Ever wondered why your hair ends up gold everytime you color it?
The darker the hair the more warm pigment it has in it. When you lighten the hair even slightly the warm pigment is visible. So when you do highlights unless you go light enough to eradicate all the warmth you will at some point need to have a plan to reduce it, maybe not now but down the line.
Now there are limitations to the extent you can remove based on hair condition and actual color but no matter how far it’s gone it can be softened. you may not even need to color it, it could be as simple as using a toning shampoo. So the best thing to do is have a consultation and work out what needs to be done. Remember the more color or chemicals you do the more warmth typically will show itself.
