Is Your Hair Routine Wreaking Havoc on Your Locks?

2. Poker-straight strands

You hate to love it. The straight iron. Even though you abandoned your scene-kid persona in high school, the straight iron remains an integral part of your styling toolkit. Every time you use it, your strands hiss and fall limp like a moth in a bug zapper. Rather than frying your hair with an iron, commit to a few extra minutes with an ionic blow-dryer and ceramic round brush. Always use a thermal-protection spray before, and minimize damage with your dryer's lowest heat setting. To lock it in place, finish with a burst of cold air and a drop of argan oil.
