Article: A diffuser attaches over the nozzle of your blow dryer. These lower the air flow, keeping your curls intact instead of creating a mountain of frizz. If your blow dryer didn't come with a diffuser, buy a "universal" model, or a diffuser specifically meant for your blow dryer. Just as described in the basic method, you should blow dry while your hair is damp but not soaked. Apply heat protectant before you begin, plus hair serum or oil if you want added shine. Curly hair is especially vulnerable to heat damage. Reduce heat to low, or over time you might end up with limp, straight sections in the middle of your curls. If your hair starts to break easily or looks damaged, take a break from heat treatments. Use the cool setting on a blow dryer, or air dry instead.

What is a summary?
Add a diffuser. Wash and apply products. Reduce heat.
