You should have a triangle-like shape with the point a few inches above your hairline. The sides of the triangle should slope down along the sides of your forehead. Comb the triangle of bangs forward and pin the rest of your hair back or put it in a ponytail to keep it out of your face.

Try using a flat iron on dry bangs to make them straight. It’s important that your bangs don’t have any wave to them so you can make a straight cut. Keep in mind that doing this with dry hair will be more accurate, but it may also be more difficult. Mist your hair all over with water to get the best results.

If your bangs are damp, comb them gently to avoid stretching the hair. Cut them 1⁄2 in (1. 3 cm) longer than the desired length because the hair will shrink up when it dries. If you want your bangs to angle downward at the ends, cut straight across from the middle of one eye to the middle of the opposite eye. Once you reach that point, begin to cut at a downward angle. Move to the other eye and cut at a downward angle until you reach the rest of your hair. The angle can be as steep or as subtle as you like.

This creates a rounded edge on both sides of your bangs, so the bangs are shorter in the front and longer on the sides. [4] X Research source

You can also use thinning shears for this. [5] X Research source

If your hair is naturally curly or wavy, dry your bangs with a flat brush. Hold the brush close to your forehead and move it behind the dryer from roots to ends so you aren’t adding volume to your bangs.

You should now have a section of hair in the front center of your face that is separated from the rest of your hair. If you already have bangs, you should have a width already determined, so take your preexisting longer bangs and part them towards the middle, also separating them from the hairline.

Never soak your bangs or make them completely wet. Your hair is longer when it is wet, so when it dries it will be shorter. To avoid cutting bangs that are too short, try to cut your bangs with slightly wet or dry hair. If your hair is very wet before you cut your bangs, blow dry them until they’re 80% dry. When blow drying, make sure you are brushing bangs straight down, or in the opposite direction of your part. Don’t blow dry bangs downward in the direction they normally would lie. This creates a “rainbow effect” in which your bangs have a high arch to them. It’s difficult to cut bangs when they are like this, so it’s better to create some volume in the opposite direction.

If you aren’t sure how long you want your bangs, start by cutting at the tip of your nose and ending in a diagonal at the bottom of your ear. This will create long, side-swept bangs. Make sure you are using scissors specifically designed for hair, as this will give you the best cut. If you want shorter bangs, start near the top of the nose, in line with the eye, and cut at a downward diagonal towards the middle of your ear. Always cut bangs longer when you start off – you can always cut them shorter as you go, but you don’t want your first cut to be too short, because there’s no way to rewind from there. You can try cutting in 1⁄2 in (1. 3 cm) increments to make sure you don’t cut too much of your bang off.

If your hair is really thick or you want your bangs to have an even more natural look, you can use a razor made for hair or a hair thinning tool to thin out the ends of your bangs.

You can also blow dry your bangs in the opposite direction of where they naturally fall to make them lay flat and give them a bit of curl at the bottom. As they are close to being dry, flip them back over and blow dry as usual.

Tuck the rest of your hair behind your ears or pin it back with hair clips to keep it out of the way. [10] X Research source

Then, do the same thing on the other half of your bangs. Cutting at an angle creates the soft sloping edge of your curtain bangs.
