Upload a photo with visible hair
Choose a portrait that includes the hairline, the lengths you want to compare and enough surrounding background to see the edges. A tight face crop can leave out the most important area for hair color try on. Use soft daylight and avoid a strong colored lamp. Hats, heavy filters and wet hair can conceal the usual texture or make the starting shade ambiguous. Check the original at full size before choosing a new color, especially where dark hair overlaps a dark top or blends into the background.
Choose a shade to preview
Begin with a broad color family such as brown, black, blonde or copper. For hair color try on, compare depth and warmth separately: a darker shade can change contrast, while a warmer shade can change how the skin beside it appears. Use the color choice as a reference rather than a salon formula. Selecting a shade alone does not recolor the photograph. Keep a written description of the shade you like, including whether it is lighter, darker, cooler or warmer than your starting color.
Compare colors with the same input
Hold the portrait, crop and lighting constant for a useful hair color try on comparison. If those change between images, one shade may appear brighter for reasons unrelated to the color choice. Look at hair edges and facial detail as well as the color itself. Shadows should still describe the strands, and a shade comparison should not quietly turn into a new haircut. View the images at the same zoom and screen brightness. Keep the unedited portrait beside the comparison so you can spot changes beyond the hair.
