When I was transitioning I used products for relaxed hair when I had more relaxed hair than natural, keracare etc, and did a protein/reconstructor treatment every week or two; affirm 5 in 1. I also straightened my new growth at this point as it was easier to match the natural to relaxed seeing as there wasn't much of it. But most of my time was spent in braid extensions.
When I had more natural hair I started using more natural products like oils, glycerin based spritzes, Aubrey organics, darcys botanicals etc as I now needed more moisture than protein. I also began exclusively air drying.
