corn starch 
baking soda 
drawing charcoal (for turning dry shampoo black, so there will be no white residues on your dark hair!!!)
Grind drawing charcoal (buy at artist shop, perhaps also activated charcoal powder would work) with spoon on the shallow plate.
mix cca 1 part of the grinded charcoal with 2 parts of corn starch (it absorbs grease) and 1 part of baking soda (it absorbs odour). You shoud experiment with the quantity of charcoal, the more you add, darker dry shampoo you wil get.
If you have brown hair (brunette), you can add grinded brown sidewalk chalk, for bluenettes blue sidewalk chalk, for lightbrown hair add yellow or light brown sidewalk chalk etc…
apply the mixture in your hair, wait 5 minutes and rubb it off with a towel. You dont have to rubb off all of the powder, becouse it has the same color as your hair.
Dry shampoo is a great solution for dyed hairs becouse it reduces the need for hair washing and therefore preserve the color and prevent its fading. It works great for my hair dyed with natural indigo (indigofera tinctoria mixed with hot water 65°C and 1/4 tbs of non iodic salt left immediately after mixing for 30 minutes on extra clean hair washed with dishsoap).

Then, my hair-stylist suggested the Tea + Protein Shampoo from the Made from Earth line. I was hesitant at first because I didnt think organic shampoos were anything special, but I decided to try it.

It took a few tries, but now I only have to wash my hair every other day! Hooray! Its a thick shampoos so it doesnt run through my fingers and down the drain before I can even get it onto my hair!

I saw a HUGE improvement on my oily hair – highly recommended if you are trying to have normal hair. To avoid overdrying, I use their conditioner also.
