I don't necessary use henna, but i do use cassia. What i have learned is that, when making a paste for your hair, its ALWAYS best to make a smooth paste consistency (meaning NO CLUMPS), for a successful wash out.
I also agree with CURLICARIB, add the tea last the helps to achieve a smooth paste, from there you would be able to tell if you need more or less tea (depending how much of a paste you have mixed). HTH.
