Has anyone put apple cider vinegar on bleached hair?

Did it affect the colour?

(would be especially useful if you bleached from very dark hair to very light)

Nope, I've been bleaching my hair for years (with a few periods of going diff colours), from dark to light and I've never heard of putting acv on. Why what's it supposed to do? :)

I should add I bleach from dark brown to v icy pale pearl platinum all over.
