I also used Wild Growth hair oil back in the day. I remember it being great to enhance curl formation if used on my damp natural hair after washing and before braiding it and going to sleep. I think that if I put it on damp hair, the smell wouldn't be as strong once my hair dried. Other than that, I believe I used it in oil mixes (deep conditioning, hot oil treatments) and on my scalp and ends as an overnight leave-in before washing the next day.
Oh, and when put on damp hair, it definitely makes hair smooth and shiny.
I do seem to vaguely recall that the original ingredients were changed at some point, though. The ingredients now might not be the same ones as when the product was first released. Now, I'm wondering if that was the reason I stopped using it.
