How to do No Shampoo Haircare?

I have used profesional hair products for most of my adult life and I am very new to shampoo alternatives. The problem is that I color my hair to hide my greys. I found my first grey hair when I was 16 and my hair started turning grey pretty fast ever since.

So far I have tried a few different types of natural hair cleaning methods and everything I have tried takes the color out of my hair pretty fast.

So does anybody know of a none shampoo hair cleaning method that is safe on color treated hair?
