What is the best free AI hair color changer in 2026?

Pick one that changes the colour and nothing else. We tried seven colours on four people and fixed what our own tool got wrong.

One of the best free AI hair color changers in 2026 is N33: add a selfie, pick one of seven colours, and get four takes in about a minute. We ran all seven on four people. The test found three faults in our own tool; we fixed two fully and one in part.

A note before the comparison: we make one of these tools, and it is the only one we tested ourselves. For the others, every claim below comes from their own pages, linked where it appears and checked the day this guide went live.

What we measured ourselves

2026-10-30 → 2026-10-31

16 of 16jet black pictures that came out black, not navy or blue, after our fix

Four portraits of adults: a woman with long straight hair, a woman with coily hair, a man with wavy hair and a man with a short cut. Each got the tool's seven colours, platinum blonde, copper red, chocolate brown, jet black, pastel pink, silver grey and blue ombre, four pictures a run: 112 pictures, 60 to 151 seconds a run. Every run kept the face, clothes and background, and the coily hair kept its curls in all 28 of her pictures. Three faults: jet black came out navy or blue, the blue ombre grew the men's hair to show the blend, and short hair gained a fringe. After our fixes jet black was black in 16 of 16, the ombre lengthened the hair in 2 of 16, and the short cut still gained a fringe in 11 of 28.

A woman with coily black hair in a mustard top in a park — Two of the four people in three colours each: only the colour changes, the curls, length and parting stay.

The same woman with platinum blonde coily hair — Two of the four people in three colours each: only the colour changes, the curls, length and parting stay.

Does an AI hair color changer work on curly hair?

Ours did: the woman with coily hair kept her curls in all 28 pictures, from platinum blonde to blue. A colour change is gentler than a new cut, which is where we saw curls straightened before.

The same man with his short cut kept and coloured blue — The same short cut asked for a blue ombre: our first prompt grew it to the shoulders to show the blend; the fixed one colours the hair he has.

A man whose short hair grew to shoulder length with a blue ombre — The same short cut asked for a blue ombre: our first prompt grew it to the shoulders to show the blend; the fixed one colours the hair he has.

A man with short black hair in a denim jacket on a city street — The two men after the fixes, and jet black that now reads as black.

The same man with short platinum blonde hair — The two men after the fixes, and jet black that now reads as black.

Before the fix: the woman's jet black hair came out navy blue — What went wrong: jet black was navy before the fix; after it, the ombre can still add length and a short cut can gain a fringe.

The wavy-haired man with a blue ombre, his hair a little longer than in the photo — What went wrong: jet black was navy before the fix; after it, the ombre can still add length and a short cut can gain a fringe.

Why does my short hair look different after a colour change?

Some takes restyle a short cut while colouring it. In our test a short cut gained a fringe in 11 of 28 pictures after our fix. Each run gives four takes, so keep one where the cut is yours.

AI hair color changers compared, from each service's own page, checked 31 October 2026

Tool	Free use	Account	How you pick the colour
Fotor	Free online, it says	Not needed to try	24 named shades or any custom shade
YouCam	Free app	Not stated	Presets or a colour picker; ombre and multi-colour
PixelBin	Three free actions a month	No sign-up for those	A text prompt, highlights included
Picsart	Uses credits	Sign-in required	A text prompt naming the shade
Airbrush	7-day free trial of the app	Not stated	A colour from the list
N33 (ours)	Free to start; a try uses a little energy	Yes, free	7 colours; any colour typed in the photo editor

Can you try a colour that is not in the list?

Yes: type it in our AI photo editor, such as honey blonde or copper highlights, and say to keep the haircut exactly as it is. Naming the length and texture keeps the model from restyling the cut.

To try it, open our hair color changer and start from one of its example selfies. For a new cut rather than a new colour, see our test of the best free AI hairstyle changer.

Questions and answers

Is there a free AI hair color changer?

Yes. Ours is free to start with no subscription, Fotor says you can try its changer without an account, and PixelBin gives three free actions a month.

How realistic is an AI hair color preview?

It shows the shade on your own hair and light well. A real dye also depends on your starting colour and how it lifts, so take the picture to your colourist as a reference.

Why did my black hair come out blue?

Some models read jet black as blue-black. Ours did until a fix during this test; now it draws a neutral black.

Will changing my hair color change my haircut?

It should not. Long and curly hair stayed as it was in our test; a short cut sometimes gained a fringe, so pick the take that keeps your cut.

What happens to the photo I upload?

On ours, it is used only for the run and deleted when the run ends; the pictures stay in your Generations until you delete them.
