WHY

Will you still love it after the cut?

  • “What if the big chop doesn't suit me?”

    The bolder the change, the harder it is to commit.

  • Box dye never quite looks like the box

    The swatch on the package and the hair on your head rarely agree. Coloring at home is always a gamble.

  • Words only take your stylist so far

    “A little darker.” “Softer, but not too soft.” Nuance gets lost somewhere between the chair and the mirror.

So we built a way to try it first.

FEATURES

Everything it can do.

COLOR LAB

Hair color, in thirty shades.

From jet black through copper and blonde to turquoise and silver — the very same thirty shades that live inside the app, right here on this page. Tap a swatch and watch.

Rose Pink#FF66CC

In the app, the hair in your own photo takes on the shade you pick here.

STYLE CATALOG

Hairstyles, in twenty-two cuts.

Eleven for women, eleven for men — buzz cuts to long waves, with every bob and perm in between. Whether it suits you is no longer a question you answer after the cut.

AI QUALITY

Your face stays. Only the hair changes.

State-of-the-art image editing AI leaves your outline, your expression and your skin exactly as they are, and rewrites the hair alone. A before-and-after slider lets you study the difference at your own pace, and every result can be saved, shared or found again in your history.

FAQ

Questions, answered.

What kind of photo gives the best result?

A bright, front-facing shot with your whole head of hair in frame. Hats and heavy shadows across the fringe can lower the accuracy.

What happens to the photo I upload?

It is used only to generate your simulation image. See our Privacy Policy for the full details.

Which devices and languages are supported?

HairSim runs on iOS and Android. The interface is available in four languages: English, Japanese, Korean and Traditional Chinese.
