My usual salon is closed for the holidays so I got a box of Nice and Easy a shade lighter than my usual shade as mine is a bit sun bleached and faded. The medium brown that I got is almost black! I look awful and washed out. I've googled and found that Fairy liquid is recommended if you hair is in good condition, which mine isn't. Or Head and Shoulders. I don't want to throw good money after bad so can anyone give me advice on what I can do to lighten it?
