From the conclusions:

TLDR Yes it impacts color. Further reading can be found in the 75 studies that can be found in the references section.
- JR1427 3mo agoWhen most people think of age-related hair greying (which you referenced in your original post), they think of the phenomenon whereby hair follicles stop producing pigments that colour hair. This is distinct from UV bleaching of the pigments in the hair.

- JR1427 3mo agoIf hair greying was mostly caused by UV damage, I would expect that the pattern of greying would be even, and begin on the top of the head. In contrast (based on my own unscientific observations!) greying typically begins in small areas, and often on the temples - not what I'd expect if caused by UV damage.
- gib444 3mo agoNow I'm curious why it starts on the temples (it's where mine started too, then my fringe)
