How she missed: Lovely pink undertones in a complexion like Johanna's are overwhelmed by a red-pink haircolor.
It's a hit! Frédéric brought out Johanna's startling green eyes with a warm chestnut base color and amber and copper "flame" highlights applied at different places along the hair strand, including the tips. He gave her an angled cut to add body and movement without losing the length she liked. Keeping the highlights closer to the tips around her face, so that the warm brown contrasted with her skin tone, brought out Johanna's exquisite features.
The point: Your haircolor should complement, not match, your skin tone.
