How can I get the pink out of my hair?

Hi everyone!

So Ive had my hair pink for along time (the whole thing). It is a light bubblegum pink. I thought i would want this color until I decided to go back to my natural color (black) but i now want to dye it bright, fire-truck red. I did a test strand over the pink and it came out like a fuchsia color, not the bright red i wanted. I only left that dye in for about an hour (I use ion color brilliance brights). Is there a way I can get the pink out of my hair that wont damage my hair that much? I tried bleaching it before but it doesnt come out all the way. Or should I just try leaving in the dye for a few hours?

Thank you!
