Crazy colours hair dye

[thishouseisashittip]

Hi all, just after a bit of help if possible please. I am looking for a really good hair dye in bright colours the last more than a couple of washes! I had my hair dyed purple at a hair dressers 2 weeks ago (full deal, bleached etc paid £100!) have only washed it 3/4 times since and it's already fading 😩. Just wondering if anyone could tell me the best brand of home dyes I could buy keep it topped up?
I have already tried bleach London which isn't too bad, is there anything better out there?

Arctic fox has great colour pay off but really bright colours do fade much quicker.

Manic panic - my hairdresser-applied rainbows last a good 2-3 months and then I top up at home with the main colour, usually teal. Washing in the coldest water you can stand with a pH balanced shampoo will help it last too.

Have had good results with Directions dyes in the past but Manic Panic are definitely more vivid and longer lasting on my hair.

Sorry for terrible crop, but pics are 11 washes in :)

Try Crazy Colour brand, I have used it for years and lasts for lots of washes.
