Why does my hair look red in this photo

Lucysl

My new identification photo makes my natural brown hair look distinctly reddish, although I have not dyed it. It looks different in my usual mirror. Previous daylight pictures look less red. I am trying to work out whether the difference comes from the light, the camera, or the printed photograph. I found hair color analysis while searching for better language to describe what I see. I am only trying to describe my existing color. A simple comparison would help more than a makeover. Would you take a fresh picture beside a neutral background and compare it with an unedited daylight image? Both pictures can be taken without filters. Matching the framing should be straightforward. The printed version is what worries me most. Where would you start the comparison? I would like to know whether a retake is worth requesting before assuming my everyday view of my hair is wrong.
