This is a picture of me from last summer, with some very heavily-highlighted blonde hair.
Since my hair consists of so many different colors, when I dyed it last, I definitely had some streakage, which did NOT look good. So, I did my research this time and decided to spend the extra $4 for John Frieda hair color foam. (It costs about $12 for a box.) I am pretty happy with the results, but you can see for yourselves.
