How to straighten your hair without damaging them too much?

Even if you dont shampoo daily, condition your hair in shower daily! Then you could use a serum, or even a leave in conditioner After shower. My favorite serum is garnier fructis =] After hair is dry apply a heat protecting spray then flat iron away. Another tip is make sure you using a decent flat iron, the ion ones get hotter so you leave on hair less time causing less damage.
