Well when I was a natural 4a/b I had a few knots every wash. But the Maxiglide and careful detangling easily straightened those out. Oh and Creme of Nature Detangling Shampoo was the best in those days. Still is, but it makes my scalp flake, so I stopped using it.
Anyways as a texturized head, I don't get any knots at all. Not that I've noticed
and my hair is healthier, longer and better off with a texturizer.
The way that I manage my retouch is to find the part of my hair that is the most coarse, and the thickest new growth and start there. Generally it's the same section EVERY time, the back middle (not the top of my head). I do the nape last and the edges. I only allow my Mizani No-Lye to process for seven minutes, I rinse, apply a reconstructor, rinse, apply nuetralizing shampoo (repeat as needed), rinse apply conditioner, rinse, apply deep conditioner (deep condition with heat), rinse and style.
As you can tell I do a lot of rinsing, and I do it all in the shower, leaving the final rinse for the sink. It all takes about 7 minutes in the shower and 1 hour to deep condition with a heat cap.
I hope this helps.
