Only when you are young and carefree that you tend to experiment more with your hair and different styles. As you grow older, the tendency to stick to something that is tried and test seems paramount.
Another point to consider is the shape of the face. For a round face, opt for haircuts that cover the sides of the face a little. If the forehead is a bit large, then bangs are a good idea. Bangs are also great if you are looking for some stylish haircuts.
For Little Girls and Teenagers
Kids look cute with short hair. A bob cut is a good idea; however, you can also experiment with different styles of bob, to make the cut look different. A bob with a graduated effect or stacked effect, or a bob with stylish sweeping bangs, choppy bangs, or blunt Cleopatra bangs are good options rather than opting for plain blunt bobs.
Pixie, Mohawk, asymmetrical trendy haircuts, short choppy haircuts, layered, wavy styles, etc., are some great haircuts for teenage girls.
According to Hair Type
Choppy haircuts add a lot of volume, you can also consider getting lot of layers to add volume. Stacked haircuts also make the hair look voluminous.
If you have long hair, and are bored of just plain, long hair, then why not consider a new haircut to make your hair look chic. Layered haircuts with bangs are fairly popular these days.
So, consider the given factors before you get that chic haircut. You don't want to sulk later on, do you? To maintain the haircut you will need to visit the salon every 4-6 weeks, depending on the haircut that you get.
