I really want to colour my hair darker i have baylage at the moment but i wanted to tone it down to a 7 at the ends will it darken and would volume should i use im a base 7 at the top and about a 10 on my ends

Asked by: Elliexx
I have exactly the same problem, but on the length of the hair there are some subtle stains from the bleaching and it is more of a 9 level, 10 just at the ends really. I am light 7 (the woman at the salon said 8, but my hair looks `mousy´ in the shade and shines almost red/gold in direct sunlight. I would appreciate an answer because I really prefer to tackle this myself at home, I usually have bad experiences at the salon.

Hi so I used the Dia Richesse before and now I have the huge bottle of Diactivateur 9 vol. Does this work as a developer for say bleach and if so which bleach should I use?

Asked by: jackie27
DIActivateur is only intended for use with DiaRichesse or Dia Light hair color.

Hello, I coloured my hair today with DiaRichesse in 4.15 using the 6% volume activator. I love the colour and shade but I've still got a few patches on grey in some areas. If I use the 15% activator with the same shade, will my hair turn out darker?
