definitely 4a, but you know just because your friend uses 4a products and it works for him it may not work for you. At least this has been my experience with my own fro and talking to people.

Don't get discouraged if after your first product it does not work, keep in mind you are going to have to experiment!

Best of luck and GRO YO FRO!
