Lamazuna solids shampoo just cleans your hair, no residue, no need to do an apple cider vinegar rinse or a bicarbonate spray.
Found online for about £10.
Had to share as it's taken me a while and after lots of experiments this is the best one.
For the record I have fine, blonde hair and wash it every other day.
I don't work for Lamazuna either - I'm just thrilled to find this one and wanted to share with others.
