The five base face shapes
Oval: balanced ratio, the easiest to flatter. Round: low width-to-height ratio, soft contour. Square: prominent jawline, strong angles. Heart: wide forehead, narrow chin. Long: tall ratio, length over width.
There's no "best" face shape — every shape has hairstyles that suit it. Looksona's goal isn't to grade your face; it's to tell you which haircuts your face shape is most likely to amplify.
How Looksona detects face shape
We estimate face_width / face_height / jaw_width / forehead_width ratios from facial landmarks, then apply a stable rule set. Confidence-thresholded: when the signal is weak we return "unknown" rather than guess.
