One of the most common desires for people seeking information about hair styles is what to do when you have a "long" face. This is particularly an issue with some people who have really proportionately large foreheads. There are a lot of options for someone who has this particular problem. Someone with straight hair can create the appearance of more width by using bangs.
Chin-length bobs and cuts can also be effective options because they also work well to create an effective illusion of width. Curls and waves also add width, but for general appearance sake it might be wise to avoid short layers that add volume on top. Bangs can make your face appear shorter because they cover up large foreheads. While these are all positive options, there are some styles that you will need to avoid.
Any type of style that involves extremely long hair or extremely short hair will end up elongating your face, which you are looking to avoid in the first place. If a long face is not a problem, you may want to consider looking for a style that involves long, curly hair. There are very few looks that turn the head more than long, curly hair. If you are a girl with long curly hair, and you are having trouble with "frizzing," one way to stop that is to not brush your curls. Take the time to use your fingers to break up curls, or you will continue to have the problems you are already facing.
There are many magazines and e-zines dedicated specifically to these types of hair care topics.
For each person, there is a different style. Find pictures, and try to imagine each look on you. Does it accentuate your best features? Does it hide the worst? Do you like it? That is the best and most important decision. If you like your hair, your attitude will show and it is attitude that attracts other people's attention more than anything else. Remember that, and if you find a style that works in your eyes, it will work for everyone else, as well.
