lot of damage and you need to take steps to protect your hair from the heat and make sure that you give your hair a chance to recover from the damage.
Both hair dryers and straighteners can cause hair damage and should be used with care. Straightening is more harmful than blow drying because it is applied directly to the hair strand and actually burns the hair. If you are a lover of heat hair tools you should invest in a protectant spray or oil which will not eliminate the damage but it can help a lot.
