Seriously she looks at least twenty years younger with the shorter wig. With the shorter wig she looks like a grandmother with the longer wig she looks just like a mother.
According to
In Touch when Melinda Doolittle started with the show she was wearing her own wigs, but the American Idol hairstylist bought her a new one and the years just came off. The hairstylist had this to say about the wigs, "The higher the quality, the more realistic and more wearable it is," he said. "There are some good synthetic wigs, but you can't style them with hot tools because the fibers will melt." So he added some layers to the one and as you can see it really made a difference. Now if only he could get her a neck.
