fwb needs a wig

Okay, my fwb has no hair. And it makes him feel self conscious , I want to help him. I've told him that he's hot with or without hair. I like him better without all the hair. He just looks so much better and you can actually see him face..... I was wondering does anyone know where maybe I can get a wig online and that will last awhile??  I've seen YouTube videos where these women have gotten some wigs and they look real.. can anyone help?  My fwb is a guy btw. lol.
