I mixed with hot water and a little salt. I let it sit for a little bit and then mixed with Henna and Amla.
First off, I never let my indigo sit for any length of time. I immediately apply it to my hair after mixing and my hair comes out really really black. It's not like actual henna that it would need releasing time because it doesn't. Try adding it in immediately after mixing and see what happens.
I copied and pasted my recipe and method here and I am a very detailed person so sorry it's so long. There really isn't a whole lot to it though.
Here it is:
My Indigo Mixture for After-Henna Treatment
I only do a very simple indigo mixture as indigo does not co-operate well with a lot of other powders and conditioners or oils. So here is my simple Indigo recipe:
WHAT YOU WILL NEED:
--200 grams, ie, 2 boxes (about 7oz) of indigo
--Distilled water (hot but not boiling water)
--.5 Tablespoons of sea salt
--plastic wrap
--foil wrap
--newspaper to spread on the floor during application
--Old dark towel for shoulders
--Paper towels to wipe up excess spills/droplets of indigo paste
RECIPE INSTRUCTIONS:
-Mix all the ingredients in a plastic bowl to the consistency of a thick yogurt-like paste.
Please note: I make sure my hair is air dried after the henna treatment and free of any shampoo, conditioner and oils.
-I apply the indigo to my henna-ed hair from roots to tips immediately after mixing. The indigo color does not have to release, it must be applied right away because it will lose it's coloring properties if allowed to sit too long.
-I then wrap my hair air-tight for 1-2 hours with plastic wrap and foil wrap.
-I then wash out the indigo with lots of water and cheapie conditioner for at least 8-10 times.
-I end the whole process with deep conditioning for at least 3-4 hours - half of the time with heat and half without. Sometimes I will sleep with my DC on my hair overnight depending on whether or not it's on a weekend and I have the time.
UPDATE:
MY HAIR CAME OUT PRETTY BLACK THIS TIME. I LOVED IT!!!
For my next treatment I might mix the henna and indigo together. I really wanted my hair black this time, hence the separate applications. Indigo is very hard to apply. It does not behave well during application, it drops all over the place and neither does it stick to the hair like henna does.
So I think it's better for me to mix the henna and indigo together before application. What I will do during my next treatment is to let my henna color release overnight, then mix and add the indigo just before I apply the mix to damp hair for easy application - Leave it on for about 3-5 hours, rinse out with cheapie conditioners, and deep condition for 3 hours or more.
