I was only trying to hide a bit of grey and tone in to a previous dye job that got lighter and lighter unexpectedly! My hair is mid/light brown with natural chestnut lowlights and very fine. The grey is stark white and thicker hair so it stands out. I'm fine being grey, just not amongst darker hair and with this odd strip effect from the previous dye. Really, I just want to look normal.
So I used what I thought would be one shade lighter than usual - Nutrisse 8.13, hoping it would blend into the older dye and hide the grey, and not be so striking as it grows out. I dyed just the long roots, then combed it through for the last 10min, as per the instructions, then waited for a nice shiny light brown..... Nope. It's quite gingery. Not at all what I wanted. I haven't washed it yet, not sure whether to try the head&shoulders thing of it that will make lightened hair worse!
Last dye job was Casting Creme 600 which was a bit darker than I wanted at first and then got lighter and lighter as time went on, leaving an obvious line. I don't know why it would get lighter and am worried this will too.
How soon can I dye over the top? And am I doomed to have hair that will always take on a gingery tone? I need at least one shade darker I think but how to get back to normal without feeling hideous while it regrows?
