Hello Everyone...
I am a newbie, I posted an introduction in the "Introduce Yourself" thread.
About twelve years ago, I had gotten highlights that didn't come out right because my stylist put waaaay too many blonde streaks through my entire head of hair. I wanted to calm down the blonde so he suggest the only way to get all of the blonde out was to dye it black to cover up the blonde and then to re-highlight a month later. I washed my hair once a week for two weeks before the next color and you wouldn't believe it, the black dye started coming out and I had a head full of lime green hair! Well, I didn't remember my art classes in junior high school: Black mixed with Yellow = Green. I regretted ever agreeing to this, but he was supposed to be the professional. I was do devastated. I had to wear a hat the rest of my high school year (thank God graduation was a month away).
I thought my hair would never recover but it did. I don't remember exactly what I did to correct it, but I do remember constant conditioning and wearing protective ponytails everyday. Now, ponytails have been my main style for the last 15 years. They are never outdated, always in fashion.
I hope I am not being too forward being a newbie, but I would suggest you go to a professional stylist and have them correct the color to prevent any further problems.
This is just a suggestion.
Thanks.
