After a lot of frustration involving dye washing off after a couple of days off my White temples and having to prelighten before using boxed dyes (and it still failing) and attempts at going grey I bought this. It works!
So happy had to pass it on. I mixed a tube's worth (50ml) with 75ml of cream 20 vol developer. It turned out a really thick consistency and stayed where I put it. I would say owing to the thickness you have to use a bowl and tint brush. For the first time ever my hair feels in better condition after colouring it.
