Hi, I've recently gone from a light baby blonde colour to darkest brown / black. It looked nice at first but as i've washed it, the colour has faded and became like a reddish tone. Not liking the colour, i decided to go back blonde. I first put on a pre lightener, then a blonde dye. It has worked and my hair is a light colour but it now has a gingerish / beige tone to it which looks awful! How can i go from this to a nice light blonde again???!!! please help!
