This is just a quick observation. Its so funny how they say oil and water don't mix but this definitely doesn't apply to natural hair at all! Most natural ingredients for naturally textured hair always have water and oil somewhere in their ingredient list.
Also, some naturals who don't fool around with products always seem to stick with water and some form of oil as their staple and primary ingredient. I actually envy naturally textured hair folk who keep it simple with oil and water because they save themselves a whole lotta time and money! But I'm way too curious by nature to keep it simple!
Thats just a brief on note on my observation of oil and water on natural here.
