I've used Colour B4 about 6 weeks ago, my hair is medium to dark brown, and finally has got the old hair dye out.
Its not a very exciting colour naturally, i was hoping its gleam andshine would carry it off but its a bit of a dishwater colour... rather than using a permanent dye that will need roots doing and have more obv root growth,I was thinking of using castings as they sem to be semi permanent andhave nice colours..
any advice?
