Why not go into a health food store and enquire there about their natural conditioners???. I use alchemy - $11.50 250mls, $25 for 500mls. You need the tiniest bit, size of a 10c piece.......
I personally would be steering clear of supermarket shampoos......look at the back of your dishwashing liquid ingredients, then look at the back of your shampoo ingredients....guarantee there aint much difference...ugh !
