Weekly Haircuts Keep Hair Short and Tidy
Men with military-short hair who prefer to maintain a close-cropped style should have their hair cut every one to two weeks, depending on how fast their hair grows. Maintaining this style requires regular maintenance, although if the look is simple it can often be done at home using a trimmer.
Longer Styles Require Less Upkeep
If you prefer your hair longer, you can allow more time between cuts. An average time may be between four and six weeks, again, depending on how quickly your hair grows. Men with long hair can go as long as six to eight weeks between cuts. At that point, split ends start to appear.
Individual haircut timelines vary based on the hairstyle and how quickly that person's hair grows. Keep track of how long it takes for your hair to grow out and you can quickly develop a routine.
