Just to add, if you apply a permanent dye too soon after using a colour remover, it will go dark again, even if it’s a light shade.
I would suggest, as another pp suggested to try the Vitamin C & Shampoo mix.
I went from darkish brown to a light copper colour, almost like a light strawberry blonde at the start of this year. I used a colour remover. But it kept re-oxidising so kept going dark after a few days. So I left it for a a few months & got a shwarzkopf colour expert box colour in L9 - the lightest one, like a lightening dye, bleaching one I think. I applied that in really carefully but not to my root area as I knew that would go very light. Anyway it lifted my hair to an unsavoury yellowy colour, as I thought. It would. I then slapped on clariols medium ash blonde 24 wash, which toned it down a bit, but it was still quite warm, coppery, which is what I wanted anyway.
Over the last months I’ve only used semi colours like a medium ash blonde for when my hair looks a bit brassy & tbh I don’t suit lighter colours, I look better with a slightly darker hue. My hair isn’t in the best of condition but I had a good cut after doing all that, but yeah it does dry your hair out.
I do like the colour of the first pic, it looks like a nice auburn.
