I am really not sure what it does other than what I have read about purple or blue shampoo for taking brassiness out.
I am letting my grey grow and have about 4" of grey now but it is light gray in half my fringe and a lot of it is dark gray mixed with dark brown which is my original colour plus a white streak here and there, its very patchy!
The dyed part is a light brown and there is quite a line where the two meet. Is there any sort of toner that would help soften that line. I dont want to start dying again so anything that washes out in a few shampoos would be fine but I find it very confusing so any help would be appreciated.
Is it like a temporary wash in/wash out dye?
