Sorry to be a Debbie Downer, but I don't really believe anything topical can help hair grow faster. I think the rate of hair growth is governed by internal systems like hormones.

Just eat a really healthy diet with lots of protein - hair is made up of protein, and get rest.
2/c and some 3A. Modified CG.
Protein sensitive
Highly porous. Color over grey.

Sometimes try roller sets - classic glamor but I prefer my curls.
