Quantities and Mixing and How to Colour Hair at Home with Pure Henna Hair Dye
It isn’t easy to gauge the quantity of powder you need if you’re a first timer with henna and indigo. As you get used to using pure henna hair colour you’ll instinctively know how much to use and you’ll build up your own idea of the sort of hair colour chart that you can work within. Having used them once, you’ll have a clearer idea next time how much to use and how to colour your hair with them. On medium length normal hair the standard packs of henna and indigo in the Henna Starter Kit should allow for a good couple of applications, and may stretch to three applications; with cassia you’re mainly applying to the scalp , and then you try to smoosh it around as best you can over the rest of the hair once you’ve covered the scalp.
When you mix henna, indigo, and cassia, be careful to go easy on the amount of liquid you add. A little at a time is important, simply so you don’t flood the powder and end up with ink rather than paste. Press down into the powder to break up the globs as you mix. It’ll look dry and crumbly, but as you add more liquid it’ll smooth out and absorb everything until it’s all smooth like mud /custard / thick gravy. Once you’’ve got a smooth thickish paste - not too thick as it has to be workable - then it’s ready to enter the dye release time zone; ie if it’s henna then cover it up and leave it alone, and if it’s indigo, don’t cover it up but do leave it alone for just a minute; and if it’s cassia obovata, it’s fine to leave it up to 20 minutes, covered or not, before you use it - or you can use it immediately.
Once henna paste is ready to use, you’ll see that the colour of the paste has darkened from green to brown, almost brown black on top - but underneath it’s dull green brown. Indigo paste will turn from green to bluish black. Cassia paste will be a sort of dull frog green. If any paste is too thick, just add a few more drops of water and work the paste a little to get it nice and smooth again. You may want the paste slightly wetter if you’re applying it to dry hair or slightly thicker if you’re applying it to wet hair; the choice is yours. Very gently heating the pastes on the stove will help to get rid of lumps and smooth it all out.
To apply, either section your hair starting at the base of your scalp and work upwards, or just “shampoo in” as best you can - there are no precise hair colour application rules for henna as with hair dyes. You may find it easier to roughly section the hair if it's wet, and just to shampoo in if it's dry, roughly parting it as you go to get it into the roots and along the hair line front, back and sides as best you can; once it's all in, cover and gently press down to get it to seep down to the roots. Don't worry about precision and don't approach it as you would a standard boxed hair dye ..... be relaxed ! It pretty much takes care of itself once it's all in. It's virtually fool proof. You really do not need to pay anyone to do this for you. It's a very straight forward home hair dye. It takes time, and it is messy, but it's worth it ! And so are you.
