I dyed my hair from black to ash blonde using a box dye, I didn't want blonde but it showed at the back of the box it goes a nice light brown colour. The colour lightened my hair more than I hoped at the roots. But it's got a reddish tone to it. It's actually a nice colour but doesn't suit me I think. Can I dye it a darker brown without it going green? Has anyone actually done this? Also can I do it on the same dye ?if anyone had tried this please let me know or will purple shampoo help?
Thanks
