I definitely feel your pain. I'm now doing okay with the ArcAngell, but certainly don't get 4-5 day hair the way I used to with the Graham Webb. On the other hand, I do know that it's at least partially the haircut.
I think I said this already, but I think I do better with Trader Joe's Suave Conditioner, too. For some reason it helps the curl formation.
Good luck - and let us know if you find anything great!!
