Thinking about going copper, platinum or pastel pink? Before you book an appointment, see it on your own hair. This tool uses an open-source hair segmentation model to find exactly which pixels in your photo are hair, then recolours them while keeping your highlights, shadows and strands. It also detects your face shape and lets you try haircut sketches that tend to suit it.

Upload a front-facing photo with your hair pulled back if you can, then try eight hairstyles and colours.
- Your photo stays on your device. It is analysed in your browser and never uploaded to us or anyone else.
- Nothing is saved. Close the page or press "Remove my photo" and it is gone.
- Open-source models. Your browser downloads the model files once; see how our photo tools work.
How The Hair Colour Changer Works
- Finding your hair. A segmentation model gives every pixel a score for how likely it is to be hair.
- Keeping the texture. For each hair pixel we keep how light or dark it is compared with your hair’s average. That preserves shine, depth and individual strands.
- Applying the new colour. The chosen shade replaces your colour in proportion to the model’s confidence, so edges blend softly into skin and background.
Everything happens in your browser. You can save the finished image to your own device; we never see it.
How The Haircut Sketches Work
Changing a cut realistically means inventing hair that is not in the photo, which needs much larger generative models that would not run privately on your device. So instead, we draw simple sketches of eight cuts sized to your face, using your hairline, temples and face width. They give you a sense of shape and length rather than a photo-real result. Styles marked with a star usually suit your detected face shape.
Which Cuts Suit Which Face Shape?
| Face shape | Cuts that usually work | Why |
|---|---|---|
| Oval | Almost anything | Balanced proportions |
| Round | Pixie, long layers, top bun | Height and length lengthen the face |
| Square | Waves, curls, fringes | Softness balances a strong jaw |
| Heart | Chin-length bob, side fringe | Fullness at the jaw balances a wider forehead |
| Diamond | Fringe, bob, curls | Width at the forehead and jaw softens cheekbones |
| Oblong | Fringe, curls, bob | Width and a fringe shorten the face |

Choosing A New Hair Colour
- Match your undertone. Warm undertones suit copper, golden blonde and chestnut. Cool undertones suit ash blonde, platinum, blue-black and cool browns. Our AI colour analysis can help.
- Mind the contrast. Very dark hair on very fair skin creates drama; softer contrast looks more natural.
- Think about upkeep. Going lighter usually means bleach, regular toning and root touch-ups. Pastels fade within weeks.
- Protect your hair. A professional colourist can tell you whether your hair can take the change safely.
Tips For Better Results
- Use a photo where your hair is clearly visible against the background.
- Avoid hats, scarves and busy backgrounds in the same colour as your hair.
- Very short or very light hair gives the model less to work with.
Frequently Asked Questions
Is the new hair colour exactly what I would get at a salon?
No. Real results depend on your starting colour, hair condition and the products used. Use this as inspiration and talk to a colourist.
Why are the haircuts drawings and not photos?
Realistic haircut changes need large generative AI models running on servers, which would mean uploading your photo. We chose privacy.
Is my photo uploaded?
No. The hair model and all colouring run in your browser.
