Interesting article, but don't seem to be able to comment there.
For me, Cantu all the way - it's not just for afro hair.
The co wash is brilliant, along with the curl revitaliser "comeback curl", the curl activator cream... my bathroom is stuffed with their products.
Also, I generally buy in afro hair product stores - about 60% of the price on amazon or boots/superdrug.
And silk pillow cases are expensive, but they make ahuge difference.
