This colour must be mixed with developer - the dedicated Wella Color Charm 20 Vol Developer is recommended.
Always mix Wella Color Charm Permanent Hair Colour in a 1:2 mixing ratio. This means you need twice the amount of developer to colour.
One 107ml bottle of Developer is enough for one bottle of 42ml Permanent Colour.
Apply the Permanent Colour to dry hair and allow to develop for 30 minutes or up to 45 minutes for additional depth or grey coverage.
I love this dye so much already! It doesn’t give off that inky black that you get from box dyes, this is such a natural black so soft and lovely! Amazing coverage and the formula is easy to work with. Only buying this from now on!!
