How do I get rid of some of this semi permanent colour?

[FuckASilverLining]

So I had blonde hair and re bleached it.
I wanted it lilac blonde
It was a bit brassy so I used a manic panic purple in conditioner but it's gone way too lilac.

I have a party Saturday.

How can I take a lot of the purple out without touching bleach again?

Crush vitamin c tablets and mix with head and shoulders into a paste. apply to your hair and leave for half an hour or so. Wash out and repeat if needed. A word of warning, it might not wash out evenly. I had together rid of an artificial red and this is very effective but takes time.

I would also buy a deep conditioning treatment for after.

Washing up liquid, a few times, be very generous with amount used, and as above,be prepared to use a good conditioner afterwards.

I used it to remove a lot of a castings dye

Worked brilliantly. Thankyou!
