I'm 4a/4b, and not that I don't like my natural hair, it's just, I need manageability and don't have multiple hours a day detangle and style. I have about 5 inches and have never texturized straight from my natural state. I still want to retain my coil/curl pattern.

1. What is the best product?

2. Do I apply to the root and ends?

3. Is it supposed to be combed through, smoothed out?

4, Is it done on wet hair?
