This is my current method for doing my hair. Normally I'd get my friend Rojan to bleach my roots and dye my hair at the same time as she is amaze at it but I won't see her til I got back to uni in September, so I have to have a whack at it myself for the time being.
I hadn't dyed my hair for over a month and half and it had gone a very pale sea foam green colour, I don't mind it at all but I'm going to a party dressed as Sailor Neptune in a few weeks so need my teal-y colour back ^^
You will need:
Dye/mixing bowl/application brush/sectioning clips/sectioning comb/shower cap
At the moment I mix one bottle of Stargazer 'Turquoise' and one bottle of Stargazer 'Coral Blue' to achieve the colour I want. But I've also used La Riche Directions in 'Atlantic Blue' and 'Apple Green' and once, Manic Panic Atomic Turquoise.
Also consider an extra mirror to see the back of your head if you're dyeing your hair yourself, cling film to wrap your hair and conditioner to bulk up the dye if you don't have enough to cover your head.
Squeeze the dyes into the mixing bowl
Mix them up
Section the hair for dyeing - I use a mixture of applying the dye to the roots with a brush, combing it through the hair and just rubbing it in with my hands. USE GLOVES! I then wrapped my hair in cling film and covered it with a shower cap. You can blast your head with a hair dryer with all the coverings on to speed up the dye and help the colour attach to the hair.
Leave the dye on as long as possible. Most unnatural hair brands use vegetable based dyes with no ammonia or whatever so aren't bad for your hair. Leaving it on as long as possible means you get a brighter colour.
I'm quite pleased with my attempt as usually when I do it myself I discover patches of uneven colour but I combed the dye through this time which I think really helped. xx
