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 have quite brassy orange undertones in my hair with some new grey. I have mixed 9A 2/3 with 1/3 of 050 Cooling purple and have almost got my natural colour. Much better result than any supermarket colour as with some trial and error can get the perfect result.
I used this shade with the 050 cooling violet mixed in from recommendation. Wanting to lighten slightly but without coppery tones..My hair is medium brown but from supermarket colours had gone brassy/coppery... really happy with the result it has lightened and not brassy at all... love it!
Quick postage, great product range
I was really impressed with these products. I have dark blonde hair and this toned and lightened my hair and I didn't even leave for as long as recommended. Will be purchasing again!
Thought I’d try a permanent instead of a toner. While the product and colour is nice, it went around four shades darker than expected. My hair was a very light yellowy blonde, yellow tones now gone which is great, but is quite golden and very dark.
