Will light ash blonde hair dye on my dark golden hair lighten it to a paler, ashier blonde?
It really does depend on what level your hair is now. You say dark golden blonde or light golden brown. So, I’m going to guess that would be about a level 7. You can usually lighten your hair two levels with a box of hair dye. So, you might be able to get yourself to a level 9 which is really quite light. I don’t think you should go ash though. It won’t change the red (red is hard, even for hairdressers to change) but it might make your blonde greenish or bluish. Stick to golden. It probably suits your skintone better anyway.
