 If your hair gets damaged often, dietary supplements such as niacin and biotin can help. However, you should never take supplements without consulting your doctor. You want to make sure they're safe for you given your current health and will not interfere with any existing medication., Flat irons can damage hair from overuse, so do not flat iron your hair too often. Save the flat iron for special occasions, such as a night out, rather than using it as a part of your daily hair care routine., Allow your hair to at least partially air dry.
