Hello from me + help please!!

Actually, having just checked in normal daylight, pale blue is just one of many shades of the bleached area including dirty pond green, gold and turquoise! Arghhh!!!!

Don't panic! You'll be just fine. You will need to remove as much blue as you can before you start over though. Use Head & Shoulders or Fairy Liquid to wash your hair a few times and get rid of as much blue as possible. Then try a bleach bath just on the darker lengths of your hair. Do that once a week and you'll have a better base but here's where I think you went wrong:

Last night I took the plunge and put 40% Jerome Russell bleach all over - I had white/yellow patchy roots and coppery streaky bits throughout. It barely touched the ends!

Ok, I'm guessing you didn't pile the bleached hair up on your head while you were waiting for the bleach to process. Bleach needs heat to work and it works faster at the roots because of the heat from your head. So next time, pile it up, cover it in plastic, warm it with a hairdryer every now and then - not too hot though - and that should help.

So I thought there was nothing for it but to stick the dye over (Manic panic After midnight Blue) - I left it on over night, and this morning I have patchy pale blue roots and the rest looks brown again!

This is because you didn't neutralize the colour first. Blue needs a good pale base to work on and the hair needs toner to make it a more natural colour. Otherwise you're mixing blue with orange (blue dye, brassy bleached hair colour). Try mixing blue and orange in a paint pot and I bet you get a similar colour to your hair - brown.

The best way to get blue is to take your time, bleach bath down to a good pale base colour, preferably the colour of the inside of a banana peel. Then use toner (99p at Superdrug) then use the dye and you're away!

So get as much blue out as you can then start again. Don't add more dye to your hair as it'll give the bleach more work to do and you only just bleached it so you'll ruin your hair too. Wait a while before bleaching, strip the colour with Fairy Liquid or Head & Shoulders, make sure you bleach bath which is much gentler and you'll be fine.

Thanks very much for your advice 🙂
