Hi ladies (and gents) I'm thinking of trying Wella colour touch plus at home after my usual more" natural " less chemical hair dye (tints of nature) is just not taking properly any more. Can anyone tell me how dark they come out please ? I've been using a depth 4 medium brown in previous brand. I have about 10 % grey and just want them blended in. Want to avoid having root regrowth very visible so thought a demi permanent would be the thing to go for. I've been sheilding and do not feel safe going into a salon and probably won't do until there is a vaccine!
