Summarize the following:
To straighten your hair, you'll be using a flat iron to apply heat to take out the waves in your hair. You should consider using a ceramic iron, as non-ceramic ones can damage your hair more easily or cause it to revert back to normal. Including your flat iron, you'll also need:  Flat iron Hair clips or ties Hair spray (optional) Hair straightening product (cream, mousse, etc.) Heat protectant Volumizer (optional) Flat irons come in many varieties and price ranges. You might have a simple flat iron with only high and low settings, or a space-age iron with a digital display for temperature. Temperature variable flat irons, where you can more precisely adjust the temperature, are an investment you will not regret, as these allow you to apply the right heat setting to your hair with greater accuracy, yielding better results. Flat irons come in different sizes for different purposes:½" Flat Iron: pixie cuts and bangs1" Flat Iron: short and fine hair1¼ Flat Iron: shoulder length and/or medium thick hair1½" Flat Iron: thick, coarse, curly hair shoulder length or longer2" Flat Iron: very long, very thick hair Tangles can make it difficult to separate your hair for straightening. Tangles can also make it difficult to keep straightened hair separate from the hair you've already straightened, which is important as straightening your hair too much can lead to damage.

Summary:
Gather your hair straightening products. Choose the right flat iron for your hair. Brush your hair so that it is ready for styling.
