Straighten Short Hair

A: Sure you can straighten short hair with a flat iron, and in fact keeping it straight will usually require a flat iron. You just have to choose the right iron. The shorter the hair is, the thinner you want the heating plates to be.
Just go to a beauty supply shop and look for a good-quality, narrow flat iron. Look for one with an adjustable heat setting and an automatic shut-off for safety. Unless you're already familiar with using a flat iron, you will want to give yourself some practice time to get used to it. And even if you know the ins and outs of flat iron straightening, expect a learning curve for dealing with your new style.
Also, remember to use a good conditioner and a thermal protectant to keep from damaging your hair. You'll also want to look over our thermal styling article.
