Notes on achieving great blue hair, things that work for me personally
Current
About Bleaching
Pravana: Blue
Don’t wash your hair for a few days before you bleach. Be a greaseball. This helps protect your scalp and your hair.
The Blues
I use 40 vol peroxide for the first rounds, then 30 vol peroxide
it’s good because it starts dark and then fades over time
Olaplex? I don’t need it.
@me Never go to the salon to get coloured ever again. You can do it yourself!
Tried
Bonus purple: achieved by mixing a bit of Punky Colour: Cherry Red (that’s from a 10 yr old jar)
Punky Colour: Midnight Blue
Punky Colour: Atlantic Blue
Punky Colour: Lagoon Blue
Wash your hair a day or two before adding the colour
Joico K-Pak Color Intensity: Cobalt Blue
For me, it usually takes 3-4 rounds of bleaching
Manic Panic
Didn’t try
Bleaching Process
Arctic Fox
I like a 2:1 developer:powder ratio
Special Effects
Hair... there are layers of hair... the head is a sphere...
Maintenance
just use really cheap shampoo, it doesn’t take as much colour out
You gotta section
wash with cold water
make sure you don’t put too much in a section
paint the top of the foil, which touches the underside of the hair
be generous with the bleach
make sure the bleach doesn’t dry out. spritz it with a spray bottle and cover your head with a plastic bag to trap the heat and moisture
use a lot of foils

Post-Bleach
Condition your hair after you bleach
Wait ~3 days before bleaching again
