What Is a Hair Curl Type Test?
A curl type test uses AI-powered image recognition to classify hair into recognized curl categories, from Type 1 straight through Type 4C tightly coiled, in a single scan.
Instead of answering multiple quiz questions about porosity or styling habits, shoppers simply show their hair to the camera and get a pattern classification instantly.
How to Use the Hair Curl Type Test? Two Simple Steps!

Snap or Upload a Photo
Turn on the camera or upload an existing photo — no special lighting or angle required, since the model adjusts for typical selfie conditions.

Why Use AI?
Which Products to Use?
A curl type test analyzes a photo of your hair with AI to classify it into a recognized curl category, ranging from Type 1 (straight) through Type 4C (tightly coiled). It gives an instant read on pattern without requiring a multi-question quiz.
Curl types run from Type 1 (straight) through Type 2A-2C (loose to defined waves), Type 3A-3C (loose ringlets to tight corkscrews), and Type 4A-4C (springy to tightly zig-zagged coils). Most people have more than one pattern across their head.
Because the test reads the actual strand pattern from an image rather than relying on self-reported answers, results tend to be more consistent across repeat tests and less dependent on how well someone can describe their own hair.
Yes. Chemical treatments, heat styling, hormonal shifts, and hair damage can all alter curl pattern, so offering the test as a repeatable tool helps customers track changes rather than relying on a one-time result.
Perfect Corp's Hair Type Analysis API lets brands embed the same underlying technology into their own e-commerce site, app, or in-store kiosk, pairing curl classification with product recommendation logic.
