There are a lot of ways to fix frizzy hair on men. You can learn from the mistakes made by the guys in the past to avoid the same problem in the future. Here are some of the things that you can do to fix frizzy hair on men: You must cut your hair regularly – at least four times a week – and deep condition it to prevent frizz. If you have curly hair, you can keep it longer than usual but you must cut it shorter. Otherwise, you should take a trim every other week. This will help keep your strands from getting too wavy and making them look more prone to split ends.
