Alicia Keys has got a sophisticated and straight hairstyle along with high ponytail which gives her a great look. To get her hairstyle, first you must take a flat iron and use it on the hair to straighten it from the root to tip. Next take a smoothing cream and rub it in between the palms and run it over the hair to control the flyaways. Then brush all the hair and create a high ponytail and use elastic to secure it. At last apply a little amount of shine serum for the ends of the ponytail to get a sleek finish.
