Q:I straighten my hair every day, and I don't intend to stop, but it's getting dryer and dryer. What can I do?

A: Condition your hair! And before using the flat iron, comb a leave-in conditioner or heat-protective product through evenly. You need a product that will help to protect your hair from hot styling tools. If you have to put heat on your hair everyday, products like these are really effective for maintaining your hair's health.
