1) Man bun
Man bun for straight hair is the most versatile look wherein you can easily manage the strays and also grab the perfect casually sexy style by pulling out some strays at the front from the bun. This style can be altered into a half bun or even a high top bun and either way it will bring out the raw sex appeal in you.
2) Long Mane
The long mane is the classic romantic hairstyle for men with long hair. All you have to do is let your luscious long hair grow out upto shoulder length at least and leave it be for the deep and strong style statement. This is one of the most intriguing styles and is truly a conversation starter.
The pompadour style is easy to achieve with straight hair whether your hair length is short, medium or long. It is much more effortless and natural for men with straight hair because it is truly easy to slick back and oomph up straight hair. This style is great when combined with a fade. Some men also opt for trimmed sides look which is again a great business style.
