I avoid the darker shades, but to be honest, I haven't any afro-carabinas, so can only comment on our friends from the sub-incontinent. They tend to want to haggle, as if in a market somewhere, and don't want them done very often. It's like they can't make up their minds; they either want them cleaned or they don't, and these chaps can't find a happy balance.
Birds custard's naff, Ambrosia all the way for me!
