I have given up dyeing and have quite a bit of grey now but it is very patchy and have been using various temporary colour depositing shampoos/conditioners but thinking I want to have it med/dark brown again but dont want to go the permanent route.
Am I right in thinking that anything where you mix the colour and developer together is going to be permanent even if it is called semi permanent? I don't want to have to start the growing out process all over again so any recommendations for something truly semi please?
