In my opinion the French Crop is going to be THE haircut for men this summer. It is characterised by a long top and blunt fringe, short and sharp, sides and back. This haircut can be achieved by a fade or undercut, or even a combination of the two. My personal favourite is a fade or a skin fade if I can have my way.
The blunt fringe (if that’s your thing) can be short if you have the correct hairline and face shape for it, or alternatively if you need to have it a bit longer, that will also work for this look plus it will give you a bit more versatility. You can slick it back, mess it up or wear it very strong and striking forward.
