For purposes of deep conditioning, instead of mixing all of those powders in water, where you run the risk of clumps, the warm oil dissolves it. Therefore, if you mix all of the powders in an oil (for me it is coconut oil) and stir lightly while using the double boiler method, it dissolves the powder to the point where this dark oil is extracted. When I tried mixing the powders with water only, I had a HUGE problem getting those grains out of my hair because it was clumpy so a lot of the powder clumped and was not fully dissolved in the water, if that makes sense.
I just rinsed it out and I'm now deep conditioning. My rinse was GRAIN free and I think the oil method along with the addition of coconut milk, which is sort of slimy in texture, aided in a grain-free rinse and my hair is sooo much stronger. Also, I've also noticed that once I two strand twist my hair (I braid at the base) and let it stay in for a week, I have some new growth. Not an inch or anything, but it is very noticeable.
I made a large batch because I have a lot of hair (very thick) and I used every single drop of it because I make sure to coat every strand while concentrating on my ends.
Try it one day and let me know how you like it, whether you use it in coconut milk or just use regular conditioner. If you opt to use a regular conditioner in conjunction with the oils and powder, that's an excellent deep conditioner.
There is a link below regarding the benefits of coconut milk. If I'm not mistaken, I THINK she use to be a member here on this board. I'm sure someone could chime in and confirm this.
