Deciding which hairstyle to take on is a difficult decision since it can completely alter one's appearance. But the question is which hairstyles are popular now and which styles will make you look like you've been the victim of a hairdresser's bad day?

Here are the latest men hairstyles to go with different hair lengths.

Short hair looks classy and sophisticated, not to mention easy to care for during the hot summer months. A nice clean cut can make a man look mature and sophisticated, while on others it may do just the opposite, making them look younger.

For those with short hair, here are three things you can do:

1. Try pushing your bangs forward- the Caeser cut- as actor George Clooney has been seen doing.

2. Gel your bangs upward (not at a 90 degree angle!) and back, in more of a diagonal, by using gel or paste.

3. Make your hair look "spikey" by using hair gel or similar products.

Long hair for men is in style these days but long meaning not much longer than shoulder length. This relaxed hairstyle exudes a carefree attitude and is easily manageable as it requires nothing more than a good combing after a shower.

The only disadvantage of this hairstyle is that your hair may get annoying and it may not be comfortable having it fall in your face.

Constantly adjusting your mane behind your ears may make your hair greasy-looking. It may also not be a hairdo for those working in professional fields such as medicine, law or business.
