I have just stripped my hair, which was a dark brown. This removed the entire dark colour leaving it a red/copper colour. I had some grey at my roots so I placed a base 7 dye on it. I only left the dye five minutes as I just wanted to cover my grey and give me a nice soft brown.
My hair is now almost back to the very dark brown I started with, what is the reason for this?
When I read your question it sounds as if you did everything correctly but what I think went wrong possibly were the products you used.
If you used the colour remover ColourB4 or something similar, I have found in the past that when you apply a dye after you have stripped the colour it can go super dark or even darker than your starting shade.
What you have to do is use a shade that is around two to three shades lighter than your desired colour. So if you want a level 7 colour then use a level 9 or 8 as the hair absorbs it quicker than normal hair would. I would do a test piece to see what results you get.
If the hair feels in good enough condition then I would use the colour remover again and re try with lighter colours to get the result you are after.

The stripper may have made the hair porous, making the No.7 dye grab and go black. You really need to go to a salon to sort this out.
