What are the current popular trends in men's haircuts and how to choose the right style for your hair type and face shape?

I don't change my haircut often. I don't really care what I look like and I don't really follow fashion. But my new girlfriend pays a lot of attention to it. It's important to her that I look cool and neat. So for her, I decided to change my hair and found this page Edgar Haircut https://glaminati.com/edgar-haircut/ . Guys, maybe for you who are like me and do not understand the trend hairstyles this will be useful.
