One of my friends at work has gone through hair transition. She is a natural medium blonde. When I started working with her she had just modeled for a hair show. They had colored her hair black, it looked great but she was ready to go back blonde recently. Another stylist did what she could but her color resulted in a reddish color.
She then asked me to do her hair to reach her goal color. I did some color correction, added highlights and this is the result...
And yes, she should really be smiling in the after picture!
