There are several ways to figure out which haircut suits your face, including:
Face shape
You can trace your face's outline in a mirror or on a selfie to determine your face shape. You can also use an app like Face Shape Meter to take a photo or upload one and get an analysis of your face shape
Hairstyle considerations
Some hairstyles that suit different face shapes include:
Undercut: This cut can add structure and angular features to an oval face.
Pixie cut: A short haircut with volume and texture on top can work well with a diamond-shaped face.
Curly or wavy hairstyles: These can add width to the jawline and make a face shape less sharp.
Shag: A messy shag with lots of layers can add softness and dimension to a square face
