I use the sulphate free shampoos and conditioners from Naked bodycare. Available in Boots as well as Boots coconut and almond oil deep conditioner, Boots pink curl cream and Umberto Giannini's Curl Friends Scrunching Jelly.

I've also tried Australian Organics shampoo and conditioner from Holland and Barrett.

I'm also going to try the Curl Keeper substitute KY Liquid (yes, the lubricant) I've just got to remember to pick some up.
Fat does not make you fat. It's actually pretty important.
