<p>Long, straight hairstyles will never go out of style. In this gallery, I feature some of the best straight hairstyles on celebrities today.</p><p>To get super-straight hair, you&#39;ll need a blow dryer, a flat iron, and the right styling products. Which types you use are based on your hair texture. For curly hair, you&#39;ll want a straightening balm like L&#39;Oreal Paris Oleo-Keratin Smooth Intense Xtreme Straight Creme.</p><p>You can either blow dry your own hair or get it professionally done.

Layers add body. But make sure the stylist doesn&#39;t thin hair too much. And invest in a good thickening, volumizing spray or mousse. But a little will go a long way. Too much product will also weigh hair down.</p><p>Video: How to Get Blake Lively&#39;s Long Waves</p><p>Consider hair extensions. Not all hair extensions are a major investment.
