Beautiful hair you have! I am like you, on a tight budget and cant stretch to buying the branded CG stuff, but I have settled into a routine where I am having the most amazing hair days, but it has taken experimenting since going CG in February!!
I dont buy expensive stuff. I CO wash and detangle with a really simple very cheap supermarket own brand condish. When I scan the ingredients, it is a very short list, with nothing nasty in it. I scrub the scalp with a cheap tea tree head lice repelling conditioner for kids, also from the supermarket. My final condish is with the same one I CO wash with, but with honey added and a little left in after rinsing.
I use a tiny amount of curl creme after washing, then use Loreal Out Of Bed, which is around £2-3, and I consider that a splurge, thats about as expensive as I can manage!
I don't know what its like in the Netherlands for supermarket brands, but that is all I use and I am getting on very well.
Stick with it, it really is worth all the hassle!
love, Liz x
