Try buying some purple shampoo and toner. Coz let’s be honest lemon is not gonna work. And if it does, it will be far from the impact you seem to be after. Or bite the Buller and dye your hair. I had hair like yours it used to be white when I was little and slowly became a mousy colour. It was a weird half way colour that made me look old and ugly haha So I dye it blonde now. Even when I get regrowth it blends in and you can hardly notice. Nobody even knows because it looks natural as I don’t go for the platinum look and if you look after your hair properly you won’t damage it. Don’t think you’ll get the same results from LEMON. If there was a natural replacement for hair dye, more people would do it
