Is there a free face shape detector that recommends hairstyles?

Find your face shape, see which cuts suit it and why, then preview one on your own selfie — not on a model.

In short: Yes. FaceTwin detects your face shape free, with no sign-up and no upload: 68 landmarks in your browser name one of six shapes and show the ratios. You then get haircuts picked for that shape — women’s, men’s and colour, from 28 styles — and can try one on your own photo free with AI. The try-on downloads as a JPG; more try-ons start at $1.99.

Which free face shape detector also recommends hairstyles?

FaceTwin does both for free. Upload one front-facing selfie and the detector places 68 landmarks in your browser, measures face length, cheekbone, jaw and brow widths and jaw angle, and names your shape — oval, round, square, heart, oblong or diamond — with the ratios behind it. Your photo is not uploaded for this and no account is needed. The hairstyle tab then lists the cuts suited to your shape from 28 styles (14 women’s, 10 men’s, 4 colours), and every shape guide explains three go-to cuts and why they work. To see one on yourself, pick a style and the AI changes only your hair — face, skin and background stay as they are. Your first try-on is free in HD with no watermark; after that, $1.99 covers two more and $4.99 covers five.

Frequently asked questions

Is the face shape detector free?

Yes, free and unlimited with no sign-up. The shape, ratios and hairstyle suggestions are computed in your browser.

Can I see a hairstyle on my own face?

Yes. Pick a cut in the hairstyle tab and the AI redraws only your hair on your selfie. The first try-on is free in HD with no watermark; more are $1.99 each or five for $4.99.

How many hairstyles can I try?

28: 14 women’s cuts, 10 men’s cuts and 4 colours. The ones suited to your detected shape are listed first.

How accurate is the face shape result?

It measures your proportions rather than guessing, but a photo taken too close or at an angle can change them. Hold the phone at eye level, arm’s length away, hair off your face.

Is my photo uploaded?

Not for local lookalikes or face analysis: the model runs in your browser, so your selfie, landmarks and descriptor stay on your device. AI portraits, including the first free one, and full reports send your photo through our server to the AI provider after a free first-portrait request or a credit purchase, and separate upload consent. Reports also send your numeric measurements. FaceTwin does not save the original photo; it is discarded from request memory after processing.
