Hair Dye Answers

I decided to try a bold move & dye my hair black.. It was a big mistake. I don’t know what I was thinking! It looks terrible! What can I do to fix it!?

My daugher wanted to add natural colored red streaks to her beautiful blonde hair. When it was rinsed out, the streaks had spread, & it’s PINK blotches. How do we get back to her natural color? We need a quick fix, but a healthy one too.
