Hi people! I'm not up to date with colour these days and I have been putting Wella 12 high lift tint on my sisters hair for some time now but it's too warm and no longer covers her grey. I knew it wouldn't cover her grey as time went on but also it just seems to warm for her complexion now. I need to do her regrowth soon and not sure what colour to use on them and also what to use to cool the length and ends as her hair is quite long. It is in very good condition so that's a bonus! Many thanks for some advice!!
