A heavy bang is a type of haircut where thick bangs are cut into the hair. These bangs may be blunt, and cut straight across the forehead, or they may be sideswept and slightly angled off to the side, which tends to be a less severe look. Typically, when a heavy bang is cut into the hair, it is blunt cut. This style is more popular with women.
A heavy bang differs from a thin bang simply in the amount of hair that is cut short. Typically, to cut bangs, the hair is brushed down in front of the face from the center of the head. Clipping hair that is from the front of the head, near the forehead, will create a thinner bang. Conversely, clipping more hair and going further back on the head will lead to a heavier bang. A hairstylist will generally start with a thin bang to see how it looks before clipping too much hair.
A heavy bang is a very trendy hairstyle, and this style of bangs is typically longer than a thin bang. While thin bangs look good shorter or sideswept, heavy bangs typically fall below the eyebrows, slightly angling to follow the natural curve of the eyebrows at the temples and side of the head. Following this curve will give bangs a more mature appearance, as bangs can often make one look much younger.
Some face shapes look better with bangs than others, particularly with a heavy bang. In general, those with an oval or rectangular face will look best with a blunt-cut heavy bang, while those with a heart-shaped face might look best with a sideswept bang. People with particularly round or square faces, which tend to be very symmetrical in shape, may want to avoid bangs altogether as they can make the face look even more boxy.
Keep in mind that blunt, heavy bangs require more maintenance than most any other hairstyle. People with curly or wavy hair may need to straighten their bangs every day in order to get them to hang properly. In addition, bangs will require regular trims, typically every two weeks. Some hairstylists do not charge for regular bang maintenance, and will only charge for larger six-week trims, but other stylists may charge for each trim, which could get expensive. Keep in mind that it is very challenging to trim one's own bangs, and a mistake can take months to grow out, which generally means months wearing of barrettes, headbands, and hats.
