I brought this wax for holding dreads in place and it says it causes fast hair growth is this true?

I really doubt it. Is it Knotty Boy dread wax? That stuff is wicked.I brought this wax for holding dreads in place and it says it causes fast hair growth is this true?
Honestly, the only thing that works for hair growth is the stuff that's in rogaine, which is only for people who have hair loss and it's not found in hair dressing products.
