something to help with growth and moisture.

I was thinking of making a concoction of wild growth oil, the virgin hair fertilizer & rooted treasure jamaican black castor oil. I get dandruff pretty bad & really want to focus on growth & moisture. I plan on starting up a new weekly wash routine, I wanted to add this concoction by using it a few nights out of the week. Please give tips if you have any or any recs/something I may not necessarily need. I’d really appreciate it.
