It is common with blonde hair and photographs. Something to do with the way that light bounces ... I can't remember exactly, but a shadow that looks like roots can be seen on a perfectly natural blonde.
Thanks for the explanation. Cannot say it’s true for Elin but I have seen blond women I thought sure looked “born that way” with seemingly dark roots. You have the answer.
Is Kate Moss natural?
In some photos Elin has hair that looks plated together and stuck together which is a sign of using hair coloring. Lots of women get that stuck together effect and would look prettier if they skipped the coloring. In other words some hair takes to coloring better than others. If you can pull it off then do it. But cheap looking dye jobs .....
