Going from brunette to blonde or trying copper red is hard to undo: color removers, toning, grown-out roots. The hair color changer shows the result first — on your own photo, not on a catalog model.
Upload a shot where your hair is clearly visible and not tucked under a hat, then pick a shade: blonde, platinum, light brown, brunette, black, copper red, ash blonde, balayage or pastel pink. To change only the color, keep your haircut: choose “Keep my haircut”. Or try the color together with a new cut — up to four haircuts at once, each a separate photo in the chosen shade. Refine the nuance in words: “slightly darker roots”, “warm honey undertone”.
Google's Nano Banana 2 recolors the hair and nothing else — your face, skin, makeup, clothes and background stay exactly as in the original. Each run tries one shade: to compare blonde and copper, run it again with another color. Every result is saved in your history, ready to show your stylist.
