How to get rid of brassiness in highlights?
I've recently had my hair highlighted and I'm struggling to get the color right. My hair is naturally dark brown and I asked for carmel & light blond highlights, and the first time my stylist tried, she didn't give me enough of the lighter color around my face, so I went to see her a second time.
She brought out some swatches of hair and asked me to pick what color I'd like for the ligher highlights and we both agreed on a light beige, which we tested by holding up to my hair. It looked great, so she foiled my hair again and now I have more lighter highlights around my face, but...that light beige color is nowhere to be seen. Instead, the highlights are orangey and brassy - not flattering on me at all.
I'm hesitant to go back to her yet AGAIN, so is there anything I can do on my own to tone down the brassiness? I'm thinking of getting a blue-based toner, but if I do, should I use it all over or just on the top layers, where the highlights are? And if that's not the solution, what else can I try? This brassy color is really embarrasing.
