I used to use Nice n Easy , but lately it’s not lasting. I’m 55 and my natural hair colour has lightened significantly lately to a silver/white colour. It’s making me look older and washed out. I’ve tried to darken it to blonde but it’s not lasting like it used to. Can anyone recommend a different product? I want to be dark blonde ideally. I don’t want to start using the hairdresser for this, I want to do myself at home.
