First, this is a cleanser, not a shampoo, so it will clean your hair amazingly well and get rid of all the scalp-yuck you may have, but it won't bubble or lather at all.
You will need:
Rain water, filtered water or spring water
Bentonite clay powder (I get mine on eBay)
Green tea, bag or leaves is fine but if you use loose leaves you'll need a super-fine strainer.
The clay is the cleanser, the honey is the conditioner but also acts as a cleanser and the green tea is the rinse. Green tea will leave your hair extra silky and shiny. Regular green tea is better than decaf for this because caffeine reduces hair fall, but either is fine if you're not concerned with that or only have decaf.
You will also need:
A plastic squeezy bottle
Using a non-metallic spoon, measure out one tablespoon of honey and put that in your plastic bottle. I usually use a funnel for this but I can't find my kitchen funnel right now so I just poured and hoped...
...and got honey all down the outside of my bottle.
Anyway, you're more organised than me and have a funnel, so now your bottle looks like this:
To that, again using a non-metallic spoon, add two teaspoons of clay powder. It will look something like this:
Mmm! Clay-y. Meanwhile, you can have a cup of green tea brewing. I brewed mine in an infuser because of the whole funnel thing, I needed a pouring lip, but obviously a normal cup or a glass is fine. Let it brew for at least ten minutes.
When the green tea has brewed for a while, pour it into your bottle, leaving some space at the top for cold water.
Fill to the top with cold water, put the lid on and shake well to combine all the ingredients. It should end up looking something like this:
Take the lid off the bottle to let the mixture cool down for at least five minutes, as you're going to apply it to your head while it's still warm. To use, I apply it to my dry hair in the shower and let it sit for several minutes before washing it out, even though I have quite long hair, I find there's enough liquid in the bottle to thoroughly wet my hair, you might like to apply it to wet hair and that's completely up to you, I don't think it really matters. Just make sure you get the mixture on all of your scalp, as that's where all the buildup is that makes your hair greasy and makes your head smell funny.
Unlike regular shampoos and conditioners, if you don't quite wash all of this mixture out of your hair, it won't do any damage at all.
