Upload a photo and pick a colour. You get a few seconds of video instead of a flat mock-up, which is the only way to see how a colour actually moves and catches light.
An AI hair colour changer shows you a different hair colour on your own photo. Doing it as video rather than a still matters more than it sounds - colour reads differently when hair moves and catches light, which is exactly what a flat mock-up cannot show you.
Face toward the camera, hair fully in frame, even light. Hair tied up or heavily shadowed is the usual reason a result looks wrong.
Be specific - "ash blonde", "copper with warm highlights" beats "lighter".
About a minute.
A short clip you can show a stylist or sit on for a week before deciding.
Colour reads differently when hair moves and catches light. A still mock-up hides that.
Only the hair changes. The point is that it still looks like you.
Run the same photo through a few and compare before booking anything.

Show the stylist a clip instead of describing a colour with words.
Most people sit with the clip for a few days. That is the point.
Stylists use it to show an option without touching anyone's hair.
On a clear, front-facing photo in even light, close. It gets less convincing with tied-up hair, heavy shadow, or when the target colour is very far from your natural one - bleaching black hair to platinum is the case it gets least right, and it is also the case where real results vary most.
There is no point - upload the photo and you already have the answer. It is most useful for a colour you have not tried.
Not reliably. This changes colour. Asking for a different cut in the prompt usually produces something that no longer looks like you.
No. A clip cannot tell you how a colour sits against your skin tone in daylight, or whether your hair will take the dye. Use it to narrow the shortlist, then go talk to someone.
