Acai is very healthy for hair growth, not to mention skin and nails as well. I actually market a product that contains Acai, as well as Cupuacu & Yerba Mate'; 3 of the 5 superfood recently featured on the Today show. one thing I really like about it though it the Yerba Mate' actually turns your grays back....great bonus cuz I tried Henna once, never again
I have a link in my siggy for a sample if you want to try some
