Your geometry is the secret your stylist already knows. Here’s how to read it yourself — and let AI do the measuring for you.
Walk into any salon and a great stylist will tilt your chin, study your jawline, and quietly start imagining which cut will open up your eyes or soften a strong brow. They’re reading your face shape — the geometric blueprint that determines which styles will work with your natural structure, not against it.
Face Insight’s AI Hair Style Advisor brings that same analysis home. Using 478 facial landmarks from Google MediaPipe, the tool measures your face’s height-to-width ratio, forehead, cheekbone, and jaw widths in real time — then delivers personalized hairstyle and color recommendations instantly, privately, and for free.
Below, we break down all seven face shapes, the styles that suit each one best, what to avoid, and the feng shui color guidance that takes things a step further.
Know Your Face, Own Your Look
Oval
Round
Square
Heart
Oblong
Diamond
Triangle
All recommendations work with your natural beauty — not against it. Every face shape is genuinely beautiful. These are styling tools for harmony, not corrections for perceived flaws. The right cut doesn’t change who you are; it clears the way for others to see you clearly.
Feng Shui Hair Colors by Face Shape
Energy Through Color
Classical feng shui teaches that color carries energetic quality — grounding, warming, lifting, or cooling — that interacts with the natural energy of different face structures. The AI Hair Style Advisor incorporates this layer of traditional wisdom alongside modern style science. Here’s what the guidance suggests for each shape:
How the AI works
478 Landmarks. Zero Data Uploaded.
The AI Hair Style Advisor uses Google MediaPipe Tasks Vision FaceLandmarker — the same technology behind professional-grade computer vision applications — to map 478 precise points across your face. From these, it calculates your face’s height-to-width ratio, forehead width, cheekbone width, and jaw width to classify your shape into one of seven categories.
Crucially, all of this processing happens entirely on your device. No photos are uploaded. No data is stored. Your camera feed and facial measurements never leave your browser. You get professional-level analysis with complete privacy.
The tool also provides fully separate recommendations for men and women — toggling between the two surfaces distinct hairstyle suggestions tailored to each. Feng shui color guidance applies to both.
Quick reference
The One Rule That Never Changes
Every great hairstyle follows the same underlying principle: create the illusion of oval proportions. Oval is considered the most balanced face shape because its proportions align naturally with styles designed around a “neutral” center. When stylists talk about adding height to a round face or softening a square jawline, they’re gently nudging the visual impression toward those balanced proportions.
But balance doesn’t mean sameness. A round face with bold, dark, elongated styling reads dramatically different from a soft oval bob — both work, both are beautiful, and neither erases the underlying face shape. The goal is harmony, not disguise.
