There was a time when celebrities were the only women who wore -- or could afford to wear -- hair weaves. Back then, the fact that the hair on their heads didn't actually grow out of their scalps was a hush-hush affair. Not anymore! Today, many women experiment with hair additions in every length, color and texture. Instead of simply being a way to add inches and volume to your style, hair weaves have become a way to introduce variety to your style repertoire. Plus, there are some useful benefits to wearing hair weaves. Weaves are designed to be worn for a short amount of time, anywhere from one day to a couple of months. Unlike a haircut, which you have to wait on to grow out, hair weaves are low commitment options.
