It turns out anyone with heated rollers, a tail comb, and some texturizing spray can get that red carpet-level hair tuck easily. In a video for Access Hollywood, celebrity hairstylist Chris Appleton went through the process in detail.
It all starts with some large, heated rollers. According to the celebrity hairstylist, you should wrap them in and leave them there for ten to fifteen minutes. Then, take them out, add a bit of texturizing spray, and brush out the curls. The result should be "sexy, effortless, bombshell hair" which, as Appleton emphasized, "never goes out of fashion."
One of the most important steps is using a tail comb for a precise middle part. "Middle parts are very beautiful and soft and flattering," Appleton explained. He added that it gives off a more "youthful appearance." The final touch to imitate Lopez's Grammys hair is simply tucking the front sections of your hair behind your ears.
